PARASITIC DISEASES OF THE HORSE.

email intestines, and frequently enter the stomach, but from the fact 

 that they seldom exist in very large quantities, commonly do somewhat 

 less damage than the ascarides. Nevertlieless, the writer has occasion- 

 ally seen them come away by the hat-full, after a heavy dose of vermi- 

 fuge. 



How to detect their presence. — AVhen in small numbers, their exis- 

 tence is hardly ascertainable, but when in largo numbers, their pres- 

 ence will be betrayed by a capricious 

 appetite, usually a ravenous one ; ema- 

 ciation, with dry, coarse, staring coat, 

 and a pot-belly ; a whitish-yellow 

 mould will be seen around the anus, 

 probably made by worms being crush- 

 ed while passing out, leaving their 

 contents sticking to the skin, and, 

 usually, more or less of the worms 

 will be seen in the dung. When 

 they get into the stomach, the horse 

 will turn up his upper lip, as if nau- 

 seated, and will also rub his lips 

 against the wall, manger, etc. ; he 

 will lick the wall, sometimes even 



lick the hair off himself, and will persistently rub his tail or keep switch- 

 ing it around, and otherwise manifesting the irritation that exists in the 



anus and rectum. 



Giant Sti'ongle. — Another round 

 worm occasionally observed in the horse, 

 is the giant strongle, {EustrongyJus 

 Gigas,) found, most commonly, in the 

 kidneys and bladder. But sometimes, 

 after having completely devoured a kid- 

 ney, this rapacious parasite bursts the cap- 

 sule, and falling into the abdominal cavity, 

 there tloats about among the intestines. 

 It then causes peritonitis and death. These worms are as large as a 

 man's big finger, and from one to three feet long. Their color is a 

 bright pink. 



What to do for worms. — There are numerous useful vermifuges. The 

 most convenient and effectual is the f ollowinir :
