258 INTESTINAL PAEASITES. 



The forms of taenia observed in the horse are taenia plicata, 

 T. perfoliata, and T. mamillana. 



Symptoms. When parasites accumulate in large numbers 

 in the horse, the digestive organs become disturbed, assimi- 

 lation is imperfect ; however rich and abundant the food, the 

 animal does not thrive, and is hide-bound. This condition 

 predisposes to various disorders, and is attended with occa- 

 sional attacks of colic. 



Treatment. A brisk purge may sometimes suffice to clear 

 the parasites out of the intestine, and restore the animal to 

 health. In many instances further treatment is called for, 

 and either of the following prescriptions may be used 

 1 Iron filings . . . . 6 oz. 



Common mass, sufficient to make 12 balls, one of which 

 must be given every morning, and on the twelfth day a good 

 dose of aloes, which will cause a copious discharge of 

 worms. Or 



1% Sulphur 12 oz. 



Arsenic 1 drachm. 



Bruised coriander seeds . . 6 oz. 



Divide into twelve powders, and give one daily for twelve 

 days. This is a very sure remedy in cases in which the as- 

 caris megalocephala is abundant. 



The ox is not very much tormented with parasites, and I 

 can only repeat what I have said in my work on Dairy Stock, 

 that " the strongylus radiatus and ascaris lumbricoides are 

 amongst the most common round worms to be met with in 

 the intestine of the ox. Ascarides abound in the small in- 

 testine of weakly calves, within a very short time after birth, 

 and the system suffers very severely, as indicated by great 

 emaciation; and when the animals are killed, the flesh has a 

 peculiarly disagreeable, mawkish odour. The best remedy in 

 these cases is iron, either in the form of iron filings or pow-
