normal, no change in auscultation or percussion, no pain, no dis¬ 
turbance in the circulation. The animal being killed for dis¬ 
section the following lesions were discovered, explaining at last 
the cause of the meteorism, but at the same time showing what 
lesions can sometimes exist in animals and yet fail to give rise 
to any disturbance of importance. In the diaphragm, the mus¬ 
cular portion remained normal, but the phrenic part was reduced 
in size to about onlv a few centimetres in width. There was a 
j 
rupture through it, in which the oesophagus passed and which 
measured 25 cent, in height and 20 in width, and contents of 
the abdomen had passed into the thoracic cavity. Contained in 
a hernial sac, formed by the layers of the posterior medias¬ 
tinum, which were separated, there was found the entire mass of 
the omasum, the three anterior quarters of the reticulum, the 
anterior extremity of the abomasum, measuring about 10 centi¬ 
metres, and the lower portion of fhe liver. The omasum had 
retained its normal size and contained cakes of dry food between 
its lamellae ; the reticulum was small and empty, the displaced 
portion of the liver was atrophied and reduced to its fibrous 
envelop. The abomasum was normal. The mass of all these 
organs formed on front of the diaphragm an ovoid lump, re¬ 
lated in front to the heart, above to the lungs, behind to the 
lower portion of the diaphragm, and below to the sternum. It 
extended laterally fiom the posterior border of the fourth rib to 
the anterior of the seventh without, however, coming in contact 
with their internal faces. The heart was pushed forward and 
the lungs pressed toward the upper part of the thorax ; they 
were small and more or less affected with interalveolar and sub- 
pleural emphysema. All the other organs were healthv.—

Double Inguinal Hernia in a Colt—Radical Opera¬ 
tion—Recovery [Dr. A. Fontaine ].—The subject was a 
colt, aged three and a half months, which was taken one night 
with colicky pains and was found affected with hernia of both 
sides. On the left it is as big as a child’s head, on the right as 
large as the fist. On account of the large size of the hernia it is 
decided to operate at once, and to resort to the modus operand1 
for radical cure, by a process analogous to that used in human 
surgery. The only possible difficulty was the presence of the 
testicle and its gubernaculum in the protruding mass, and the 
question then was whether it would be better to remove it or re¬ 
turn it into the abdomen. It was decided to amputate it. With 
all antiseptic precautions as far as sterilization of the instru-
