Notes: “In the summer of this year (1800) Mr. Ring, of London, sent Dr. John Crawford of Baltimore, some vaccine virus, which was successfully used by Dr. Crawford in Baltimore. (This was contemporaneous with its earliest use by B. Waterhouse, July 8, 1800, see Ring on Cowpox, 1801. p. 459.). The supply of Waterhouse and Crawford gave out with these experiments, and Dr. Waterhouse’s second supply arrived in the spring of 1801, at the same time with that of Dr. James Smith.”
