Varieties of strongyli and oxyures 

 also occur, and are sometimes mis- 

 taken for ascaris. They are, how- 

 ever, distinct species; the former is 

 tapered, and terminates in a spine, 

 whereas the latter is blunted, with a 

 head like a leather sucker. The 

 strongyli inhabit the ccecum, colon,

 entery, spermatic cord, and in fact

 shank being about a third, and the 

 thong two thirds of the length, usually 

 about two inches. Sots, which in- 

 habit the stomach, will be referred 

 to especially following this article. 



There is also a small thread-like 

 worm, called filaria, from a half inch 

 to an inch and a half long, which 

 travels all through the system. This 

 is the worm that sometimes gets into 

 the eye and grows there. The tape- 

 worm is sometimes found in the horse, 

 for which I give a specific remedy used 

 by Dr. Meyer with great success. (I give illustrations of a few

 interest or importance to the general reader. Hence those ob-
