colon and caecum is more often perforated than the small in¬ 
testines, but in the dog the injury is about as common to one as 
the other. The colon and caecum of herbivora is generally 
distended by aliment and gas, which gives it a more fixed posi¬ 
tion than in carnivora, while the small intestines are more 
empty, more motile and more difficult to perforate than either 
the colon or caecum. Perforation of the stomach of the horse 
is more dangerous than in the ox or dog. Ruminants tolerate 
abdominal wounds much better,than solipeds. Dogs yield to 
treatment of abdominal wounds much better than other domes- 
eliotomy is a simple operation ; exploration of 
the abdominal cavity comparatively easy, and the surgical 
treatment of these injuries are generally successful in carnivor¬ 
ous animals, if the operative procedure is correct in every de¬ 
tail. When multiple perforations exist all must be sutured be¬ 
fore the cavity is closed. The perforations may be detected by 
inflating the bowels with filtered air. This method of detect-
