760 TRANSLATIOxNS FROM CONTINENTAL JOURNALS, 
on the teats with the matter; the results of which were, 
however, negative. The matter was taken from the heel, 
where there were evident traces of pustules. The pustulous 
eruption, which extended the whole length of the leg, had 
been preceded by febrile reaction. The mare belonged to 
the administration of the funeral conveyance of Paris. I did 
not see her until the malady had made some progress, and 
there existed then only some scabs in the heel, which were of 
a lenticular shape. A little moisture existed on their external 
surface. Other scabs of the same shape were also on the leg, 
but they were dry and covered the depilated surfaces of the 
skin. M. Depaul and M. Bouley have seen this mare. The 
small quantity of matter that could be collected, and the 
scabs duly diluted, were inoculated by j\I. Bouley into a cow, 
and by M. Depaul some children were also inoculated by the 
same matter, but without anv affirmative results. Mv son, 
who attended this mare, only saw her the evening before my 
visit, consequently he recognised easily the malady from the 
description I had given him of the pustulous eruptive malady 
of Toulouse. The two horses in question soon recovered, the 
same as was the case with those at Toulouse. I do not 
produce these two cases to annihilate the one at Toulouse. 
The inoculations, on the other hand, were not made under 
the same conditions. M. Lafosse inoculated eight days after 
the invasion, which was at a less advanced period of the 
malady, and directly and immediately from the horse to the 
cow; while the matter collected from the last two horses had 
been first collected in a bottle and inoculated in the cow, and 
that only after a certain time. The eruptive pustulous 
malady of Toulouse does not appear to be of very rare 
occurrence; if it has not been hitherto described, it is pro¬ 
bably on account of its little gravity; if it really were the 
variola of the horse, it would differ in this particular from 
the sheep-pox, and the smallpox in man, and would in this 
respect have a greater analogy with the vaccine, and would 
only possess an interest, viz., if it really had the virtue which 
M. Lafosse has thought he discovered in it. Admitting with 
M. Lafosse that the liquid secreted in the course of this 
malady produces the vaccine when inoculated in the teats 
of the heifers, can we say, according to the^ opinion of 
Depaul, that it is the variola of the horse transmitted to the 
cow, which then takes the name of vaccine, after being slightly 
modified in the forms, or would we say simply that a nameless 
pustulous malady of the horse, not yet classed, can provoke or 
create the vaccine, the same as has been said of the grease ? 
I would certainly incline towards the opinion of M. Depaul.
