to make converts of the unprejudiced who had opposed | six officers, sixty-three were killed or wounded, with him. With a single observation, he has rendered of no avail an elegant and lengthy discourse, and determined the fate of a question of importance."

Franklin had conducted himself so well in the office of postmaster for the state of Pennsylvania, and had shown himself so well acquainted with the business of that department, that it was thought expedient to raise him to a more dignified station. In 1753, he was appointed deputy-postmaster-general for the British colonies. It is said that the revenue from this source, in Franklin's hands, yielded to Great Britain three times as much as that of Ireland. In 1754, Franklin drew up the celebrated "Albany Plan of Union," the purpose of which was the establishment of a general government in the colonies, to be administered by a president-general, appointed by the crown, and by a grand council, consisting of members chosen by the representatives of the different colonies; the whole executive authority to be committed to the presidentgeneral; the legislative to the grand council and president jointly; and all laws to be approved of by the king. This plan was unanimously approved of by the commissioners for the crown and the colonies appointed to consult on the question, but its final fate was singular. It was rejected by the ministry of Great Britain as too democratical, and by every local assembly as too despotic. These verdicts were, perhaps, the best proof of its excellence, and of its having steered exactly in the middle betwixt the interests of both.

seven hundred and fourteen privates killed, out of eleven hundred who fell into the snare. All the artillery and stores, of course, were left to the enemy.

As soon as the news of the defeat, and the loss of the waggons and horses, became generally known, the owners came in a body upon Franklin for the amount of their claims, for which he had given bond, amounting to nearly L.20,000! It was with difficulty that many of these claimants were prevented from suing him, until government had time to examine into their charges and order payment; but the matter was at length satisfactorily settled.

The assembly now laid a tax, to raise money for the defence of the province, and Franklin was appointed one of the commissioners to dispose of it. He had also carried a bill through the house for establishing and disciplining a voluntary militia. To promote the association necessary to form the militia, he wrote a dialogue upon the subject, which was extensively circulated, and thought to have great effect. While the several companies in the city and country were forming and learning their exercise, the governor prevailed upon Franklin to take charge of the north-western frontier, which was infested by the enemy, and provide for the defence of the inhabitants, by raising troops, and building a line of forts. Franklin did not think himself very well qualified for the military, but was willing to be of all the service in his power. He received a commission from the governor, with full authority, and a parcel of blank commissions for officers, to be given to whom he thought fit. Five hundred and sixty men were soon raised and placed under his command.

The British government having thus rejected a proposal of internal defence in the colonies, they were soon obliged to adopt measures of another sort for their protection. Aggressive operations were again threatened by the French; and in 1754, General Braddock was dispatched from England with two regiments of regular English troops to resist them. The troops were landed at Alexandria, and marched thence to Fredericktown in Maryland, where they halted for carriages to trans-planning and marking out the fort, with a circumference port their baggage, ammunition, &c., to the frontiers. Great reluctance was manifested by the country people to supply these, and, in fact, so few were sent in, and so many other difficulties occurred, that the general was about to abandon the expedition altogether. In this dilemma he was fortunately joined by Franklin, who, aware of the necessity and importance of the expedition, asked General Braddock what recompense he would afford to the owners for the use of their waggons and horses. General Braddock referred the terms to himself; they were drawn up and accepted; and Frank-penters built within them a platform of boards all round, lin immediately published them in an advertisement, with an animated appeal from himself to the loyalty and patriotism of his countrymen. The consequence was, that, in two weeks, 150 waggons and 260 horses poured into the camp, the owners of which, however, declined the security of the British commander for compensation, and insisted on having the personal bond of Franklin. This he accordingly gave them, and even advanced several hundred pounds of his own in present payment.

