large as the other, and when they are very numerous, 
the Inflammation and fwelling of the Face comes on 
at the ufual Time, and is followed by the fwelling of 
the Hands and Feet, and only once I oblerved a Sali- 
vation, tho’ the Puftules were diftindt. In the Natu- 
ral Small Pox, when the Puftules are very few, we 
fometimes oblerve, they do not rife to fo great a Bulk, 
neither do they ripen fb fully, nor continue fo long 
as ufiial ; and it is the fame in the way of Inoculation. 
In ihort, as this Diftemper is raifed by an Ingraftment 
from the Small Pox, as it has the very lame Appear- 
ance, and as it is capable of producing the fame by In- 
fedtion, there feems to be no room to doubt of its 
being the true and genuine Small Pox. And if that 
be allowed, it will follow from thence, as a Corolla- 
ry, that Thofe^ who have been inoculated^ are in no 
more danger of receiving the Tliftemfer again, than 
Thofe who have had it in the ordinary Way. And 
this is alfb thus far confirmed by Experience. We are 
very ready to own, that the Operation may fometimes 
fail : thofe Gentlemen, who firft communicated to the 
Royal Society fbme Account of this Pradfice from 
Turkey, did both of them intimate lb much ; tho' I be- 
lieve that will but rarely happen. In one * In- 
ftance here, I obferved no Eruption at all, nei- 
ther did the Wounds inflame and fxvell any more 
than would have follow’d from a common Incifion, 
which made me conclude, that what was apply’d had 
not taken Effedt, and indeed the Reafbn of it was very 
well known to me. In three others, tho’ the Wounds 
did inflame, and fwell, and difcharge confiderably, yet 
the Eruptions were fb imperfedt, as to leave me a little
