and salt, he is directed to take in the morning, while in bed, a 
dose of two or three drams of the powdered root of male fern. 
(The dose for infants is one dram.) The powder must be washed 
down with a,draught of water, and two hours after a strong 
cathartic, . composed of calomel and scammony, is to he given, 
proportioned to the strength of the patient. If this does not 
operate in due time, it is to be followed by .a:dose of purging 
salts, and if the worm be not expelled in a few hours, this process 
is to be repeated at. proper intervals. Of the success of this, or a 
similar mode of treatment, in cases of tania, there can be,no-doubt, 
as many proofs of it in this country afford sufficient testimony ;* 
but whether the fern root or the strong cathartic is the principal 
agent in the destruction of the worm, may admit of a question, | 
and the latter opinion we believe is the more generally adopted 
by physiciaus.£ It appears, however, from some experiments 
made in Germany, that the tenia has in several instances been 
expelled by the repeated exhibition of. na root, without the 
assistance of any purgative.®