The expedition accordingly set forward, and its disastrous issue must still be well remembered. Although a brave man, Braddock had far too much confidence in the prowess of his regular troops, and too much contempt for the Americans and Indians. About one hundred of the latter joined him on his march, who would have proved of the utmost use to him as guides and scouts, but he treated them so slightingly that they all left him. No appearance of the enemy was seen until the troops had penetrated far into the interior; and the first intelligence which they had of the approach of a foe, was in finding that they had fallen into an ambuscade, where they were mowed down in hundreds by invisible antagonists secreted amongst the trees and bushes. A general rout and confusion almost immediately ensued. The drivers cut their horses' traces and fled, abandoning the waggons, which also obstructed the retreat of the soldiers. The general was with difficulty brought off, severely wounded; and, out of eighty

The first place selected for the erection of a fort was Gnadenhutten, a small settlement of Moravians; and thither Franklin set out in the middle of winter, amid torrents of rain, and through almost impassable roads. Upon arriving at the village, he lost not a moment in of 455 feet; and the men were instantly set to work with their axes to cut down trees for palisades. Seeing the trees fall so fast, Franklin had the curiosity to look at his watch when two men began to cut at a pine. In six minutes they had it upon the ground, and it was fourteen inches in diameter. Each pine made three palisades, of eighteen feet long, pointed at one end. While these were preparing, other men dug a trench all round, of three feet deep, in which the palisades were to be planted. When these were set up, the carabout six feet high, for the men to stand on and fire through the loopholes. They had one swivel gun, which they mounted, and fired as soon as it was fixed, that the Indians might know they had such pieces. Thus their fort, such as it was, was finished in a week, though it rained so hard every other day that the men were almost unable to work.

"This gave me occasion to observe," says Franklin, "that when men are employed they are best contented. For on the days they worked, they were good-natured and cheerful, and, with the consciousness of having done a good day's work, they spent the evening gaily. But, on our idle days, they were mutinous and quarrelsome, finding fault with the pork and the bread, and were continually in bad humour; which put me in mind of a sea captain, whose rule it was to keep his men constantly at work; and when his mate once told him that they had done every thing, and there was nothing further to employ them about, 'Oh,' said he, make them scour the anchor.'

6

This kind of fort," he continues, "however contemptible, is a sufficient defence against Indians, who have no cannon. Finding ourselves now posted securely, and having a place to retreat to on occasion, we ventured out in parties to scour the adjacent country. We met with no Indians, but we found the places on the neighbouring hills where they had lain to watch our proceedings. There was an art in their contrivance of those places that seems worth mentioning.

It being winter, a fire was necessary for them; but a common fire, on the surface of the ground, would by its light have discovered their position at a distance; they had therefore dug holes in the ground about three feet in diameter, and somewhat deeper; we found where they had, with their hatchets, cut off the charcoal from the side of burnt logs lying in the woods. With these coals they had made small fires in the bottom of the holes; and we observed among the weeds and grass the prints of their bodies made by their lying all round, with their legs hanging down in the holes, to keep their feet warm, which with them is an essential point. This kind of fire, so managed, could not discover them either by its light, flame, sparks, or even smoke: it appeared that the number was not great, and it seems they saw we were too many to be attacked by them with a prospect of advantage.

We had for our chaplain a zealous Presbyterian minister, Mr Beatty, who complained to me that the men did not generally attend his prayers and exhortations. When they enlisted they were promised, besides pay and provisions, a gill of rum a-day, which was punctually served out to them, half in the morning and half in the evening, and I observed they were punctual in attending to receive it." Franklin advised that the rum should be distributed only just after prayers; and never were prayers more generally or more punctually

attended.

Franklin's military career was, however, a short one; for he had scarcely completed his defensive preparations, when he received a summons to attend the assembly, where his advice and assistance were found indispensable.

him for the services he had performed in England. He was also immediately re-elected to his seat in the assembly.

