To James Currie
Washington Dec. 25. 1801.
I inclose you a publication of Aiken’s on the Cowpox, as also some pieces from the newspapers. you will see Dr. Coxe’s experiments of the variolous after the vaccine inoculation. the matter for the latter was from me, & consequently proves that we kept the disease in it’s genuine form at Monticello, as well as that the matter I sent you was genuine. but as you deferred using it, it probably became effete, as it quickly does. the inoculation here is kept up from the same matter. health & best wishes.
