The month of November, and all the winter months which followed the autumnal epidemic, were in general healthy. A catarrh affected a number of people in November. I suspected it to be the influenza which had revived from a dormant state, and which had not spent itself, when it yielded to the predominance of the yellow fever. This opinion derives some support from a curious fact related by the late Mr. Hunter of the revival of the small-pox in a patient, in whom it had been suspended for some time by the measles[60]. The few fevers which prevailed in the winter were highly inflammatory. The small-pox in the natural way was in several instances confluent; and in one or two fatal. I was prepared to expect this inflammatory diathesis in the fevers of the winter; for I had been taught by Dr. Sydenham, that the diseases which follow a great and mortal epidemic partake more or less of its general character. But the diseases of the winter had a peculiarity still more extraordinary; and that was, many of them had several of the symptoms of the yellow fever, particularly a puking of bile, dark-coloured stools, and a yellow eye. Mr. Samuel D. Alexander, a student of medicine from South-Carolina, who was seized with a pneumony about Christmas, had, with a yellow eye, a dilated pupil and a hard pulse, which beat only fifty strokes in a minute. His blood was such as I had frequently observed in the yellow fever. Dr. Griffitts informed me that he attended a patient on the 9th of January, in a pneumony, who had a universal yellowness on his skin. I met with a case of pneumony on the 20th of the same month, in which I observed the same degrees of redness in the eyes that were common in the yellow fever. My pupil, Mr. Coxe, lost blood in an inflammatory fever, on the 18th of February, which was dissolved. Mr. Innes, the brewer, had a deep yellow colour in his eyes, on the fourth day of a pneumony, on the 27th of the same month; and Mr. Magnus Miller had the same symptom of a similar disease on the 16th of March. None of these bilious and anomalous symptoms of the inflammatory fevers of the winter and spring surprised me. I had been early taught, by Dr. Sydenham, that the epidemics of autumn often insinuate some of their symptoms into the winter diseases which follow them. Dr. Cleghorn informs us, that "the pleurisies which succeeded the autumnal tertians in Minorca, were accompanied by a vomiting and purging of green or yellow bilious matters[61]."

It belongs to powerful epidemics to be followed by similar diseases after they disappear, as well as to run into others at their first appearance. In the former case it is occasioned by a peculiar state of the body, created by the epidemic constitution of the air, not having been changed by the weather which succeeded it.