Upon the breaking out of the fatal disturbances in consequence of Mr Grenville's Stamp Act, Franklin had again returned to England, as agent for Pennsylvania and other states. During his residence in England, he consulted, with unremitting industry, the best interests of his native country. He was every where received with respect, on account of his reputation as a writer and philosopher. Franklin was unwearied in his efforts to bring about a reconciliation. He had frequent interviews with Lord Howe and Lord Chatham, and other distinguished English statesinen, who entertained for him the highest respect and esteem. Most of the time during his present residence in England was occupied in these vain efforts. It is well known that the first violent demonstrations against the imposition of the Stamp Act, broke out in Franklin's native place, Boston, the capital of the state of Massachussets. The governor, Hutchinson, and other functionaries, wrote to the home government, recommending the adoption of the most rigorous coercive measures, and inveighing in unmeasured terms against the leading characters of the state. By some unaccountable means, these letters fell into Franklin's hands ere they reached their destination. He instantly transmitted them back to the assembly at Massachus sets, who, enraged at the conduct of the governor, sent a petition to the king, praying for his dismissal, and Franklin was appointed to present it. As might have been expected, the petition was dismissed as "frivolous and vexatious ;" and Franklin incurred so much obloquy for his interception of the governor's dispatches (the The disputes between the proprietaries and the people, mode of which was never discovered), that he was disbefore referred to, continued to increase in 1755 and missed from his office of deputy-postmaster-general. 1756, although a war was then raging on the frontiers He still continued in England, however, and left nothing -the French having still possession of Canada. The untried to effect a reconciliation between the motherpopular assemblies insisted on the justice of taxing the country and the colonies; but finding all his endeavours proprietary estates; but the governors constantly re- unavailing, he returned to America in 1775. The day fused to assent to such a measure.

During this time, nation. In 1778, Franklin was sent as ambassador to the governor passed a law imposing a tax, in which no the court of France, where he soon brought about an discrimination was made in favour of the estates of the alliance between that nation and the North American Penn family, which were immensely large.

After long debate and deli- the definitive treaty to that effect was signed at Paris beration, a proposal was made that Franklin should per- on the 3d of September 1783, by Dr Franklin, Mr sonally engage that the proprietary estates should pay Adams, and Mr Jay, for the states, on the one hand; no more than a just proportion of the tax. This he and by Mr David Hartley, for Great Britain, on the agreed to do the proprietaries withdrew their opposi- other. Franklin continued at Paris for the two foltion, and tranquillity was once more restored to the pro-lowing years; but at last, by his own urgent request, vince. The manner in which this dispute was terminated sufficiently evinces the high confidence entertained of Franklin's honour and integrity, even by those opposed to his political views. After this, Franklin remained some time at the British court, having, besides Pennsylvania, been also appointed agent for the states of Massachussets, Maryland, and Georgia.

The French in Canada still continuing to molest and interrupt the trade of the other colonies, Franklin published his famous Canada pamphlet, in which he in a forcible manner pointed out the advantages which would result from the conquest of that province. An expedition was accordingly sent out under General Wolfe, the result of which is well known. At the treaty in 1762, France ceded Canada to Great Britain, and by her cession of Louisiana at the same time, relinquished all her possessions on the continent of America.

In the summer of 1762, Franklin returned to America, and received the thanks of the Assembly of Pennsylvania, as well for the faithful discharge of his duty to that province in particular, as for the many and important services done to America in general, during his residence in Great Britain. A compensation of L.5000, Pennsylvania currency, was likewise decreed

was recalled. Shortly after his return, he was elected president of the supreme executive council, and lent all his still perfect energies to consolidating the infant government. Age and infirmities, however, claimed their usual ascendancy; and in 1788 he retired wholly from public life.

DEATH.

Franklin's last public act-and it was one in beautiful accordance with the whole tenor of his life-was putting his signature, as president of the Anti-Slavery Society, to a memorial presented to the House of Representatives, praying them to exert the full powers intrusted to them to discourage the revolting traffic in the human species. This was on the 12th of February 1789. From this day forward, he was confined almost constantly to bed with the stone, from which he suffered the most excruciating agony. Yet, when his paroxysms of pain drew forth, as they did occasionally, an irrepressible groan, he would observe, he was afraid he did not bear his sufferings as he ought-acknowledged his grateful sense of the many blessings he had received from the Supreme Being, who had raised him from small and low beginnings to such high rank and consideration

among men, and made no doubt but his present afflictions were kindly intended to wean him from a world in which he was no longer fit to act the part assigned him. He latterly sunk into a calm lethargic state; and, on the 17th April 1790, about eleven o'clock at night, he quietly expired. He was then aged exactly eighty-four years and three months. The following epitaph, written by himself many years previous to his death, was inscribed on his tombstone:

"The Body of BENJAMIN FRANKLIN, Printer [like the cover of an old book, its contents torn out, and stript of its lettering and gilding], lies here food for worms; yet the work itself shall not be lost, for it will (as he believed) appear once more in a new and more `beautiful edition, corrected and amended by THE AUTHOR."

