22G The Management and Treatment of the Horse, 



parasites are formed male and female, and as nature 

 formed nothing in vain, they must propagate in the 

 ordinary manner of reproduction. Very much has 

 been written about the parasite kingdom in relation to 

 the animal economy of late years. I do not intend to 

 enter fully into their organization, but shall be content 

 to turn out the bad tenant, and be glad when I have 

 done so. The general symptoms of being troubled with 

 worms are loss of appetite, griping pains and rough 

 coat, and tucked-up belly are symptoms of worms of 

 the larger species, lumbricus teres, or long white round 

 worm, very much resembling the long earthworm, and 

 varying in length from five to ten inches in length. 

 Itching of the rectum, evinced by quick twitching of 

 the tail, and a small quantity of mucous, which hardens 

 and has the appearance of white powder, at the anus ; 

 this is indicative of the presence of ascarides, small 

 needle-formed worms, which lodge in the larger 

 intestines, and frequently find their way in great 

 numbers into the ca3cum. A third sj)ecies, although of 

 much rarer occurrence, inhabits various parts of the 

 intestinal canal from the stomach downward; this is 

 the tapeworm, which is known from its broad, fiat, tape- 

 like appearance, and consisting of many joints. This 

 species is the most formidable and the most difficult to 

 remove. In No. 3 of the Fifth Series of Science Lectures 

 for the People, the following description of the tape- 

 worm is given : — " There is one group of worms — namely, 

 the cestoidea or tapeworm. Here we have a truly 

 singular series of creatures. Most people have heard of 

 such worms, but comparatively few have seen any.
