M. Tleynault ,—One of the members of great authority in 
this assembly, M. Depaul, who has made the question of 
vaccine his study, has given an opinion during this discus¬ 
sion which, with all deference to him, I believe is not well 
founded. M. Depaul, in his dissertation, has sought to 
establish—1st. That the malady called grease in the horse 
does not communicate the vaccine disease either to man or 
the cow. 2nd. That this communication is not established 
by clinical facts or by direct experiments from inoculation. 
3rd. That the horse is affected by a form of variola trans¬ 
missible to man and animals. 4th. That variola and vaccine 
are two identical maladies, vaccine being nothing more than 
variola inoculated into other animals. Such are, if I do 
not mistake, the views that M. Depaul has maintained in 
the Academy at its last two sittings, and these I desire to 
examine seriatim, therefore I beg the Academy to grant me a 
few moments' indulgence. Everybody knows that Mr. 
Jenner never prevaricated on the origin of the vaccine; he 
assigned it to a malady of the horse called grease, which he 
also designates as sore heels, and which his translator has ren¬ 
dered by the v^ovd^ javart. This opinion of Jenner, we know, 
has been much contested. For a long time it was not even 
received, except with doubt and incredulity. However, Jenner 
persisted in his first opinion in relation to the origin of the 
cowpox, and it is to grease, or sore heels, that he ascribes 
the principal source of vaccine. The reading of his Opuscule 
and correspondence, as hasbeen shown by M.H. Bouley, leaves 
no doubt on the mind in this respect. Jenner candidly 
acknowledges that he had made no direct inoculations with 
the matter of grease, but he adds that his numerous observa¬ 
tions have demonstrated this to be the source in a most 
evident and satisfactory manner. What Jenner has not 
done, viz., directly transmitted the matter of grease to
