and in their passage through the intestines, they may attach themselves 

 to the lining membrane, and set up irritation, and inflammation of 

 the bowels, which might kill the horse. When present in large 

 numbers, and attached to the inner coat of the stomach, they, however, 

 cause the horse to lose flesh greatly, during the Winter and Spring 

 months. The best method for their removal is to give the anmial 

 some new grass, when the bots, if they are fully developed, seem 

 to realise by their natural instinct, that it is time for their next 

 transformation — that is, into chrysalides — to take place, and begin to 

 pass out. (For symptoms and treatment, see par. 254). The best 

 preventive to be adopted is to run a horse-singeing lamp over the legs 

 and shoulders of the horse, in harvest time, as soon as the little 

 tenacious yellow spots are seen. 



2CO. Worms. — Parasites found infesting the various organs and 

 parts of the bodies of domestic animals may be said to be legion. For 

 a full description of the diff'erent kinds, their names, habits, size, form, &c., 

 Dr. Fleming's translation of Neumann's Parasites and Parasitic Diseases 

 of Domesticated Animals can be consulted with interest. Some of the 

 most common worms found in the intestines of the horse are the 

 Nematoda, or round worms. The common parasites are — ist. The 

 Ascaris Mcgalocephala (Ascaris Lnmbricoidcs), a large round white worm 

 varying from seven to sixteen inches long, found in the stomach and 

 small intestine. It is also common to the ass and mule. 2nd, Oxynris 

 Corvula, a small curved worm, from one and a half to two inches long, 

 thick and curved at the front with a fine pointed tail, found in the large 

 intestine, and generally known as the maw-ivorm. 3rd, The Strongylus 

 Armatus, or armed strongyle, a straight worm, in length from one to two 

 inches, and although mostly found coiled up in the walls of the large 

 intestine — Ccrcum and Colon, — and in the intestinal canal, it is also 

 found in the blood-vessels, scrotum, &c., and is one of the most 

 numerous of the parasites found in the horse. 4th, Strongylus 

 Tetracanthiis, a spindle-shaped worm, varying in size up to one and a 

 half inches in length, and found embedded in the mucous membrane of 

 the intestinal canal.
