Who happily introduc d from Turkey, into this Country, The Salutary Art Of inoculating the Small Pox. Convinc d of its Efficacy She first tried it with Success On her own Children. And then recommended the practice of it To her fellow Citizens. Thus by her Example and Advice, We have soften d the Virulence And escap d the danger of this malignant Disease 1789
