The Subtil Medium proved: or that wonderful Power of Na

fure, so long ago conjetured by the most ancient and remarkable Philosophers, which they called, sometimes Æther, but oftener Elementary Fire, verified. Shewing, that all the distinguishing and effential Qualities ascribed to Æther, by them, and the most eminent modern Philosophers, are to be found in Electrical Fire, and that too, in the utmost degree of Perfection. Giving an Account, not only of the Progress, and several Gradations of Ele£tricity, from those ancient Times to the present, but also accounting, first, for the natural Difference of Electrical, and Non-Electrical Bodies. Secondly, Mhewing the Source, or main Spring, from whence the Electri Matter proceeds. Thirdly, its various Ujes in the Animal Economy, particularly when applied to Maladies and Diforders incident to the human Body. Illuftrated by a Variety of known Feets. Fourthly, the Method of applying it in each particular Cafe. And, iasily, the several Objections brought against it accounted for, and answered. By R. Lovett, of the Cathedral Church of Worcester. 8vo. 2 s. Hinton.

R. Lovett has saved us the trouble of telling the Reader

what he may expect to meet with in this pamphlet, the above title being a coinpendious Epitome of the whole performance. It will also be sufficient to apprife him, that whatever discoveries may be contained in it, they are not delivered in a very elegant manner. Our Author has, in his Preface, made an apology for this, and candidiy owns, he has been

unhappily deprived of those acquired abilitie; of polite edu<cation, &c.' And adds, that, therefore, whatever can

be plainly and clearly made appear, by one in such a situa• tion, will be allowed to be the effect of undisguised truth

only, as depending principally on facts. But the want of literary accomplishments is not his only defect; for tho'he seems to have delivered his sentiments with candour and fincerity, yet, at the same time, it appears, that he is a stranger REV. Dec, 1756

to several of the common principles of the Newtonian Philosophy, and, consequently, but indifferently qualified to acçount for the many surprising Phænomena of Electricity. But notwithstanding this, his book may, at least, be of as much advantage to Society as many others that are written in a more fcientifical, and more elegant manner; the removing those distempers to which human nature is subject, being of infinitely greater consequence than many of our most refined philofophical speculations. Of this application of Electricity, Mr. Lovett has treated very fully; enumerating the cautions necessary to be observed, in order to ren der the Électrical Shocks useful; obviating the several objections made to the medicinal uses of Electricity, and accounting for the miscarriage of the several attempts, of that kind, made by others. The following instances will fhew what success Mr. Lovett has had in curing diseases by. Electricity; and we could wish they would excite others to make experiments of the same kind, that it might be finally determined, whether Electricity may, or may not be rendered useful in medicinal intentions.

• A young Lady was very much afflicted with fits, for near seven years, which seized her without giving any warning, and threw her flat on her face; for which reason it gerous to go near the fire, or even walk abroad by herself;

notwithstanding the scarce ever, excepting once, continued ' in that insensible state so long as a minute, and oftentimes

not half so long. • Their returns were very frequent ; sometimes twice in a day; tho' fometimes, perhaps, after beginning with a fresh medicine, she would find some relief; but nothing could be found which was likely to prove an absolute cure, till Electricity was advised, and complied with : what rendered the cure the more difficult, was a very great coldness in her feet; and physicians were of opinion, that the fits would not be calily conquered, except the coldness of the feet could be fuit removed : this I did not know till afterwards; but as she told me it sometimes seemed to begin in her stomach, I was not much at a loss to know how to convey the fire through both stomach and head at the same time; for, whatever be the part affected, and I have a desire to pass the fire thro' that particular part, it is only to form a circuit, as in the manner described by Experiment the fourth, and to cause that particular part to make a part of the circuit, and it is done : and since it is equal, by the fame experiment, whether the circuit be long or short, the most eligible way must

and by that means so intimidate her, as to prevent her cum

• be, to have her ftand upon the wire or chain coming from - the leaden coat of the condensing-phial, and then to com$ pleat the circuit, by laying another wire to any particular

part of her head; by which means the fire will be conveyed sto that particular part of it; for as the line of direction of

the fire, is always the shortest possible, by always taking the nearest way, as is evident by that experiinent, it may be

guided to a very great exactness: this being the method that

was taken, and the fire going thro' the feet, as well as the < ftomach and head, all seemed to receive an equal share of «the benefit ; and a compleat cure was effected, both of the <fits, and coldness of the feet; and both appearing to be con quered at the same time.

The operation was shocks only; and the Subtile Medium performed the circuits from the fole of the feet, through the crown of the head. X A young Gentlewoman of the parish of Clifton, about

ten miles from Worcester, some time after being recovered s of a fever, was feized with violent hyfterics; the effects of

which were so bad, as very soon to deprive her of both memory and understanding; and so continued for a considerCable time, notwithstanding the best advice of two eminent * physicians.

