From Benjamin Rush
Philadelphia July 29. 1799
Herewith you will receive two pamphflets, the one upon the causes of Animal life, the Other upon the Origin of the yellow fever in our city, & upon the means of preventing it. The latter has been generally read by our citizens, and has removed a small portion of their prejudices upon the Subject of our annual calamity. But time, and Another Visitation by the disease, I fear will Alone cure us of our Absurd, & destructive belief in its importation.
Adieu. Continue to number me among your friends. While Science, and the principles & events of 1776, are congenial to my heart, your name will be dear to
