AN ACCOUNT
OF THE
BILIOUS YELLOW FEVER.
AS IT
APPEARED IN PHILADELPHIA,
IN 1798.

The yellow fever of the year 1797 was succeeded by scarlatina, catarrhs, and bilious pleurisies, in the months of November and December of the same year. The weather favoured the generation of the latter diseases. It became suddenly cold about the middle of November. On the 5th of December, the navigation of the Delaware was obstructed. There was a thaw on the 13th and 14th of this month, but not sufficient to open the river.