CHARACTER.

[ocr errors]

and use of a hundred pounds. So much in stock, briskly turned by an industrious man, produces great advantage. Remember this saying, The good paymaster is lord of another man's purse.' He that is known to pay punetually, and exactly to the time he promises, may at any time, and on any occasion, raise all the money his friends can spare. This is sometimes of great use. After industry and frugality, nothing contributes more to the raising of a young man in the world than punctuality and justice in all his dealings: therefore, never keep borrowed money an hour beyond the time you promised, lest a disappointment shut up your friend's purse for ever.

The most trifling actions that affect a man's credit are to be regarded. The sound of your hammer at five in the morning, or nine at night, heard by a creditor, makes him easy six months longer; but if he sees you at a billiard-table, or hears your voice at a tavern, when you should be at work, he sends for his money the next day; demands it before he can receive it in a lump.

It shows, besides, that you are mindful of what you owe; it makes you appear a careful as well as an honest man, and that still increases your credit.

Beware of thinking all your own that you possess, and of living accordingly. It is a mistake that many people who have credit fall into. To prevent this, keep an exact account, for some time, both of your expenses and your income. If you take the pains at first to mention particulars, it will have this good effect you will discover how wonderfully small trifling expenses mount up to large sums, and will discern what might have been, and may for the future be saved, without oecasioning any great inconvenience.

In looking back on Franklin's career, it is evident that the principal feature in his character was worldly prudence-not in the usual and selfish acceptation of the term, but that prudence, founded on true wisdom, which dictates the practice of honesty, industry, frugality, temperance, in short, all those qualities which may be classified under the name of "moral virtues"-as being the only certain means of obtaining distinction, respect, independence, and mental cheerfulness. There is no other writer who inculcates lessons of practical wisdom in a more agreeable and popular manner, and we much regret that the limits of this sheet prevent our giving many extracts illustrative of this quality. His whole conduct and writings, indeed, present the somewhat singular union of great genius with practical good sense, and of singular worldly shrewdness with the loftiest integrity of principle. The greatest worldly honours and few have attained higher-could not for a moment make him forget or deviate from the prin-words-industry and frugality; that is, waste neither ciples with which he started in life. Ever keeping before his mind his own origin and rise, he justly considered every man to be originally on a par in as far as regarded real intrinsic worth; and, equally by precept and example, contributed more, perhaps, than any individual who ever existed, to breaking down those invidious bars to eminence and success in life which the conventional habits and artificial feelings of society had theretofore interposed to the elevation of those unblessed by birth and fortune.

As the present biography must be considered as more immediately instructive to the industrious and productive portion of mankind, we shall conclude it by giving the following " Advice to a Young Tradesman, written by Franklin at the time when his industrious and frugal habits were just beginning to be rewarded with independence and worldly respect.

"Remember that time is money. He that can earn ten shillings a-day by his labour, and goes abroad, or sits idle one-half of that day, though he spends but sixpence during his diversion or idleness, ought not to reckon that the only expense; he has really spent, or rather thrown away, five shillings besides.

Remember that credit is money. If a man lets his money lie in my hands after it is due, he gives me the interest, or so much as I can make of it during that time. This amounts to a considerable sum where a man has good and large credit, and makes good use of it. Remember that money is of a prolific, generating nature. Money can beget money, and its offspring can beget more, and so on. Five shillings turned is six; turned again is seven and threepence; and so on till it becomes a hundred pounds. The more there is of it, the more it produces every turning, so that the profits rise quicker and quicker. He that kills a breeding sow, destroys all her offspring to the thousandth generation. He that murders a crown, destroys all that it might have produced, even scores of pounds.

