WORMS. 



Worms are most commonly found in the stomach and bowels; 

 they are also sometimes met with in al- 

 most every part of the body. Investiga- 

 tion shows there are over thirty kinds of 

 worms that infest the horse. Dr. Robert 

 Jennings, about twenty years ago, at 

 that time a resident of Borden Town,

New Jersey, and now of Detroit, Michi- 

 gan, informed the writer that he had traced out thirty different 

 kinds in the horse, and among others exhibited a piece of muscle 

 that was perforated by a large number of little white worms 

 from one to two inches long. 



Mr. White, an old author, says: 



( ' I have found worms in the wind-pipe, in the mesenteric ar- 

 tery, in an abscess in the substance of the abdominal muscles, and 

 according to Lafosse, they have been found also in the pancreatic 

 and salivary ducts." 



There are but three or four 

 that are very common. First, 

 the teres lumbrici, a large worm 

 from four to ten inches long, 

 that lives in the intestines. It 

 looks like the common earth- 

 worm, yellowish white and ta- 

 pered at both ends. Second, the 

 ascaris or ascarides, commonly 

 called needle or thread- worm, of 

 a dirty- white color, Usually from FlG - 793 - The appearance of a horse 

 one to two inches long. They that is troubled with worms - 



are sometimes found in thousands. They have been observed chiefly 

 inhabiting the mucous coat of the ccecum, on the surface of which, 

 it is supposed, they are developed in little cells, which, when ma- 

 tured, burst, producing considerable irritation, and often serious 

 inflammation of the parts. They are also sometimes found to in- 

 fest the rectum in large numbers, and to relieve the irritation they 

 produce, the horse rubbing his tail.
