AN ACCOUNT
OF THE
BILIOUS YELLOW FEVER,
AS IT
APPEARED IN PHILADELPHIA,
IN THE YEAR 1802.
The weather during the month of January was unusually moderate and pleasant. In the latter end of it, many shrubs put forth leaves and blossomed. I saw a leaf of the honeysuckle, which was more than an inch in length, and above half an inch in breadth. There was but one fall of snow, and that a light one, during the whole month.
The winds blew chiefly from the south-west in February. There was a light fall of snow on the 6th. A shad was caught in the Delaware, near the city, on the 17th. On the 18th and 19th of the month, the weather became suddenly very cold. On the 22d there was a snow storm, and on the 28th, rain and a general thaw.
In March, the weather was wet, cold, and stormy, with the exception of a few pleasant days.
The scarlatina anginosa and the cynanche trachealis were the principal diseases that prevailed during the three months that have been mentioned.
In April, there were several frosts, which destroyed the blossoms of the peach-trees.
In May, the weather was so cool as to make fires agreeable to the last day of the month. The wind blew chiefly, during the whole of it, from the north-east.