In this melancholy state she was brought to Worcester, to try the effect of Electricity : I told the person who brought her, it would be necessary to perform the operation

first, in a very light manner, left it should starile her, ing again: bur fhe replied, there was no danger of that, 6 for the could not remember half an hour to an end.

As the head was the part affected, I guided the fire " chiefly to that part, in as plentiful a manner as I well 6 could, and caused it to pass quite through, several times « each day, fo long as the staid in town, which, tho' scarce

a week, yet it seemed to have the desired effect; for, altho ( before she came to Worcester, she could not remember half

an hour to an end, yet, soon after her return home, the could remember the most remarkable things she saw done in • Worcester ; and not only her memory, but her understand. • ing also, returned, and the very soon became perfectly well.

• The operation was fometimes fhocks, fometimes draw<ing off sparks from the head.

Mr. Perkins, Surveyor of the toads, a year or two ago, • had a flight touch of what he thought a palfey, or fomething near akin to it; for, all on a sudden, his arm dropO. 2

* ped down, as effectually as in any paralytic stroke; but, by rubbing it, the use of it was again foon restored. « The same day' he had another; and in some little time after he had a third ;' which still, after it had been well rub( bed and chaffed for a time, became fo well again, as to • have the use of it, particularly at the upper and middle joint; & but the lower part of it was by no means fo strong as before,

nor could he have wrote his name, if he might have gained + the Indies by doing it: after this he had a desire to try the effect of the Electric Shock; which relieved him so effec

tually, as that he was very foon perfectly well again. The • operation was fhocks in the arm.

The same person had lately a much worse stroke of the fame kind; all the right fide was so affected, that he could

not walk without the affiftance of two to support him : • when it first happened he was out of town, fo that it was

two or three days before he could apply for help again the fame way. After he had made use of Electricity two or three times, he was able to walk with the support of one only; and, in a fortnight, or three weeks, without any one to affift him; and soon became well again. • The operation was performed thus-First-standing with his right foot on the connecting-line, coming from the condensing phial. Then, at bringing a finger of the right-hand to the apparatus, the shock was given, and the circuit of Æther continued from the foot, the nearest way thro' the body, to the arm, and each finger: this was several times repeated.'

F Experience be the sureft guide to Wisdom, and if all Sci

ences arile from the contemplation of Nature, as most certainly they do, the progress of Knowlege, confidering how limited the life, the powers, and the capacities of men are, must needs be very flow, and would be also very imperfect, were individuals left entirely to their own researches, with'out means of improving one another by a communication and comparison of discoveries and ob ervations. And altho' we

cannos

cannot boast of abilities adequate to a thorough comprehension of Nature; yet, by the proportion of time allotted us, by the faculties with which we are naturally invested, by the means of communication we enjoy, one with another, whilft alive, and of lettered converse with the dead, we have reafon to be very thankful, that our powers are suited to our situation, and capable of extending knowlege, fo far, at least, as to be not only fufficient for our well-being, but conducive to

our amusement.wr, - » The proper study of mankind, is man; says a great Poet, in one of his most philosophical works : and true it is, that a right conception of human Nature, so as to comprehend not only wherein its dignity consists, but also its depravity, is that basis on which alone we can raise any juft scheme of Politics, Morality, or Religion. Man, or Human Nature, as an object of contemplation, must be that subject, which, above all others, deserves our utmost attention.

On other subjects we are left to our own observations, and the experiments made by others; and have it in our power, by renewing our own efforts, and reiterating theirs, to ascer

tain the degrees of our knowlege, correct mistakes, separate * the certain from the uncertain, and thus gradually enlarge the

boundaries of science. But on this fubject, and this alone, We have not only all the advantages which can arise from our own'application, and the affiftance of others, but such a confciousness of the subject itfelf, and such a connection and intimacy with it, as places it not only nearer us, but in a stronger and fuller light, than any other.

True it is, however, that we cannot with historical facts, as we may with philosophical enquiries, recal the events, and put them again to the test: but we need not, therefore, be imposed upon by them. We can, and where no divine authority interposes to the contrary, we furely ought, to reduce all human evidence to the standard of probability. We know the extent of human power, its adventitious aids, the maniers of men, the course of providence, the turns and accidents that may happen; all these we know, not only by our own experience in present times, but by the concurrent report of the best and wifest men, who have transmitted to us the history of former ages; and we find human abilities, and propensities, so much the faine, and Providence fo regular and uniform, that all accounts too much magnifying the one, or diversifying the other, may justly appear romantic and fabulous; especially when
