INFLAMMATION OF THE INTESTINE. 283 



In cattle, the grinding of teeth, hot and dry mouth, ten- 

 dency to tympanitis, and tenderness of the abdomen, with ob- 

 stinate constipation in some cases, or very free and trouble- 

 some diarrhoea in others, constitute the leading features of the 

 disorder. 



In the pig there is great dulness, grunting, and other signs 

 of uneasiness, besides a troublesome retching, and in the 

 early stages a morbid appetite, which soon subsides. Ulcer- 

 ation of the intestines is not an unfrequent result of enteritis 

 in this animal. 



In the dog it is said that the signs of enteritis approach 

 those of the dumb or paralytic form of rabies, but there are 

 more severe symptoms of fever: hot and dry nose, sharp 

 and very frequent pulse, cold limbs, a dry skin, and arched 

 back ; tenderness over the region of the belly ; and, as in all 

 other animals, there is either obstinate costiveness or diarr- 

 hoea, according to the cause of the attack. 



Post-mortem appearances. These are unmistakeable, and 

 it is no slight redness or turgescence of the large vessels, such 

 as we find in fatal cases of simple colic, that may be regarded 

 as characteristic cadaveric lesions of enteritis. The mucous 

 coat is tumefied, of a very dark red colour, generally over a 

 large extent of surface. The redness is first observed on the 

 peritoneum, and, indeed, all the coats are involved, as indi- 

 cated by the amount of exudation in their substance. I have 

 seen, in a portion of intestine transmitted to me by a practi- 

 tioner, the thickening attain nearly half-an-inch. I have seen 

 not unfrequently a number of small ulcers in the small intes- 

 tine of the dog, and the contents of the first portion of the 

 canal especially of dark coffee colour, or tinged red, from 

 blood extravasation. 



Treatment. Any irritant that may be present in the 

 bowels must be removed by a purgative. In the horse, espe-
