DISEASES AND THEIR TREATMENT. 



Varieties of 'strongyli and oxyures also 

 occur, and are sometimes mistaken for 

 ascarides. They are, however, distinct 

 species ; the former is tapered, and ter- 

 minates in a spine ; whereas the latter 

 is blunted, with a head like a leather 

 sucker. The strongyli inhabit the cae-r 

 cum, colon, and # duodenum ; the oxyures, 

 the mesentery, spermatic cord, and in 

 fact almost every organ in the body. 

 The common whip-worm, or long threads- 

 worm, technically called the trichoceph- 

 alus dispar, are found in the caecum. 

 They resemble a whip, the shank being 

 about a third, and the thong two thirds 

 of the length, usually about two inches. 

 Bots, which inhabit 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 

 worms, though not of all that I desired, 

 on account of the difficulty of obtaining them. They will not, how- 

 ever, be of any special interest or importance to the general reader-

Hence those obtained are put in without regard to much technical 

 explanation.) 



Symptoms of worms are debility, feebleness, sluggish move-
