enormous size, weighing about forty pounds, and presented a 
laceration in the middle of the posterior face of the right cul de 
sac, about ten centimeters from the great curvature and parallel 
to it. The edges of the laceration were bloodless, clean and 
without ecchyinosis. The contents of the stomach had passed 
through the opening into the abdomen. 
The stomach being removed, a very irregular laceration of 
the diaphragm was found, beginning a little above the foramen 
of the right pillar of the muscle, somewhat to the right, and 
running down through the left pillar. It was at first horizontal 
and then extended obliquely upwards. The section of the fleshy 
part of the right pillar was complete and irregular. The edges 
presented little blood clots and ecchymostic spots. A similar 
condition was found on the fibres of the left pillar and through 
those of the phrenic center, which were also torn. Some portions 
of those, however, were also bloodless. 
The case was thus proved by the post mortem to have been 
rupture of the right and left pillars of the diaphragm, before 
death, which was increased by the formation of gases in the ab¬ 
dominal organs, which gases also produced the laceration of the 
walls of the stomach after death .—Becueil de Medecine Veter-

CONTRIBUTION TO THE STUDY OF THE TRANSMISSION OF 
TUBERCULOSIS. 
By M. H. Toussaint. 
Veterinary pathologists agree in admitting that tuberculosis 
is unknown or at least very rare in pigs. This however, is not 
due to an inaptitude in that animal to contract the disease. The 
experiments of Mr. S. Cyr, in 1874, repeated since by several 
other pathologists, show evidently the facility with which the 
tuberculous infection takes effect in pigs. While nothing is more 
common in slaughter-houses than tuberculous organs of oxen or 
cows, one will look in vain for tubercles in a pig. 
To what cause may these differences be attributed in animals
