Snch another Account has bcentranfiiiitted tome from 
Haverford W in South JV^les^ by the Learned 
Dr. ‘Terrot Williams, Phyfician in that Place. The 
Sum of thefe Accounts is as follows.

From which it appears, that, upon a Medium be- 
tween thele Accounts, there died of the SmallTox al~ 
mofl 19 fer Cent, or nearly one m five, of Perfons of 
all Ages, that underwent that Diftemper. Which is 
the more to be remarked, for that out of%t Perfons, 
that had the Small Pox by Inoculation, the fame Year, 
and in the Neighbourhood of the fame Places, not one 
mifearrfid. 
Mr. Mather obferves, in his Letter mention’d above, 
that out of more than ^000 Perfons that had the Small 
*Pox at Bofion in Nevu England, within little more 
than half a Tear, near 900 died, which is more than 
one in fix ; and this Account added to thofe from 
Torkjhire, Chichejier^ and Wales, reduces the Propor- 
tion of thofe that die of the Small Pox to fomCwhat 
more than 18 fer Cent, fb that the Hazard of dying 
of that Diflemper, to thofe who are taken ill of it, is 
that of one in between five and fix, or fomething 
above two in eleven. 
The Refult therefore. Sir, of thefe Computations is, 
that, if the fame Proportions fhould ftill continue, as 
have hitherto been determin’d by ObfervatioU, we 
muft exped,
