Dr. Musgrave's statement seems to oppose this assertion, for he distinctly tells us that "blood-letting in both forms is our sheet-anchor; the only pillar on which we can securely rest any hope of extensive success." The Antigua fever seems to have exhibited great severity in most instances, and hence called for a courageous course of practice with perhaps few exceptions. Yet the following paragraph proves that GEN. III. SPEC. II. B. E. malignus flavus. Yellow fever.

There can be no doubt, however, of its being highly advantageous, in a great multitude of cases, and of genately used. neral benefit in various forms of this destructive epidemy. For whether we contemplate the fever as local or unrestrained, as consisting in violent universal excitement, or, according to M. Broussais, in an inflammation of the mucous membrane of the stomach or duodenum irritating the bile-ducts, and the liver itself by sympathy; whether as threatening congestion to any of the larger organs, or actually accompanying congestion ; there is no medicine which, primâ facie, affords a better prospect of relief than mercury, from its general action on the excernent system, as well as its specific action on the intestinal canal, and the salivary glands. It must, however, be admitted that it is only under a particular condition and tone of the vascular frame, that it can at SPEC. II. Yellow fever.

In the case of ENTONIC or strong vascular action, it is necessary first of all to lower, and in the case of ATONIC or weak vascular action, to raise the living power to the proper standard before ptyalism can be obtained, which is the grand test of its having taken effect: and hence, to accomplish the former, bleeding, purgatives and cold affusion, must be first called upon to exercise their respective powers; and in the latter case, tonics and cordials; upon which last ground, Swediaur tells us that the most efficacious plan of treatment consists in giving calomel and columba, in doses of thirty-five grains each, five or six times a day*. It is truly said, indeed, by the advocates for mercury, that such other remedies are all valuable adjuvants; and this is so far from being denied by those who are hostile to the use of mercury, that they affirm, on the contrary, that the benefit ascribed to this medicine, when it has once obtained a sway over the system, ought rather to be attributed to these adjuvants themselves; which would have proved still more beneficial, had they been left to their own power and intention alone.

It would seem that DEBILITY AND THE PLETHORIC SYSTEM, ARE EQUALLY INIMICAL TO THE SPECIFIC MERCURIAL ACTION. If the patient is fortunately invigorated sufficiently to give the mercury influence, and BEFORE ANY ORGAN ESSENTIAL TO LIFE IS INJUred, by the strictest nursing and attention afterwards the recovery is almost certain, all morbid action yielding from the moment ptyalism is brought on.' Bancroft. Jackson. Even in cases, however, in which the mercurial action is fortunately excited, the same intelligent writer tells us that he has frequently met with a very serious evil resulting from the mercury itself; for such, says he, is at times the profusion of the ptyalism when once induced, that the most disagreeable consequences succeed, and the convalescence is long and precarious; on which account he laments that we have no criterion to determine how far we may proceed with the mercurial process, and when we ought to stop. Dr. Bancroft advances much farther than this, and asserts that not only has the salivation retarded the convalescence, and produced very troublesome affections of the tongue, mouth and throat, with other ill consequences, thus acknowledged by its advocates, but that the salivators, even when they have been free from these evils, have not been more successful than other practitioners; and he particularly alludes to the admission of Dr. Rush, who was not unfriendly to the mercurial mode of treatment, that "in the City Hospital (of Philadelphia), when bleeding was sparingly used, and the physicians depended chiefly upon salivation, MORE THAN ONE-HALF DIED of all the patients who were admitted."+ For like reasons Dr. Jackson speaks with as little satisfaction of the same practice, not only upon his own experience but even upon that of Dr. Chisholm himself. Alluding to the high recommendation of mercury by the latter, he observes, "the detail of his testimonies * Edin. Med. and Surg Journ. Vol. xi.

Further, it is a common observation that, where salivation actually takes place in continued fevers, it seldom shows itself till the violence of the symptoms has evidently abated: hence a suggestion arises that the appearance of salivation is only an indication of the departure of disease :-no proof exists that the operation of the mercury is the cause of this departure. Such are the remarks which occurred in reviewing different modes of treatment in the hospitals of St. Domingo; to which it will not be superfluous to add an experiment made at the Mole in August 1796 by Mr. Lind, Surgeon to Jamaica. Out of fifteen cases of fever put under the care of Mr. Lind, on the first day of the disease and treated with the utmost attention, five died; in three of whom salivation actually took place; five recovered, in whom no salivation took place; in the other five, who also recovered, salivation was evidently established; but, as is usual, not till the violence of the symptoms had begun to abate. Out of four who were put under his care on the second day of the disease, no one died; but one only was affected by the mercury; one brought to the hospital on the third day of the illness, died: mercury was employed, but no salivation took place; one, on the fourth, likewise died, without marks of salivation; one, on the fifth-the salivation was established, but the disease proved fatal. In none of the above cases were less than ten drachms, and in most not less than two ounces of strong mercurial ointment rubbed into the legs and thighs, with the employment of all other means which seemed calculated to promote the expected effect."* The question, therefore, to say the least of it, is still Hence the open; and, admitting all that can be said in favour of question still History and Cure of Fever, Part. 1.
