eter) into the rectum by means of a bicycle pump. This would be 

 just as applicable in veterinary practice. The procedure should be 

 conducted slowly and carefully and, after the lower gut has been 

 well distended, time may accomplish a reduction of the invagination. 

 * Passage of a necrotic portion of the bowel is pathognomonic, but 

 the proposed treatment at such a time would be out of the question. 



Colic caused by new-growths of the bowel or stricture may be 

 diagnosed by rectal exploration. There is little to be done except 

 to empty the rectum by enema or manually twice daily. 



Colic due to worms is of a mild character, is apt to recur, to 

 alternate with other digestive disorders, and to attack young 

 animals. It is produced by obstruction of the bowels and irritation 

 of the intestinal mucous membrane. Round, tape, and thread 

 worms; the larva of Gastrophilus equi and hemorrhoidalis, and 

 several others, may induce colic. The discovery of worms or their 

 larvae in the feces is the only positive evidence of their presence. 

 The treatment is that recommended for worms under the heading 

 of that name. 



Colic due to torsion of the colon. This is discovered by rectal 

 examination. To relieve, puncture the bowel to allow escape of 

 gas and then roll the animal. If the colon is twisted to the right, 

 roll to the right; if to the left, roll the animal to the left. 



Conjunctivitis in All Animals. 



Conjunctivitis may be conveniently classified as Acute Catar- 

 rhal, and Purulent and Chronic; while less frequently are seen 

 Membranous, Follicular, Granular and Phlyctenular forms. 



In acute catarrhal conjunctivitis the lids are somewhat swollen 

 and there is a muco-purulent discharge. Congestion of the mucous 

 membrane of the lids and eyeball is present, the color being brick- 

 red. On the eyeball the vessels are tortuous, superficial and mov- 

 able, forming a coarse, irregular network in all directions, and not 

 confined to the corneal border. It is of special importance not to
