cured nineteen out of twenty of all the soldiers whom he attended, by copious bleeding, provided it was performed within six hours after the attack of the fever. Beyond that period, it mitigated its force, but seldom cured. The quantity of blood drawn by the doctor, in this early stage of the disease, was always from twenty to thirty ounces. I have said the yellow fever of 1797 was more malignant than the fevers of 1793 and 1794. Its resemblance to the yellow fever in the West-Indies, in not yielding to bleeding after the first day, is a proof of this assertion. I was struck, during my attendance upon this fever, in observing the analogy between its _mixed_ form and the malignant state of the small-pox. The fever, in both, continues for three or four days without any remission. They both have a second stage, in which death usually takes place, if the diseases be left to themselves. By means of copious bleeding in their first, they are generally deprived of their malignity and mortality in their second stage. This remark, so trite in the small-pox, has been less attended to in the yellow fever. The bleeding in the first stage of this disease does not, it is true, destroy it altogether, any more than it destroys an eruption in the second stage of the small-pox, but it weakens it in such a manner that the patient passes through its second stage without pain or danger, and with no other aid from medicine than what is commonly derived from good nursing, proper aliment, and a little gently opening physic. It is common with those practitioners who object to bleeding in the yellow fever, to admit it occasionally in _robust_ habits. This rule leads to great error in practice. From the weak action of predisposing, or exciting causes, the disease often exists in a feeble state in such habits, while from the protracted or violent operation of the same causes, it appears in great force in persons of delicate constitutions. A physician, therefore, in prescribing for a patient in this fever, should forget the natural strength of his muscles, and accommodate the loss of blood wholly to the morbid strength of his disease. The quantity of blood drawn in this fever was always proportioned to its violence. I cured many by a single bleeding. A few required the loss of upwards of a hundred ounces of blood to cure them. The persons from whom that large quantity of blood was taken, were, Messieurs Andrew Brown, Horace Hall, George Cummins, J. Ramsay, and George Eyre. But I was not singular in the liberal and frequent use of the lancet. The following physicians drew the quantities of blood annexed to their respective names from the following persons, viz. Dr. Dewees 176 ounces from Dr. Physick, Dr. Griffitts 110 Mr. S. Thomson, Dr. Stewart 106 Mrs. M'Phail, Dr. Cooper 150 Mr. David Evans, Dr. Gillespie 103 himself.
