112 THE DISEASES OF THE HOUSE. 



used by fishermen. It is from two to four iuehes long, 

 and has two distinct parts — body and tail. The tail is 

 thread-like, and constitutes more than half the worm's 

 length. When first voided, they appear black, the tail 

 and sometimes the head being transparent. When taken 

 from the dung, they vomit up their black contents and die. 



4. The ' Taenia ' (tape-worm) is white, flat, thin, broad, 

 and jointed at regular intervals. It is said to sometimes 

 measure twenty feet in length. The head, which is tuber- 

 culous and attached to the smaller end of the body, is 

 said to be directed toward and sometimes within the 

 stomach. They are rare. 



The worms are rarely numerous enough to cause death, 

 but when present in large numbers they cause more or 

 less harm. They die shortly after the horse dies. Pov- 

 erty of body, insufficient nutrition, stagnant water, and 

 miasms are said to be conducive of them. They are pe- 

 culiar to young horses. 



Symptoms. — Colicky pains; attemj:>ts to dung, but 

 little joasses except glairy mucus ; oscillatory motion of the 

 tail; rubbing root of tail, owing to itching about anus; 

 white or yellow powder about anus ; depraved and fastid- 

 ious appetite ; fond of salt ; rubbing upper lip ; coat dry 

 and rough, remaining in patches long after shedding time ; 

 hide-bound ; lean and unable to thrive ; feverish ; pulse 

 small and quick ; mouth unusually dry and warm. But 

 the best sign is the worm itself. 



Remedy. — Aloes, oil turpentine, bitters. Ferric chlo- 

 ride, copper sulphate. Aconite tincture, salt in manger. 



Oil turpentine and male shield fern for tape-worm.
