FROM ANIMALS TO THE HUMAN BEING. 293 
?2th, however, hot and painful swellings appeared on the three 
animals at the place of inoculation. These tumours rapidly 
enlarged. Some of them reached the superior part of the neck, 
and others extended down to the chest, leaving between them a 
well-marked space, and which gave them the form of a knotted 
cord. Those which formed under the jaws extended up the 
cheeks to the very eyes, following the course of the glosso-facial 
vein ; they also penetrated into the nasal cavities, where they 
produced ulcers, rising above the surface, and with elevated edges, 
and essentially differing from the chancres of glanders. Twenty 
or twenty-five days after the inoculation most of these tumours 
or buttons had ulcerated, and I could perceive no difference 
between them and those of spontaneous farcy, either in their 
symptoms or progress. The glanders did not appear in the 
slightest degree modified by this new malady, but each followed 
its ordinary course. Neither of these animals was able to resist 
the united influence of these two diseases ; they rapidly wasted 
away, and were destroyed on the 1st of the ensuing December. 
It is true that there are contradictory experiments; but will 
negative facts destroy the evidence of positive ones? I think 
not. 
If, however, farcy is contagious among animals of the same 
species, is it so with regard to man ? Some facts, although few in 
number, shew the possibility of the transmission. M. Vogelihas 
related some in the Journal de Medecine Veterinaire, which are 
worthy of the fullest credit. I witnessed some of them, and particu¬ 
larly the sad fate of the student Couderq ; and I can affirm that the 
account which he has given is true to a letter. He has added nothing, 
he has embellished nothing. I was present at the last moments 
of this unfortunate young man, taken so early from his friends and 
from that science of which he promised to be one of the proudest 
ornaments. I saw all the hideous symptoms of the disease which 
tore him from us ; and although there were some symptoms 
which are rarely seen in the horse, I was struck with the resem¬ 
blance between the malady under which he laboured and farcy 
in the quadruped,—an analogy sufficient to force on me the con¬ 
viction that poor Couderq died in consequence of inoculation 
with the matter of farcy*. 
* The interesting and romantic account of the illness of this promising 
young man will be found in the 8th volume of the Veterinarian, p. 214. 
I hardly dare trust myself to speak of the impression which it made on my 
mind. It did M. Vogeli immortal credit, and I hope to live to tell him so. 
His were the feelings which ought to bind us together in the promotion of 
our common art.—Y. 
One of my fellow-students at Lyons, M. Givors, of Pont-du-Veyle, also 
wounded himself in opening an ass that had died of farcv. A little time
