Recidives may then be observed, and that is not in contradic¬ 
tion with the general data found in similar eruptive diseases. 
The variola proper to man, to which Jenner has so happily sub¬ 
stituted that of cow, under the shape of vaccine, has quite often 
manifested itself twice on the same individual. This variola of 
second manifestation, named varioloid on account of the relative 
benignity, was nevertheless true variola. It was contagious like 
the other and capable of assuming all its seriousness when com¬ 
municated to a subject as yet free from its effects. 
It is then not surprising if gourme may recidivate, when an 
animal affected in a far back period is placed in an infected 
center or inoculated a second time. This, I repeat, is not in con¬ 
tradiction with what is known since a long time. But from that, 
to admit that it may reproduce itself four or live times in the 
same animal with the change of the seasons, etc., there is no 
consistency of relation whatever. 
Because anginse, for instance, have been observed for live or 
six years successively at the same epoch and under the same 
causes, acting on the same individual, is it to follow that these 
were always true gourme? Evidently, in these peculiar cases, a 
simple inflammatory disease was taken for this specific affection. 
We know that all accidental inflammation developed in any tissue 
predisposes it to a return of the same nutritive trouble. It is 
then very natural that some animals affected with angina at a 
given time, be affected alike much easier than others under the 
influence of an exposure to cold ; but this is not gourme. 
Therefore from what has been said above, it is proved that 
1. The serosity of the pustules of the horse-pox or gourme inoc¬ 
ulated to a horse, which never had the disease, gives rise in him 
to a generalized eruption. This was produced upon six subjects 
which I had watched since birth and whose antecedents I knew. 
2. The same inoculation performed on an animal cured of the 
disease only a short time since, remains without result. 3. Upon 
an animal, which has 1 lad the disease for a long time past, the 
inoculation gives sometimes a positive result, but never as com¬ 
plete as in the first attack. Then most generally the pustules are 
developed exclusively upon the points where the virulent liquid
