ment of intestinal entozoa, but their employment 

 does not seem to be attended by any marked results. 

 Professor Mabnsten states that injections, acidulated 

 with nitric acid, were efficacious in destroying the 

 paramecia coli, observed by him in certaiQ cases of 

 cholera and diarrhoea, and in checking the henteric 

 diarrhoea which was produced by the irritation of 

 of these parasites. The other dilute mineral acids, 

 especially sulphiuic, would probably fulfil the same 

 indications. Hydrocyanic acid has been recommended 

 by Brera, and other writers, to destroy the taenia 

 when it has been partly expelled from the intestines. 



Aloes. 



Aloes, gamboge, jalap, scammony, and other 

 purgatives were formerly the medicines most fre-

 entozoa, both alone, and combiued with other reme- 

 dies. Their anthelmintic property is chiefly due to 

 their purgative effects ; but aloes appears to possess 

 a special vermifuge action. Besides its internal use, 

 it is stated to have been employed with success 

 externally, in the form of poultices made of the fresh 

 juice of the plant, and applied to the abdomen ; and 

 the instillation of tincture of aloes, combined with 

 one-half of its amount of water, between the eye-lids, 

 has been known to produce the death of filarise, 

 which were situated in the anterior chamber of the 

 eye, and which became subsequently absorbed. 



Antimonial Preparations. 



During the last century tartarised anti- 

 mony was largely employed as an anthelmintic, and 

 it has been strongly recommended for the treatment
