Whereunto is added, A Letter, shewing what is the proper Preparation of Persons for Inoculation, and for having the Small Pox favourably in the natural Way; and that there are Medicines, which have proved effectual to preserve Persons from the Distemper, tho they had much of the Infection at the Time of their taking them.
