146 WORMS. 



a half in length, and not thicker than ordinary thread; 

 but these annoyances often exist in very large quan- 

 tities. They are rarely dangerous ; but they occasion 

 distress ; causing great irritation and itching about 

 the anus ; and provoking the horse to rub the hair off 

 his tail against the wall of the stable : sometimes, though 

 seldom, they have produced extensive inflammation. 

 The strongest physic, as it is usually administered, 

 will seldom expel the ascarides. They must be attacked 

 in their stronghold. 



RECIPE (No. 38). 

 Injection for Ascarides. 



Take — Powdered aloes, half an ounce ; 



Powdered gum-arabic, half an ounce: 

 Pour on them half a pint of boiling water ; shake the mixture well 

 until the aloes are dissolved or suspended, blend with the yolk of an 

 egg, and add 



Train oil, one quart. 

 Stir the ingredients well together until they are thoroughly incor- 

 porated. 



Let this be injected into the rectum every morning, 

 as long as any ascarides are voided. 



There is another slender worm which somewhat 

 resembles the ascarides, though rather longer and 

 larger : it is called the Strongylus, and, when voided, 

 its body is dark. 



In the treatment of them, as well as other kinds, 

 due regard should be paid to the general health. 

 Powerful medicines should not be given, as great 

 debility may be present; but vegetable tonics should 

 be first employed to amend the condition of the ani- 

 mal, especially as science is yet unacquainted with the 

 drug which has power to destroy the Strongylus.
