The last mode was by far the most successful. It is worthy of notice, that the business and reputation of the physicians, during this epidemic, were in the inverse ratio of their success. The number of deaths by it amounted to between three and four thousand, among whom were three physicians, and two students of medicine. Its mortality was nearly as great as it was in 1793, and yet the number of people who were affected by it was four times as great in 1793 as it was in 1798, for, in the latter year, the city was deserted by nearly all its inhabitants. The cause of this disproportion of deaths to the number who were sick, was owing to the liberal and general use of the lancet in 1793, and to the publications in 1797 having excited general fears and prejudices against it in 1798. Such was the influence of these publications, that many persons who had recovered from this fever in the two former years, by the use of depleting remedies, deserted the physicians who had prescribed them, and put themselves under the care of physicians of opposite modes of practice. Most of them died. Two of them had been my patients, one of whom had recovered of a third attack of the fever under my care. AN ACCOUNT OF THE _BILIOUS YELLOW FEVER_, AS IT APPEARED IN PHILADELPHIA, IN THE YEAR 1799. The diseases which succeeded the fever of 1798, in November and December, were highly inflammatory. A catarrh was nearly universal. Several cases of sore throat, and one of erysipelas, came under my care in the month of November. The weather in December was extremely cold. It was equally so in the beginning of January, 1799, accompanied with several falls of snow. About the middle of the month, the weather moderated so much, so as to open the navigation of the Delaware. I met with two cases of malignant colic in the latter part of this month, and one of yellow fever. The last was Swen Warner. Dr. Physick, who attended him with me, informed me that he had, nearly at the same time, attended two other persons with the same disease. The weather was very cold, and bilious pleurisies were common, during the latter part of the month of February. March was equally cold. The newspapers contained accounts of the winter having been uncommonly severe in Canada, and in several European countries. The first two weeks in April were still cold. The Delaware, which had been frozen a second time during the winter, was crossed near its origin, on the ice, on the 15th day of this month. The diseases, though fewer than in the winter, were bilious and inflammatory. During this month, I was called to a case of yellow fever, which yielded to copious bleeding, and other depleting medicines. May was colder than is usual in that month, but very healthy.
