them during the pestilential season, the “puantes vapeurs de la mer”, as Sir John expresses himself, “ qui faient bondir le cœur la première fois qu'on le sent.” These on the African coast are impregnated from the impenetrable mangrove swamps of the interior of Guinea, and on the Persian, from the saline and sulphurous exhalations of the several adjoining islands which the winds of the season pass over in their periodical sweep: and the copious disengagement of hydrogene, whose presence the intolerable stench seems to indicate, will account in no small degree for the deficiency of living power, which so peculiarly distinguishes the malignant remittent in these quarters. In the latter region, indeed, some such debilitating influence seems to operate habitually: for the ingenious author thus quoted adds, that “the nations carry in their complexion and constitution the proofs of their malignant atmosphere, being yellow and ghastly from the age of twenty-one, and decrepid at thirty.” Of the destructive power of such vapours, we

have sufficient proof from what occurs on the coast of Coast of Batavia, and the islands that immediately surround it: Batavia.

The disease under those circumstances often begins regularly as a single tertian; and two, and sometimes three revolutions pass over without giving any alarm to ordinary observers : but at one or other of the above periods, a paroxysm commences with coma, stupor, and suspension of functions, threatening immediate destruction : or, as often happens, the energy of action becomes less and less distinct in every succeeding paroxysm; the skin becomes dry, or damp and greasy, the powers of life are overwhelmed, the pulse contracts itself, or becomes apparently weaker and weaker under the use of bark, wine, and the strongest stimulants of the materia medica.”* His second form of the Andalusian fever of 1820, is precisely to the same effect t.

place, “ that typhous infection does exist, perhaps does originate within the tropics. How fraught with mischief therefore is that theoretical notion, that such infection cannot exist, cannot originate, and cannot be propagated in hot climates. Let the young and unexperienced practitioner guard himself against it; and be prepared for it when he meets it.”+

Dr. Chisholm offers a variety of examples in proof of this assertion, to several of which he had been an eyewitness, especially to that which is so well known to have

broken out in the unfortunate attempt to colonize the isBulam fe land of Bulam in the spring of 1793, and which gave

rise to the fever of this name, so strikingly characterized by its asthenic signs. He has noticed others also, of nearly equal demonstration, extracted from the reports communicated to the Army Medical Board of our own

country. But, perhaps, none offer more striking proofs Edam re

the marks of an extreme debility were often peculiarly impressive from the first. The patient with little previous notice, was seized with giddiness and cold chills, great sense of weakness, pain over the orbits, and in the epigastrium, together with vomiting. He frequently fell down and was insensible during the paroxysm, his body covered with a cold clammy sweat, except the pit of the stomach, which always felt hot to the palm of the hand; the pulse was small and quick; great torpor in the intestinal canal ; the pupil dilated and incontractile: great despondency at first, then low delirium or insensibility to danger. The patients, while on the island, were carried off in eighteen, twenty-four, thirty, or forty hours :

The treatment has here varied as much as in yellow Medical fever; in truth it ought to vary—not indeed according to varies and preconceived and general hypotheses, whose only va ought to

vary. riance consists in fighting general rules against general rules, but in modifying the plan, whatever it may consist in, to the peculiar case.

Bleeding, however, must never form a part of the general practice, how necessary soever it may be in particular instances where atonic congestion may oppress the head or any other large organ. And even in such instances it will generally be found more expedient to employ calomel in large and repeated doses than the lancet, unless we see the patient at the very opening of the disease. Under either practice, the bowels must be opened and kept open by active purgatives; since from the general disturbance of the functionary balance, there is violent action in the abdominal viscera, while the vessels on the surface are entirely torpid. To restore this balance should be our uniform effort: and hence in conjunction with the above nothing bids fairer, or has in fact been found more successful, than the use of warm diaphoretics with opium. Cold water as a beverage, or in the form of injection, has also proved a highly refreshing tonic; frequent potations of old hock still more so. The bark is a doubtful remedy, for it often sits uneasy on the stomach and is rejected. It has hence fallen into undeserved disrepute. When, however, it harmonizes with the stomach, and is retained without oppression, it is entitled to all the praise that has been bestowed on it by former writers, and cannot be given too freely.
