Note 60 — THE NEW METHOD OF INOCULATING FOR THE SMALL-POX. DELIVERED IN A LECTURE IN THE UNIVERSITY OF PENNSYLVANIA, ON THE 20TH OF FEBRUARY, 1781.

Since the publication of the first edition of this lecture, I have heard of two cases, in one of which the fever did not come on till the twentieth, and in the other till the twenty-first day after the infection was communicated to the body. In some of these tedious cases, I have seen an inflammation and suppuration on the punctured part of the arm on the eighth day without any fever. Perhaps in these cases the inflammation and suppuration are only cuticular, and that the small-pox is taken from the matter which is formed by them.
