pointed bodies, as pewter, tin, etc., have no effect whatever upus 
vots; but with regard to the other parasites, rather more success 
mav be expected from medical aid, in the form of vermifuges 
It nas been attempted to effect the removal of worms meczhan- 
iclly, by dissolving the mucus they are supposed to be imbedded 
in, for which purpose lime-water, oil, solutions of aloes, etc., have 
been injected by clyster up the rectum, and which practice is mos 
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 protec- 
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 
nody, by the mechanical irritation of their spiculi, under whick 
view tin, brass, iron, and pewter are thought remedial. The In- 
dian caustic barley and Indian pink are reputed vermifuges 
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 tenia, or tape-worm, it certainly 
Joes not appear to deserve that character.”*
