was passed to other children. I had at the same time vaccinated 
another cow and several pigs with equal success. 
I may here say that this last animal is a good subject for the 
cultivation of vaccine —a long series of experiments authorizes 
me to make this statement. 
But to return to the horse, the subject of these remarks : For 
several days he ran abundantly at the nose, had a large lymph¬ 
angitis on the left side of the upper lip, with pseudo-ulceration* 
three abscesses in the sub-glossal ganglions; in fact, all the symp¬ 
toms of gourme in its most common form. 
What ailed him when I took from his nostrils the vaccinating 
liquid ? Probably, perhaps surely, pustules developing in the 
nasal cavities, or perhaps in the pharynx or larynx. 
This, it seems to me, needs no comment. It is sufficient by 
itself to prove that gourme is truly the vaccinageneous affection, 
and that in its essence it is truly horse-pox. 
Other important questions remain to be considered in relation 
to the inoculability of gourme. These are: to know how long* 
the liquid exudated on the surface of the respiratory mucous mem¬ 
brane remains virulent; if it is so after it has become purulent; and 
if the pus of the lymphangitis and of the ganglionary abscesses 
remains such for a variable length of time. The solution of all 
these problems I am not yet prepared to announce. 
M. Martin, it is true, has transmitted gourme or some¬ 
thing like it, to young horses, with the pus of diseased animals ; 
but I do not consider his facts as essentially demonstrative : for 
it is proved to-day, that inflammatory products are phlogogenous. 
Placed in contact with healthy tissues, they produce in them 
inflammatory processes. Here is then, a cause of error when 
one operates on the horse. In inoculating him, or placing on a 
portion of his mucous membrane pus from another horse, one 
cannot be assured that the result will not exceed a simple inflam¬ 
mation. 
Specific pustular eruptions alone may furnish a sure proof of 
the virulency of the liquid employed. To obtain this without 
fear of confusion, the best ground is the cow virgin of vaccine. 
It is by a series of experiments executed in this manner, that the
