Generally speaking, it will be best to bleed in an erect position, for the sensorial excitement, which is what we are chiefly to aim at, is best cut down by syncope, which an erect position will soonest induce; and we may, hence, save the expense of several subsequent bleedings.

Dr. Pym speaks with a very just discrimination upon this subject, in observing that while the Bulam fever, or the disease in its most violent attack, is relieved by free venesection, the yellow fever, more properly so called from the brighter hue on the surface, or, in other words, that which is slighter in its incursion, will not often endure the lancet. 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.

With equal success we have in several cases renewed the bleeding up to the third, and even the fourth time; but, generally speaking, those which require such reiterated evacuation evince an obstinacy NOT LIKELY TO ADMIT OF A FAVOURABLE RESULT UNDER ANY MODE OF TREATMENT.

It only needs to be observed further that the bowels were emptied, as they ought to be, by calomel or jalap, or some other active purgative; the head was shaven, and cold ablution preferred ordinarily to cold affusion, because of the fatigue endured under the latter. Bark was then instantly given, and, where the stomach would bear it, in the powder. Mercury, with a view of exciting salivation, was seldom tried, and not relied upon.

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 is truly said, indeed, by the advo. cates for mercury, that such other remedies are all valuable adjuvants; and this is so far from being denied by to which

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 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

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
