AN
ACCOUNT OF SPORADIC CASES
OF
YELLOW FEVER,
AS THEY
APPEARED IN PHILADELPHIA,
IN THE YEAR 1804.
The month of January was marked by deep snows, rain, clear and cold weather, and by the general healthiness of the city.
In February there fell a deep snow, which was followed by several very cold days. There was likewise a fall of snow in March, which was succeeded by an uncommon degree of cold. Catarrhs and bilious pleurisies were very common during both these months.
In the beginning of April, the weather was cold and rainy. There were but few signs of vegetation before the 15th of the month. Bilious pleurisies were still the principal diseases which prevailed in the city.
The month of May was wet, cool, and healthy.
In June, the winds were easterly, and the weather rainy. The crops of grass were luxuriant. It was remarked, that the milk of cows that fed upon this grass yielded less butter than usual, and that horses that fed upon it, sweated profusely with but little exercise. On the third of the month, I was called upon by Dr. Physick to visit his father, who was ill with a bilious fever. He died on the seventh, with a red eye, hiccup, and black vomiting.
