n4 THE IMPROVED ART OF FARRIERY. 



WORMS 



Are very general among horses, but seldom do hurt, 

 except where they are found in great numbers. There 

 are several descriptions of these animals found in the 

 intestines of the horse, but the most common is the 

 hot, on which Mr. Bracy Clark has taken some pains 

 to treat and illustrate ; some assert they are perfectly 

 harmless, and do not interfere with the general health 

 of the animal : others differ in opinion ; and Gibson 

 says, " The hots that many horses are troubled with 

 are found sticking to the rectum, and are often thrust 

 out with the dung, along with a yellowish coloured 

 matter like melted sulphur. 



** They are apt to make a horse restless and uneasy, 

 and to rub his breech against a post. The season of 

 their appearing is usually in the months of May or 

 June ; after which they are seldom to be seen, or rarely 

 continue in any one horse above a fortnight or three 

 weeks. Those that take possession of the membrane- 

 ous part of the stomach are more irritating and dan- 

 gerous in causing convulsions, and are seldom disco- 

 vered by any previous signs before they bring a horse 

 into violent agony." There are beside these the lubricus 

 teres, not unlike the common earth-worm. The 

 toenia, or tape-worm, is seldom found among horses ; 

 the whip-worm likewise rare ; and the ascarides, or 

 thread-worm, which sometimes exist in large num- 

 bers, and are very hurtful. 



Symptoms. — An irregularity of appetite as well as of 

 the bowels, and sometimes a dry yellow matter is found 

 under the tail. When the teres abound, the skin ge- 

 nerally sympathises with the bowels, the coat stares
