AND HIS DISEASES. 77 



We have frequently found them so thickly studded on to the 

 j)ylorus and duodenum, (first bowel,) as to give rise to con- 

 siderable disturbance, by mechanically interfering with 

 -digestion and the proper contraction of the pylorus. It is 

 very rarely, indeed, that they " eat through the coats of the 

 stomach," though we have seen cases of ulceration which 

 have been set down as the work of the bot, because they 

 happened to be found in the stomach after death. 



Symptoms. — It is very seldom that any symptoms are pre- 

 sented of their existence in the stomach, unless accompanied 

 by some functional or organic disease, existing independent of 

 the parasites. Sometimes, however, when occurring in dense 

 •clusters around the pylorus, or in the first bowel, they inter- 

 fere (mechanically) with digestion, and keep the animal weak 

 and emaciated, and subject to slight attacks of colic, capri^ 

 cious appetite, and irregular bowels. 



Treatment. — The popular remedy in Canada is sweet milk 

 and molasses, which, however, is more safe than certain. 

 We are of the opinion of Mr Youatt, who says, " they cannot 

 be removed by medicine ; " and Professor Dick, who remarks 

 that, " when arrived at maturity, they cease to retain their 

 hold of the stomach, (before this all efforts to force them are 

 vain,) commingle with its contents, pass into the intestinal 

 canal, and to the horror of stablemen, are ejected in multi- 

 tudes from the anus." Various mixtures are prescribed for 

 their removal, such as 



Aloes and assafoetida, of each, ... 3 drachm^, 



rubbed down in hot water, and when cool add an ounce each 

 of turpentine and ether ; to be given every second day for 

 a week, leaving out the aloes, if the bowels become too open. 

 To relieve the pain or uneasiness, any of the usual colic 

 mixtures will give relief. See Colic, page 79.
