MANUAL OF MODERN FARRIERY. 
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, 
which 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. 
Remedies. —When the symptoms which we have pointed 
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 . 
Soccotrine aloes .
