ORGANIC LESION OF THE PYLORUS IN THE HORSE, 
OCCASIONING ABUNDANT AND FREQUENT VOMIT¬ 
INGS AND, IN THE END, DEATH. 
By A. Sanson, V.S. at Aulay. 
The annals of French Veterinary Medicine contain few 
anatomico-pathological facts of the kind we are about to 
make mention, if indeed they contain any; at leasts we 
have met with none in the journals we have had access to, 
whose collections constitute, at the present day, almost the 
only sources of information open to us. M. Mignon, who 
must have made ample inquiry after materials for the His¬ 
torical Sketch of Vomition he read to the Central Medical 
Veterinary Society, has adduced no example. Is this, on 
account of such instances being exceedingly rare in the horse, 
or because those who have seen them have failed to record 
them ? Be this as it may, whether such cases be frequent 
or rare, the present one has appeared to us of sufficient inte¬ 
rest to take a place in our Veterinary archives, not only for 
reason of its anatomico-pathological import, but also from 
its tendency, we would hope, at least, to definitively draw 
attention to the mechanism of vomition in the horse, since, 
as M. Pigne has observed, and M. H. Bouley but a little 
while ago repeated,— (( The most brilliant conquests of phy¬ 
siology date their progress from pathological anatomy, and 
at the present day these two sciences have arrived at that 
point at which they afford each other mutual assistance; 
while all discoveries relating to physiology must, before 
they can take up their rank in science, receive the sanction 
of pathological anatomy.” 
A mare, the property of a carrier, while hardly worked and 
hardly fed, one day, while at heavy work, all at once stood 
still, stretched out her neck, and threw up through her nos¬ 
trils matters which her ow r ner believed to be excrementitious. 
A few days after he made us acquainted with what had oc¬ 
curred, and consulted about it. A phenomenon of such 
rarity, and one that had already occurred several times, as 
he informed us, failed not to excite vividly our curiosity; 
therefore we promised attentive observance. The mare, at 
this time, was at work among the ruins of a house exactly
