AN ACCOUNT
OF THE
Bilious Remitting Yellow Fever,
AS IT
APPEARED IN PHILADELPHIA,
IN THE YEAR 1793.

Before I proceed to deliver the history of this fever, it will be proper to give a short account of the diseases which preceded it.

The state of the weather during the first seven months of the year, and during the time in which the fever prevailed in the city, as recorded by Mr. Rittenhouse, will be inserted immediately after the history of the disease.

The mumps, which made their appearance in December, 1792, continued to prevail during the month of January, 1793. Besides this disease there were many cases of catarrh in the city, brought on chiefly by the inhabitants exposing themselves for several hours on the damp ground, in viewing the aërial voyage of Mr. Blanchard, on the 9th day of the month.

The weather, which had been moderate in December and January, became cold in February. The mumps continued to prevail during this month with symptoms so inflammatory as to require, in some cases, two bleedings. Many people complained this month of pains and swellings in the jaws. A few had the scarlatina anginosa.
