The Marquis de Courtivron, in two memoirs read 
before the Royal Academy of Sciences in the year 
1748, and published by that learned body, relates 
the obfervations he, together with Monfieur Pel- 
verder de Gombeau, formerly furgeon to the regi- 
ment de la Sarre, made on the rife, progrefs, and 
fatality, of the contagious diftemper at Iffurtille, 
a town in Burgundy ; to which are added experi- 
ments they made, by application, digeftion, and 
inoculation, towards communicating the difeafe * 
and concludes from the failure of thefe attempts, 
that the diftemper can only be communicated from 
one beaft to another. Befides, notwithstanding the 
Marquis obferves ( 1 ) the regularity of the illnefs, the 
critical days, on the feventh and ninth, and particu- 
larly that all fuch as recovered had more or fewer 
puftules broke out in different parts of the body; 
yet (2) he will not allow of Rammazzini’s opinion, 
of the analogy between this diftemper and the fmall- 
pox, nor that it is an eruptive fever ; but ranks it 
as a plague. 
But the Marquis goes ftill farther. He pofitively 
fay, (3) “ That in the preceding years, in the pro- 
“ vinces of Breffe, Maconnois, andBugey, fomepri- 
tc vate perfons had Suffered by buying cattle reco- 
“ vered from the diftemper, which had, at that time, 
“ the puftules remaining on them : which cattle had 
<c the diftemper afterwards.” Nay, he adds that 
,£ even after recovering twice, a third infection has 
“ feized and killed many.”
