(2) Round worms (iiaematodes). 



(3) Tape-like worms (cestodes). 



Both the latter are very commonly 

 fomid in the intestines both large and 

 small. 



There is also an " encysted " form of 

 parasite occasionally found in the liver, &c. 



ROUND WORMS. 



Amongst these there is the so-called 

 " pin " worms, found within -the rectum. 

 The irritation produced by these parasites 

 often causes violent kicking. 



To dislodge the parasites give an in- 

 jection of turpentine, warm water, and 

 salt. About half a teacupful of turpen- 

 tine and a couple of handfuls of salt, 

 added to three quarts of water, will 

 answer the purpose. 



The four-spined strongyle (Strongylus 

 tetracanthus) is not uncommon, especially 

 amongst colts in the fen lands. It is a 

 true blood-sucking worm, causing loss of 

 flesh, pain in the belly, diarrhoea, and 

 gradual wasting of energy. At one period 

 of its life-history it is coiled up in the 

 wall of the gut, and can be seen shining 

 through when a portion of the latter is 

 exposed to the light. 



It is not an uncommon cause of in- 

 flammation of the bowels. Other worms 

 may be present along with these. It is 

 bright red in colour, and in this way easily 

 distinguished from the other varieties. 



It sometimes causes perforation of the 

 gut wall.
