tenia may be known from the round worm (which 
produces colic and rending pain ;) by a pain in the 
belly with a turning motion and weight in the side, 
as if produced by some living thing; occasional 
_ pricking or biting sensation in the stomach; the bel- 
S snaliieg at intervals and suddenly subsiding; vo- 
vacious appetite, unattended by a corresponding — 
well fed appearance, but by emaciation and feeble-_ 
ness of the limbs; a feeling of constriction in the — 
nose, vertigo, vomiting, and “ an uneasy feeling 
on hearing music, particularly that of the organ.” 
From the preceding train of symptoms, it will” 
readily be seen that the remedies supposed fit to_ 
counteract the constitutional disturbance of these 
parasites, must be various; most of them act so man- 
ifestly by their drastic cathartic property, or purg. 
ing effect, as castor oil, that there seems little pro- 
priety in calling such, anthelmentics. Some are 
posed to act mechanically, as tin, cowhage, c 
water, which produces asphyxia in the animal 
when applied toit alive out of the body ; the fixed 
and volatile oils: castor oil and turpentine, are also 
supposed thus to act—erroneous. ; 
The tenia seldom resists turpentine. Bitters 
affect chiefly the round worm; while alkaline and 
irritating enemata most readily dislodge ascaride® 
' As I have discarded the classification of medica- 
ments altogether, in these lectures, it is scarcel¥ 
necessary to observe any thing relative to the ar 
ticles ranged improperly under the class noW 
noticed, by writers and teachers who adopt classi- 
fication. at own part, I somewhat doubt 
‘ific anthelmintic property as pertaining t 
cngle worm-remedy. It would not be difficult to 
shew, that they rather act by other properties 
in their effect of destroying worms. Thereare : 
cathartics, and few bitters, and few astringent ton*
