DISEASES OF TllE BOWELS. 73 



trace of inflammatory effusion anywhere. It was chiefly in 

 reference to its bearing on the feasibility of operations in these 

 cases that the specimen was of interest. No treatment had 

 been adopted during the life of the animal, because no diag- 

 nosis had been made. The dog was in perfect health until 

 about eight days before his death, when, without any cause 

 perceptible, he began to show signs of discomfort, and refused 

 to hunt. He was never observed to be sick, nor did he pass 

 blood. He took little or no food, and his belly became much 

 retracted. For two days before his death-he was intensely 

 jaundiced. In reference to the non-occurrence of adhesions 

 between the layers of impacted intestine, it must be borne in 

 mind that experiments have established the fact that dogs 

 are but little prone to peritonitis. — Pathological Society s Trans-

Symptoms. — There are no special diagnostic symptoms of 

 intus-susception in the dog. Those of colic are generally at 

 the onset present, and are succeeded by enteritic ones. Fre- 

 quent violent straining and vomiting are also invariably pres- 

 ent. But the same may occur in strangulated hernia, and 

 other intestinal affections. 



Treatment.— P^Xzxge. diOS&oi linseed or salad oil should 

 first be administered for the purpose of mechanically facili- 

 tating the return of the invaginated portion, or inflation of 

 the bowels with air might be adopted with good results, or 

 the administration of quicksHver could be tried. The suc- 

 ceeding treatment should be' as for colic and enteritis, or both 

 combined. 



WORMS. 

 Dogs are invariably, during some portion of their lives, 

 troubled with worms, and the most common seat of these 

 pests is in the intestinal canal. It is, perhaps, hardly neces- 

 sary to observe that their presence causes their host much 

 annoyance, and is frequently productive of disease.
