Dr. Chisholm acknowledges that he lost one in twelve of all the patients he attended in the fever of Grenada. His principal remedy was a salivation. I shall hereafter show the inferiority of this single mode of depleting, to a combination of it with bleeding and purging. In Philadelphia and Baltimore, where bleeding, purging, and salivation were used in due time, and after the manner that has been described, not more than one in fifty died of the yellow fever. It is probable that greater certainty and success in the treatment of this disease will not easily be attained, for idiosyncracy, and habits of intemperance which resist or divert the operation of the most proper remedies, a dread of the lancet, or the delay of an hour in the use of it, the partial application of that or any other remedy, the unexpected recurrence of a paroxysm of fever in the middle of the night, or the clandestine exhibition of wine or laudanum by friends or neighbours, often defeat the best concerted plans of cure by a physician. Heaven in this, as in other instances, kindly limits human power and benevolence, that in all situations man may remember his dependence upon the power and goodness of his Creator. AN ACCOUNT OF SPORADIC CASES OF _BILIOUS YELLOW FEVER_, IN PHILADELPHIA, IN THE YEARS 1795 AND 1796. In my account of the yellow fever, as it appeared in Philadelphia in the year 1794, I took notice of several cases of it which occurred in the spring of the year 1795. Before I proceed to deliver the history of this disease as it appeared in 1797, I shall mention the diseases and state of the weather which occurred during the remaining part of the year 1795, and the whole of the year 1796. This detail of facts, apparently uninteresting to the reader in the present state of our knowledge of epidemics, may possibly lead to principles at a future day. The month in of April, 1795, was wet and cold. All the diseases of this month partook of the inflammatory character of the preceding winter and autumn, except the measles, which were unusually mild. The weather in May was alternately wet, cool, and warm. A few cases of malignant fever occurred this month, but with moderate symptoms. In June the weather was cool and pleasant. The measles put on more inflammatory symptoms than in the preceding months. I had two cases of mania under my care this month, and one of rheumatism, which were attended with intermissions and exacerbations every other day.
