THE DIGESTIVE ORGANS 167 



loops. Occasionally, through the presence of worms or action of a 

 spasm, a part of the small intestine becomes telescoped — that is, drawn 

 inside the neighbouring part. I have a specimen invaginated to the 

 extent of 23 inches (Plate XXL, A). Here again the pain, though 

 acute, is not nearly so severe as in loops. Tumours in the mesentery 

 are sometimes formed having a long neck, which gets twisted round 

 a part of the small intestine, thus producing strangulation. (See 

 Fig. 8, p. 163.) The animal from which the photo of the section 

 of the small intestine was taken, was ill, and suffered more or less 

 from colicky pains from 7 a.m. on Saturday morning until 10.30 a.m. 

 on the following Monday, when it died. It will be noticed that there 

 is a distinct half-hitch knot in the neck of the tumour. As already 

 stated, all these lesions are accompanied with more or less severe 

 colicky pains, and as a rule terminate fatally. 



259. Treatment for enteritis and lesions in the intestines is the 

 same as recommended for gastritis (par. 249), while hypodermic 

 injections of morphia and atropine are most to be depended on. 

 For a number of years I have noticed in lesions of the intestines 

 that about an hour before death the animal commences to walk 

 round and round incessantly until it drops and dies, which symptoms 

 I have not seen in inflammation of the stomach or bowels, although 

 large quantities of opiates have been given. 



260. Large Intestine. — I have frequently met with cases of 

 congestive inflammation of the lining membrane of the large colon in 

 which the walls of the intestine become intensely thick and jelly-like. 

 These cases, in my opinion, much resemble weed (lymphangitis) 

 in the fore or hind legs, and may be induced by giving a horse 

 affected with weed a large dose of aloes, which, acting too strongly 

 on the alimentary canal, causes the disease to shift from the leg to 

 the bowels. I make it a rule in very acute cases of weed to use aloes 

 very sparingly, and then only in solution and combined with linseed oil. 

 The large intestine may, however, be attacked with this inflammatory 

 action primarily, and without weed being present ; active treatment 

 must then be adopted — sedative medicine, such as opium, hypodermic 

 injection of morphia, also a hypodermic dose of arecoline hydro- 

 bromide, and hot blankets round the body (par. 249).
