pointed bodies, as pewter, tin, etc., have no effect whatever upou 

 'uots ; but with regard to the other parasites, rather more succeai 

 mav be expected from medical aid, in the form of vermifuges 

 It nas been attemjited to effect the removal of worms meolum- 

 ic^ily, by dissolving the mucus they are supposed to be imbedded 

 m, for which purpose lime-water, oil, solutions of aloes, etc., have 

 been injected by clyster up the rectum, and which practice is most 

 to be depended on for the ejection of ascarides when in the rectum. 

 This practice of washing away the mucus of the intestine, and 

 thus to deprive the intestine of the secretion given for its piotee- 

 tion, is not to be recommended, though oil, for this end, would be 

 harmless. Strong purges are given with the same intent, which 

 may remove them also from the whole alimentary track. Reme- 

 dies have likewise been exhibited to destroy them within the 

 Dody, by the mechanical irritation of their spiculi, under w])ich 

 view tin, brass, iron, and pewter are thought remedial. The In- 

 dian caustic barley and Indian pink are reputed vermifugca 

 against the teres and ascaris. The oil of turpentine has also been 

 strongly recommended as an excellent general vermifuge; but, 

 except for the destruction of the taenia, or tape-worm, it certainly 

 does not appear to deserve that character.***