In short, the way to wealth, if you desire it, is as plain as the way to market. It depends chiefly on two

time nor money, but make the best use of both. Without industry and frugality nothing will do, and with them every thing. He that gets all he can honestly, and saves all he gets (necessary expenses excepted), will certainly become rich-if that Being who governs the world, to whom all should look for a blessing on their honest endeavours, doth not, in his wise providence, otherwise determine."

About forty years later, after a long life of experience, he penned the following similar admonitions, entitled, "Necessary Hints to those that would be Rich":

"The use of money is all the advantage there is in having money. For six pounds a-year you may have the use of one hundred pounds, provided you are a man of known prudence and honesty. He that spends a groat a-day idly, spends idly about six pounds a-year, which is the price for the use of one hundred pounds. He that wastes idly a groat's worth of his time per day, one day with another, wastes the privilege of using one hundred pounds each year.-He that idly loses five shillings' worth of time, loses five shillings, and might as prudently throw five shillings into the sea.-He that loses five shillings, not only loses that sum, but all the advantages that might be made by turning it in dealing; which, by the time that a young man becomes old, will amount to a considerable sum of money.-Again; he that sells upon credit, asks a price for what he sells equivalent to the principal and interest of his money for the time he is to be kept out of it; therefore, he that buys upon credit, pays interest for what he buys; and he that pays ready money, might let that money out to use; so that he that possesses any thing he has bought, pays interest for the use of it. Yet, in buying goods, it is best to pay ready money, because he that sells upon credit expects to lose five per cent. by bad debts; therefore, he charges, on all he sells upon ere. dit, an advance that will make up that deficiency.Those who pay for what they buy upon credit, pay their share of this advance. He that pays ready money escapes, or may escape, that charge.

Remember that six pounds a-year is but a groat aday. For this little sum (which may be daily wasted either in time or expense, unperceived) a man of credit may, on his own security, have the constant possession | Sold also by W. S. Orr & Co., London.

PRESERVATION OF HEALTH.

should, accordingly, in all cases, be chosen for both single houses and towns. Tanks and collections of water of every kind are dangerous beneath or near a house, because, unless their contents be constantly in a state of change, which is rarely the case, their tendency is to send up exhalations of a noxious kind. A few years ago, the eldest son of an English nobleman-a youth of great promise, and who had recently become a husband and father-died of a fever which was traced to the opening of an old reservoir of water underneath the country-house in which he dwelt.*

A HUMAN being, supposing him to be soundly constituted at first, will continue in health till he reaches old age, provided that certain conditions are observed, and no injurious accident shall befall. This is a proposition so well supported by an extensive observation of facts, that it may be regarded as established. It becomes, of course, important to ascertain what are the conditions essential to health, in order that, by their observance, we may preserve for ourselves what is justly esteemed as the greatest of earthly blessings, and dwell for our naturally appointed time upon the earth. A general acquaintance with these conditions may be easily attained by all, and to pay them obedience is much more within the power of individuals than is generally sup-regulated towns-ill-managed drains-collections of posed.

The leading conditions essential to health may be thus enumerated:-1. A constant supply of pure air; 2. A sufficiency of nourishing food, rightly taken; 3. Cleanliness; 4. A sufficiency of exercise to the various organs of the system; 5. A right temperature; 6. A sufficiency of cheerful and innocent enjoyments; and, 7. Exemption from harassing cares.

AIR.

The common air is a fluid composed mainly of two gases, in certain proportions; namely, oxygen as 20 and nitrogen as 80 parts in a hundred, with a very minute addition of carbonic acid gas. Such is air in its pure and right state, and such is the state in which we require it for respiration. When it is loaded with any admixture of a different kind, or its natural proportions are in any way deranged, it cannot be breathed without producing injurious results. We also require what is apt to appear a large quantity of this element of healthy existence. The lungs of a healthy full-grown man will inhale the bulk of twenty cubic inches at every inspiration, and he will use no less than fifty-seven hogsheads in twenty-four hours.

