Leblanc declared tliat the epizootic of Liennes had nothing 
in common with grease^, or any other ordinary malady. 
M. Lafosse concnrred in these views of M. Leblanc^ the more 
readily as he already entertained similar ones before he had 
had any communication with that gentleman. One can 
easily conceive how he was fortified by that great authority. 
To better distinguish the difference of the two diseases, 
M. Lafosse gives the following synoptic view, which we 
transcribe, somewhat reducing it: 
Gkease. 
Erysipelatous oedema of tlie lower 
parts of the legs, bristling of the 
hair, fetid discharge, reactive fever 
exceptional. 
Loss of hair, cracks, discharge of 
fetid pus, frequently accumulated in 
smallcystsunderthe epidermis; fever 
ceases. 
Eormation of cellulo-fibrous vege¬ 
tations in groups ((/rapes). The 
purulent secretion continues; the 
tumefaction increases. 
Often becomes chronic; not con¬ 
tagious. 
Vaccinogene Eruption. 
Debut, pimples, flattened, covered 
with bristling hairs, principally af¬ 
fecting the lower parts of the legs. 
Pustules depressed, secreting a 
sanguineous fluid, which soon be¬ 
comes purulent; the hair comes off; 
the fever disappears. 
Dessication and desquamation. 
The pustules becoming dry, the 
scales fall off, leaving the parts bare, 
and showing deep cicatrices, which 
are sometimes permanent. Always 
acute and contajiious. 
It is evident from this comparison that the malady which 
was reproduced in the cow from the horse was an eruption, 
or rather an eruptive fever. This eruption belongs to the 
class of pustular diseases like smallpox, with which it has a 
great analogy; for instance, acute fever, pimples round, flat, 
and depressed in the centre, with a tendency to suppuration; 
duration from two to three weeks. If one of these pimples 
be punctured, the fluid does not run out freely, or at once, but 
slowly, as is the case with variolous and vaccine pustules, 
which are divided in the interior into several small cells. 
The question is, where did the epizootic of Liennes come 
from ? M^e have stated that, at the same time, a variolous 
epidemic prevailed in the environs. Was this a simple coin¬ 
cidence, the same influences causing the outbreak of the two 
maladies ? or did the eruption arise, one from the other, 
by contagion? Another consideration militates against the 
identity of the two eruptions. It is Avell known that the 
principal advantage of inoculation is to lessen the number of 
the pustules, and this is what constitutes its benignity. With 
it tliere is hardly any confluent variola; frequently the pus¬ 
tules only appear at the punctures where the inoculation 
had been made, and then thev are so much like those of 
vaccination, that Jenner defied the most skilful inoculators
