AN ACCOUNT
OF THE
BILIOUS YELLOW FEVER.
AS IT
APPEARED IN PHILADELPHIA,
IN 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.
In the first week of June, several cases of highly bilious fever came under my care. In one of them, all the usual symptoms of the highest grade of that fever occurred. On the 13th of the month, Dr. Physick informed me, that he had lost a patient with that disease. On the 23d of the same month, Joseph Ashmead, a young merchant, died of it. Several other cases of the disease occurred between the 20th and 29th days of the month, in different parts of the city. About this time, I was informed that the inhabitants of Keys's-alley had predicted a return of the yellow fever, from the trees before their doors emitting a smell, exactly the same which they perceived just before the breaking out of that disease in 1793.