Now, there are various circumstances which tend to surround us at times with vitiated air, and which must accordingly be guarded against. That first calling for attention is the miasma or noxious quality imparted to the air in certain districts by stagnant water and decaying vegetable matter. It is now generally acknowledged that this noxious quality is in reality a subtle poison, which acts on the human system through the medium of the lungs, producing fevers and other epidemics. A noted instance of its acting on a great scale is presented in the Campagna di Roma, where a large surface is retained in a marshy state. The air arising from that territory at certain seasons of the year, obliges the inhabitants of the adjacent districts of the city to desert their homes, in order to escape its pernicious influence. All marshes, and low damp grounds of every kind, produce more or less miasma, and it is consequently dangerous to live upon or near them. Slightly elevated ground

Putrid matter of all kinds is another conspicuous source of noxious effluvia. The filth collected in ill

decaying animal substances, placed too near or within private dwellings-are notable for their effects in vitiating the atmosphere, and generating disease in those exposed to them. In this case, also, it is a poison diffused abroad through the air which acts so injuriously on the human frame. This was probably the main cause of the plagues which visited European cities during the middle ages. In those days there were no adequate provisions for cleaning cities, and the consequence was, that large collections of filth were accumulated. The noxious air diffused by these means through the narrow streets and confined dwellings would tend to the most fatal effects. In old drains there is generated a gas (sulphureted hydrogen), which is calculated to produce dreadful consequences amongst those exposed to it. It has lately been discovered, that it is the presence of this gas in the sea near the eastern coast of tropical Africa, which causes the peculiar unhealthiness of that region. It is ascertained that small animals, such as birds, die, when the air they breathe contains one fifteen-hundredth part of sulphureted bydrogen, and that an infusion six times greater will kill a horse. It follows, that we can scarcely attach too much importance to measures for cleaning cities and improving drains. There are as yet no large towns in Britain kept in a state so clean as is desirable for the health of their inhabitants; and the metropolis itself is amongst those which are most defective in this respect.

The human subject tends to vitiate the atmosphere for itself, by the effect which it produces on the air which it breathes. Our breath, when we draw it in, consists of the ingredients formerly mentioned; but it is in a very different state when we part with it. On passing into our lungs, the oxygen, forming the lesser ingredient, enters into combination with the carbon of the venous blood (or blood which has already performed its round through the body); in this process, about two-fifths of the oxygen is abstracted and sent into the blood, only the remaining three-fifths being expired, along with the nitrogen nearly as it was before. * Viscount Milton, son of the present Earl Fitzwilliam, was the person here alluded to.

flue-for example, that of the kitchen, which is rarely cold. Thus there might be a constant passing of fresh air into and through every room of a large house, so that it would be at all times as healthy in this respect as the open fields. At the same time, the supply might, by means of graduated valves, be regulated to any degree which might be deemed agreeable.

In place of the oxygen consumed, there is expired an | tube, the extremity of which passes into some active equal volume of carbonic acid gas, such gas being a result of the process of combination just alluded to. Now, carbonic acid gas, in a larger proportion than that in which it is found in the atmosphere, is noxious. The volume of it expired by the lungs, if free to mingle with the air at large, will do no harm; but, if breathed out into a close room, it will render the air unfit for being again breathed. Suppose an individual to be shut up in an air-tight box: each breath he emits throws a certain quantity of carbonic acid gas into the air filling the box; the air is thus vitiated, and every successive inspiration is composed of worse and worse materials, till at length the oxygen is so much exhausted, that it is insufficient for the support of life. He would then be sensible of a great difficulty in breathing, and in a little time longer he would die.

Most rooms in which human beings live are not strictly close. The chimney and the chinks of the door and windows generally allow of a communication to a certain extent with the outer air, so that it rarely happens that great immediate inconvenience is experienced in ordinary apartments from want of fresh air. But it is at the same time quite certain that, in all ordinary apartments where human beings are assembled, the air unavoidably becomes considerably vitiated, for in such a situation there cannot be a sufficiently ready or copious supply of oxygen to make up for that which has been consumed, and the carbonic acid gas will be constantly accumulating. This is particularly the case in bedrooms, and in theatres, churches, and schools. An extreme case was that of the celebrated Black Hole of Calcutta, where a hundred and fortysix persons were confined for a night in a room eighteen feet square with two small windows. Here the oxygen scarcely sufficient for the healthy supply of one person, was called upon to support a large number. The unfortunate prisoners found themselves in a state of unheard-of suffering, and in the morning all were dead but twenty-three, some of whom afterwards sunk under putrid fever brought on by breathing so long a tainted atmosphere.

