It is a fingular faét, that it has, been Jong known -by 
country farmers and others, that this difeafe, which in, fe- 
yeral counties prevails at particular feafons among. the 
cows, and is often communicated to the hands of the milk- 
ers, exempts fuch as have been fo) infected from being 
infected with the fmall-pox.—It is fill more fingular,: that 
though they knew this fact, and alfo that no cow or human 
being had ever been known to die of the cow-pox, they 
neyer thought of having recourfe to a voluntary infection of 
this kind, to free themfelves and families from the poffibi- 
lity of being infected with the variolous poifon, which {oe 
often proves mortal even when given by inoculation. 
Thefe publications contain a great body of evidence, all 
tending to prove that perfons who have undergone the fpe- 
cific fever and local difeafe occafioned by the cow-pox, com- 
municated either by accident to the hands when milking 
them, or by inoculation (for this has been already tried by 
the ingenious authors), are thereby rendered unfufceptible of 
the fmall-pox ; and that matter from fuch patients may be 
employed with the like effects, no difference being obfery- 
able in the effeéts of the matter generated fucceffively in the 
firft, fecond, third, fourth or fifth human creature. 
Pits from the fmall-pox are a deformity that no one can 
-certainly guard againft even by inoculation. In the cow- 
pox no fuch confequences take place; for, though accom- 
panied with fever, the prfiules are local, and the place may 
be chofén. 
According to fome cbfervations, (but this is not quite 
eertain,) the fame perfom may repeatedly have the cow=pox: 
If fo, praGitioners may avail themfelves of this’ ‘mean ‘of
