No wonder, my Lord, that fuch pofitive aflertions 
Ihould dagger, and cau'fe the practice of inoculation 
not to be received, till the nature of the diieafe be 
abfolutely determined, and faCts prove the contrary 
of what has been averted. 
In a matter of.fo great importance to every nation, 
it were to be wiihed, that the Marquis :de Courtivron 
had produced atteded obfervations of thefe fecond 
and third infections: for tho’ a nobleman of his rank, 
character, and great abilities, would not willingly 
impofe upon the world 3 yet it may happen, that he 
may have received wrong informations. 
As to the nature, rife, progrefs, and fatality, of 
this diftemper at Iffurtille, it appears to be the fame 
difeafe as raged in thefe kingdoms. All the fym- 
ptoms agree, as defcribed by Rammazzini, Lancifi, 
the Marquis, and in my Eday. A didempered bead; 
gave rife to the three infections. The illnefs was 
every-where the fame in Italy, France, and Britain ; 
and either terminated fatally on the fourth or fifth 
day, when a lcouring prevented the falutary eruptions, 
or in Lome cafes by abortion 3 and on the feventh or 
ninth favourably , when the puftules had regularly 
taken their courfe. Tho’ the Marquis did not ob- 
ferve, that any particular medicines were of ufe, he 
lays, that in general acids were beneficial, efpeciallv 
poor thin wines fomewhat four 3 and that the di- 
itempered beads were all fond of thefe acids (4.). 
The fatality was likewife the fame, as will appear 
from the Marquis’s tables. Of 192 head of cattle, 
.176 died. Tire mortality was chiefly among the fat
