SOCIETY MEETINGS. 
Mr. Loblein, a student of the American Veterinary College, 
related a case of a mare whose teeth he had been called to rasp. 
After the operation, and upon being fed a quart of oats, the ani¬ 
mal began retching, and soon vomited freely. The owner stated 
that she invariable did so after eating oats, and Mr. Loblein 
proved the truth of the assertion by inquiries among those who 
were acquainted with the animal. Hay and other food she re¬ 
tained, and he could discover no cause for this peculiar vomition. 
Dr. Critcherson asked why vomition should, as a rule, only 
follow flatulent colic, not accompanying other intestinal disorders. 
Dr. Robertson explained it by the expansion of the stomach 
and the folds of the mucous membrane at the cardiac extremity 
of the oesophagus, thereby dilating that orifice. 
Dr. MacLean claimed that it is no easy matter to diagnose 
flatulence of the stomach; that there was no symptom to guide 
one, to which Dr. Coates responded, that in such cases one will 
notice enlargement along the inferior wall of the abdomen, with¬ 
out any bulging of the flank, but later perhaps the gas would ex¬ 
tend to the larger intestines and dilate the flank. If the gas was 
in the colon, which lies along the inferior abdominal cavity, it 
would as well be manifested in the flank. 
Dr. L. MacLean asserted that a partial rupture, a laceration 
of the mucous membrane of the stomach, was the usual cause of 
vomition, and that when the rupture was complete vomition 
would not occur. 
Dr. Liautard said he could not understand why the mucous 
membrane should give way first in distension of the stomach. 
He should think that the muscular coat would give way first, and, 
consequently, complete fracture occur if any, and then the con¬ 
tractions of the stomach, while throwing a quantity of the con¬ 
tents into the thoracic cavity, would also throw considerable into 
the oesophagus, and out. In the cases he had held post mortems 
on he found the mucus membranes less extensively ruptured than 
the muscular coat. 
After closing the discussion, the essayist received a vote of 
thanks, and the society went into executive session. 
The next meeting will be held at the American Veterinary
