from a tape-worm infesting dogs — the ova of 

 which are passed out in the ejecta, and believed to 

 be taken in by sheep during grazing. 



Hares and rabbits have also a larval form of 

 tape-worm, and when dogs consume the viscera 

 of these animals, tape-worm may result. All tape- 

 worm are composed of numerous segments, and 

 each segment is endowed with full repro- 

 ductive powers. These are known as maw- 

 worms. Unless the head of the tape-worm is 

 expelled, the animal will still be infested with the 

 parasites. There is a large round worm exceed- 

 ingly common in the horse, and there may be 

 a gallon of these parasites in the small bowel. 

 It is sometimes nearly 2 feet long, and pointed at 

 each end. 



If numerous the worms may block up the canal, 

 and cause death. They are a frequent cause of 

 colic. Numerous species of round worms exist 

 in the horse, and there is one that often pro- 

 duces diarrhoea in colts. This is the four-spined 

 strongyle. In the ox and also in sheep there is a 

 tape-worm known as Taenia expansa, and this 

 occasionally measures ioo feet. 



Diarrhoea in sheep, lambs and calves may be 

 caused by worms ; so may Bronchitis (see Husk, 

 Gapes, etc.). 



Several species of tape-worms are common in

 known as " Ascaris Marginata," which is a frequent
