My Lord, 
Read May 5. f ■ A HE inclofed account of inoculation 
8 in the Eaft, I have juft received 
from my brother at Aleppo, and though nothing far- 
ther feems wanting, in this country to remove preju- 
dices againft that practice, yet 1 thought its being 
made public might be of l'ome ufe toother European 
nations, where fuch prejudices Rill prevail ; and as 
a matter of curiofity, would not be unacceptable to 
the Royal Society. I have therefore taken the liberty 
to trouble your Lordfhip with it for that purpofe„. 
Juft before my leaving Aleppo, 1 did hear that it 
was pradtifed amongft. fome of the Bedouins there, 
and went by the name of buying the fmall pox; but 
being then much engaged with other bufinefs, it quite 
efcaped my memory, and indeed my information' 
was fo flight, that I did not think it right to mention 
it in my Natural Hiftory of Aleppo.