FOOD.

The second requisite for the preservation of health is a sufficiency of nutritious food.

Organic bodies, in which are included vegetables as well as animals, are constituted upon the principle of a continual waste of substance supplied by continualnutri

tion.

The Nutritive System of animals, from apparently the humblest of these to the highest, comprehends an alimentary tube or cavity, into which food is received, and from which, after undergoing certain changes, it is diffused by means of smaller vessels throughout the whole structure. In the form of this tube, and in the other apparatus connected with the taking of food, there are, in different animals, varieties of structure, all of which are respectively in conformity with peculiarities in the quality and amount of food which the particular animals are designed to take. The harmony to be ob served in these arrangements is remarkably significant of that Creative Design to be traced in all things.

MAN DESIGNED TO LIVE ON A MIXED DIET.

Some animals are formed to live upon vegetable substances alone; others are calculated to live upon the flesh of other animals. Herbivorous animals, as the former are called, have generally a long and compli cated alimentary tube, because the nutritious part of such food, being comparatively small in proportion to the whole bulk, requires a greater space in which to be extracted and absorbed into the system. The sheep, for example, has a series of intestines twenty-seven times the length of its body. For the opposite reasons,

tribe of quadrupeds, and the rapacious birds, have generally a short intestinal canal The former class of animals are furnished with teeth, calculated by their broad and flat surfaces, as well as by the lateral movement of the jaws in which they are set, to mince down the herbage and grain eaten by them. But the carnivorous animals, with wide-opening jaws, have long and sharp fangs to seize and tear their prey. These peculiarities of structure mark sufficiently the designs of nature with respect to the kinds of food required by the two different classes of animals for their support.

Although the vitiation of the air in ordinary apart-carnivorous or flesh-devouring animals, as the feline ments and places of public assembly does not generally excite much attention, it nevertheless exercises a certain unfavourable influence on health in all the degrees in which it exists. Perhaps it is in bedrooms that most harm is done. These are generally smaller than other rooms, and they are usually kept close during the whole night. The result of sleeping in such a room is very injurious. A common fire, from the draught which it produces, is very serviceable in ventilating rooms, but it is at best a defective means of doing so. The draught which it creates generally sweeps along near the floor between the door and the fire, leaving all above the level of the chimney-piece unpurified. Yet scarcely any other arrangement is any where made for the purpose of changing the air in ordinary rooms. To open the window is a plan occasionally resorted to, but it is not always agreeable in our climate, and sometimes it produces bad consequences of a different kind.

It would nevertheless be easy to produce an effective draught from any room in which a fire is kept. It is only necessary to make an aperture into the flue, near the ceiling of the room, and insert therein a tin tube, with a valve at the exterior, capable of opening inwards, but closing when at rest or when a draught is sent the contrary way. The draught produced by the fire in the flue would cause a constant flow of air out of the upper part of the room (where most vitiated); and the valve would be an effectual protection against back-smoke, should there be the least tendency to it. This plan is adopted in Buckingham Palace. It could be applied to any existing house at a mere trifle of

[blocks in formation]

The human intestinal canal being of medium length, and the human teeth being a mixture of the two kinds, it necessarily follows that man was designed to eat both vegetable and animal food. As no animal can live agreeably or healthily except in conformity with the laws of its constitution, it follows that man will not thrive unless with a mixture of animal and vegetable food. The followers of Pythagoras argued, from the cruelty of putting animals to death, that it was proper to live on vegetables alone; and many eccentric persons of modern times have acted upon this rule.

On the other hand, we cannot dispense with vegetable food, without injurious conséquences. In that case, we place in a medium alimentary canal a kind of food which is calculated for a short one, thus violating an arrangement of the most important nature. A balance between the two kinds of food is what we should observe, if we would desire to live a natural and consequently healthy life.
