found in the large intestines. Other varieties are sometimes 

 found in the stomach and bowels, but it is not necessary to de- 

 scribe them. 



The long round-worm is from six to ten inches long, and re- 

 sembles the common earth-worm, or the same worm found in 

 the human. It inhabits the small intestines. Very large 

 numbers of them may exist in the horse's bowels, and, by their 

 drain on the food of the horse, and the obstruction they cause 

 to the natural action of the intestines, cause him to lose con- 

 dition, and though he may eat quite enough, not be benefited 

 by it. 



The needle-ivorms occupy the large bowels, sometimes in in- 

 credible numbers. They are darker-colored than the long

 inches in length. They are slim and sharp-pointed. Great 

 numbers of them often descend into the rectum^ or last gut, 

 and become very troublesome to the horse.

 could only be certainly known by parts of it being found in 

 the dung. 



Symptoms. — Worms may exist in the horse's bowels in con- 

 siderable quantity, without causing disturbance of his health. 

 The symptoms of worms are not always very satisfactory. 

 When they are troubling him much, the coat will become un- 

 thrifty, the hide tight, and belly tucked up, and the appetite 

 greedy. Cough may sometimes be caused by worms. 



But these symptoms may indicate other diseases, and, of 

 course, a careful examination for any other disease that gives 

 rise to the same symptoms should be made; and, if none can 

 be found, worms may be suspected, and remedies for their re- 

 moval given. 



But a very reliable symptom of worms is a rough, scaly ap- 

 pearance about the fundament, which may be seen by raising 

 the horse's tail. A still more reliable one is the discharge 

 of a whitish, yellow mucus, which dries up, leaving yellowish
