lince the former year, towards the end of which it ceafed 
to be epidemic. Only one has died of the natural fmall- 
pox; twelve were inoculated in Cheher, during this 
year, and all recovered. In order to determine the uti- 
lity of inoculation, it is neceflary to afcertain, by an in- 
dudlion of fa 61 :s, to what proportion of thofe who are in- 
fe( 5 led, this difeafe is fatal in the natural way. I have re- 
ceived a very authentic account of the following fa6t, 
which is perhaps the more curious and inftrudlive, as no 
medical practitioner whatever vifited any of the patients 
during the whole difeafe : at Kelfall and Aflrton, two 
fmall Chefliire villages in this part of the county, on an 
eminence of a dry abforbent fand rock, 69 perfons have 
V 
had the fmall-pox during the laft feven months;, of 
whom I 2 have died, that is, i in 5 and 3-4ths. In con- 
firmation of lafi; year’s obfervation it is proper to remark,, 
that between the ages of 1 5 and 50, more have died of 
confumptions this year, than of all other difeafes. 
The Illd table flrews, at one view, what difeafes were 
mofi: fatal in each month.
