very much resembling in form the common earth-worm, 

 which is met with from five to ten inches in length ; and 

 itching of the rectum, evinced by a quick twitching of the 

 tail and a small quantity of mucus, which hardens and 

 assumes the appearance of a white powder at the anus, 

 is indicative of ascarides — small, needle-formed worms, 

 fvhich lodge in the large intestines, and frequently find 

 their way in great numbers to the caecum. A third 

 species sometimes, although of much rarer occurrence, 

 inhabits various parts of the intestinal-canal from the 

 stomach downwards. This is the tape- worm, which is 

 known from its broad, flat, tape-like appearance, and con- 

 sisting of many articulated joints. This species is the most 

 formidable and the most difficult to be removed.

 out are noticed, the groom should carefully watch whether 

 worms are voided, to ascertain their existence. Still, how- 

 ever, they may be lodged in the intestines without being 

 evacuated ; and when there is a well-grounded suspicion 

 that they inhabit the body, a dose of some vermifuge should 

 be given. This may consist of eight grains of calomel, 

 made into a ball, with oatmeal and treacle. 



For the expulsion of the round-worm, the following 

 anthelminthick should be administered : — 



Calomel ... 2 drachms, 

 Rhubarb . . • 1 i drachm, 

 Soccotrine aloes . . 2 drachms.
