Pure air by a ventilation of the atmosphere, is however a more powerful remedial agent than all the rest put together; and to this position I apprehend every class of writers will accede, how much soever they may differ upon other points. The Army Medical Board is

We cannot wonder therefore at beholding this able officer, anxious, in his report for 1823, that the same plan should be extended to other places, and adopted in other diseases. “ In cases of sickness,” Hartley's

encomium. says he, “ and especially in yellow fever, I feel convinced in my own mind, that nothing could prove so beneficial in checking the ravages of this disease as separating the troops ; and particularly by removing them to some distant dry field from the locality of the attack. Nothing could more immediately substantiate the advantages of removing and encamping a body of men, than the result in the Pyramus's crew.” In Barbadoes, where, as I have just observed, the Exempli

fied at Barsame improvement has obtained a footing, the mortality for the last two years is almost incredibly abated. I have examined the tables subjoined to the annual reports in the office of the Army Medical Board, and have found that, from having been upon an average of seven years, about one in twenty-one of the sick list, in 1822, the mortality was only one in twenty-four; and in 1823,

several other important regulations, for which we are equally indebted to the vigilance and the judgement of the Army Medical Board, may have contributed to this salutary change, but the greater part of it is still, perhaps, to be ascribed to the new plan of encamping. I cannot give a better description of the adjuvant regulations I am now referring to, than by adopting the words of Mr. Tegart, an enlightened inspector of hospitals at Barbadoes, who, in his manuscript report for 1823, thus enumerates them, and at the same time confirms the

year" alluding to 1822, or the preceding, “ was so comparatively small with former ones, that I hardly hoped to send so favourable a one again. This return, however, exceeds greatly any hopes I could have anticipated; being not one half the average amount of the preceding six years : and not a sixth part of the yearly loss sustained in the fourteen years antecedent to those. There are many reasons for this favourable change; the men are better clothed, better fed, and better looked after by their officers; there are many local improvements in the vicinity of the barracks, which formerly were not much attended to: such as draining swampy and marsh ground; clearing away brush-wood and long grass, which harboured moisture, and emitted, at certain seasons, noxious exhalations, producing fever and other diseases, the treatment of which was very different from that of the present day. I believe most sincerely that we are also indebted for the favourable comparison in the scale of mortality to the improved education of medical men, to the discoveries in the various branches of medical science, and to the rationale of medical practice.” The writer of


this work cannot avoid adding his conscientious assent to Gen. III. the correctness of these views.

trico-ingastrico-nervosa. In Hippocrates it is briefly described Hammatoria as a fever, characterised by extreme heat, violent thirst, of Frank. a rough and black tongue, complexion inclined to yellowish, saliva bilious. There is commonly an acute aching in the head, nausea, great anxiety of the præcordia, with frequently a gnawing pain at the stomach. The bowels are unusually costive, particularly at the commencement of the disease. The tongue, mouth, nostrils, and, indeed, the whole surface of the body are parched and fiery-hot, whence, indeed, the Greek name for the disease; the pulse is full and strong; the voice hoarse: the breathing short and quick, with sometimes a slight cough, and occasionally delirium. It chiefly attacks the young and the vigorous, who Causés

And, if so, it affords us a proof that under certain modifications, febrile miasm issuing from this source may, as I have already suggested, produce a caumatic or inflammatory, as well as a synochous or typhous tendency, in constitutions predisposed to this

the stomach is generally less irritable, and will bear vomiting with advantage: and, in the second stage, the chilliness which, in the yellow fever, is merely accompanied with horripilation, and is a mischievous symptom, in the causus, is accompanied with a smart rigor, which often terminates in a copious and salutary sweat. The process moreover, in the causus, generally lasts only four days, and is terminated, when left to itself, by a critical diaphoresis, vomiting, diarrhæa, or nasal hemorrhage ; but if the fever be not carried off in this way, it com
