The winter of 1797 was in general healthy. During the spring, which was cold and wet, no diseases of any consequence occurred. The spring vegetables were late in coming to maturity, and there were every where in the neighbourhood of Philadelphia scanty crops of hay. In June and July there fell but little rain. Dysenteries, choleras, scarlatina, and mumps, appeared in the suburbs in the latter month. On the 8th of July I visited Mr. Frisk, and on the 25th of the same month I visited Mr. Charles Burrel in the yellow fever, in consultation with Dr. Physick. They both recovered by the use of plentiful depleting remedies. The weather from the 2d to the 9th of August was rainy. On the 1st of this month I was called to visit Mr. Nathaniel Lewis, in a malignant bilious fever. On the 3d I visited Mr. Elisha Hall, with the same disease. He had been ill several days before I saw him. Both these gentlemen died on the 6th of the month. They were both very yellow after death. Mr. Hall had a black vomiting on the day he died.
