The intestinal worm most commonlj'^ seen is known as the Luinhncoid 

 worm. In form it is much like the common earth-worm. It is white or 

 reddish in color, and measures from 4 to 12 inches in length, though 

 some have been seen that were nearly 30 inches long. In thickness 

 they vary from the size of a rye straw to that of a lady's little finger, 

 being thickest at the middle, and tapering at both ends. They are 

 found singly or in groups or masses, and infest chiefly the small intes- 

 tines. 



Another common variety of intestinal worm is called the pin worm, 

 and is found mostly in the large intestines. These are semi transpa,reut, 

 thread like worms, measuring in length from 1 to 2 inches. 



The tape-worm, once seen, is easily recognized. It is white, flat, 

 thin, broad, and jointed. The head is found at the smaller end of the 

 worm. Tape- worms of the horse sometimes measure from 20 to 30 feet 

 in length. 



Symptoms of intestinal tcorms. — Slight colicky i^ains are noticed at 

 times, or there may only be switching of the tail, frequent passages of 

 manure, and some slight straining, itching of the anus, and rubbing of 

 the tail or rump against the stall or fences ; the horse is in poor condi- 

 tion ; does not shed his coatj is hide-bound and pot- bellied; the appe- 

 tite is depraved, licking the walls, biting the wooden work of the stalls, 

 licking parts of his body, eating earth, and being particularly fond of 

 salt; the bowels are irregular, constipation or diarrhea being noticed. 

 Some place much dependence upon the symptom of itching of the up- 

 j)er lip, as shown by the horse frequently turning it up and rubbing it 

 upon the wall or stalls. Others again declare that whenever we see the 

 adherence of a dried whitish substance about the anus worms are pres- 

 ent. The owe symptom, however, that we should always look for, and 

 certainly the only one that may not deceive us, is seeing the horse pass 

 the worms in his dung. 



Treatment. — Eemedies to destroy intestinal worms are much more ef- 

 ficient if given after a long fast, and then the worm medicine must be 

 supplemented by a physic to carry out the worms. Among the best 

 worm medicines may be mentioned santonine, turi)entine, tartar emetic, 

 infusion of tobacco, and bitter tonics. To destroy tapeworms, areca 

 nut, male-fern, and pumpkin seeds are the best. If a horse is pass- 

 ing the long round worms, for instance, the plan of treatment is to 

 give twice daily for three or four days a drench composed of turpen- 

 tine, 1 ounce, and linseed oil 2 or 3 ounces, to be followed on the fourth 

 day by a physic of Barbadoes aloes, I ounce. If the pin- worms are 

 present (the ones that infest the large bowels), injections into the rec- 

 tum of infusions of tobacco, infusions of quassia chii)s, one-half pound 

 to a gallon of water, once or twice daily for a few days, and followed by 

 a physic, are most beneficial. It should be borne in mind that intes- 

 tinal worms are mostly seen in horses that are in poor condition ; and 

 an essential part of our treatment then is to improve the appetite and
