Evans does not record this 1791 imprint, although Austin does. AAS evidently does not own it. The first American printing issued from Philadelphia in 1790; this one was followed by Philadelphia printings in 1793 and 1795, and a 1797 Vermont.
Phinehas Parkhurst [1760-1844] was born in Plainfield, Connecticut, and later moved to Lebanon where he was one of its earliest settlers. He practiced medicine in Connecticut, but demand for his services extended as far as Vermont and New Hampshire. His desire to study medicine came from his experience with a wound suffered at the hands of Indians in his childhood. In addition to medicine, Parkhurst raised and sold mules.
