DISEASES AND TREATMENT OF THE HORSE 163 
22. Long, Round Worms (Lumbrici). 
Symptoms. — A horse troubled with these worms does 
not do well. He soon falls off in condition and frequently 
passes some of them in the manure. If very many are present 
they cause attacks of colic and we have known cases in which 
these worms have accumulated to such an extent as to form 
a ball in the small bowels, stopping the passage and killing 
the animal. 
Treatment. — Get rid of the worms by giving: 
Raw Linseed Oil Yi. pint 
Spirits of Turpentine 1 ounce or 4 dessertspoonfuls. 
Mix and give as a drench once a week. In addition to 
this give a teaspoonful of sulphate of iron in the feed twice 
a day. This is the best remedy known for worms. 
23. Pin Worms. 
These are short, fine worms about an inch or two long 
and only affect the rectum or back bowel. 
Symptoms. — A horse affected with pin worms usually 
feels, fairly well. He, however, falls off in condition ; his coat 
becomes dry and dusty ; he rubs his tail and there is a white 
slimy matter visible around the anus.
