bowels, soon complicated by those of enteritis and finally of 

 septic infection. 



The animal looks at his flank, paws, kicks with his hind feet, 

 lies down, rolls, sits on his haunches, waves the head from side 

 to side, and sometimes eructates or even vomits. Straining may 

 be violent, with the passage of a few mucus-covered balls only, 

 and rumbling may continue for a time if the small intestines 

 only are involved. 



The partial subsidence of the acute pains, the presence of 

 tremors, dullness and stupor, the coldness of the ears and limbs, 

 the small, weak or imperceptible pulsations, the cold sweats, 

 dilated pupils, and loss of intelligence in the expression of the 

 eye and countenance may indicate gangrene, and bespeak an 

 early death which may take place in seven hours. 



The subsidence of the acute symptoms with improvement in 

 the general appearance and partial recovery of appetite may 

 indicate a spontaneous reduction of the invagination, an issue 

 which may happily arrive in any case in the early stages, but 

 especially in those implicating the caecum and colon. 



An absolutely certain diagnosis is rarely possible, unless the 

 lesion is a protrusion of the rectum, or unless as the disease ad- 

 vances the invaginated part is sloughed off and passed per anum: 



Treatment. The failure to make a certain diagnosis usually 

 stands in the way of intelligent treatment. Oleaginous laxatives 

 and mucilaginous gruels are advised to keep the contents liquid, 

 and favor their passage through the narrowed lumen of the 

 invaginated bowel. In cases implicating the floating colon and 

 rectum abundant watery or mucilaginous injections may assist 

 in restoring a bowel which has not been too long displaced. In 

 case of eversion of the rectum, the hand should be inserted into 

 the protruding gut and carried on till it passes through the 

 sphincter ani. Then, by pushing it onward, the arm carries in a 

 portion of the invaginated gut and usually of the outer portion 

 next to the anus as well, and this should be assisted by the other 

 freehand, and even if necessary by those of an assistant, and 

 whatever is passed through the sphincter should be carefully 

 retained, while the arm is withdrawn for a second movement of 

 the same kind, and this should be repeated until the whole pro- 

 truding mass has been replaced.
