INFLAMMATION OF THE INTESTINES. 135 



the attendant of both ; and I am not sure that the use of drastic 

 purgatives will not produce the intussusception as often as prevent 

 it. If it could be recognised, there would be no great danger to 

 the dog in opening the abdomen and drawing out the intestine ; 

 and in a very obstinate case of colic I should be inclined to try 

 the experiment, when all other means have failed. The dog bears 

 operations so well about the abdomen, that I should have no fear 

 of any increase of mischief from the operation. The best 

 remedies in colic that I know of are croton oil and opium, one 

 drop of the oil to two or three grains of opium every six hours. 

 Two hours after their exhibition the dog should be put into 

 warm water at 98 Fabr., and, while there, with an enema syringe, 

 should be pumped, per anum, as full of the water in which he is 

 placed as he will bear without using dangerous force. This 

 remedy is very efficacious, and will often remove the colic in slight 

 cases, without the croton oil and opium. But when the disease is 

 very severe, the two should be combined ; as soon as there is a 

 free evacuation, the danger generally disappears at once. 



IN DIARRHCEA. and DYSENTERY, which are both the results of in- 

 flammation of the mucous coat of the bowels, there is great 

 looseness of the bowels, with the passing of quantities of mucus, 

 often tinged with blood. The distinctions between the two are 

 variously given by different writers, but the most common 

 distinction is merely one of degree. Thus, diarrhoea is merely 

 a loose state of bowels owing to errors in diet or mismanagement 

 of some kind, while dysentery is accompanied with mucus or 

 blood, or both, and is often epidemic, or dependent upon some
