been conveyed out of the body by the torpid or 
inactive emunctories of the surface. The whole 
of Dr. Paris’ reasoning on this point, is unan- 
Swerably true, and the ‘well regulated doses of 
the compound powder of ipecacuan,” which he 
Says, ‘frequently furnish the oppressed asth- 
matic with a valuable resource,” I know from ex- 
perience do have that remediate effect. But for . 
this reason is this compound medicine, or are the 
ingredieuts of which it is composed, to be called 
expectorants? Is not this action, manifestly, by 
restoring the sympathetic concert of function, 
now dissociated, between the skin, the lungs and 
the kidnies, to their healthy routine of action? 
Do they not do this, palpably, by opening the arid 
skin? And what are medicines which do this but 
diaphorctics. Diaphoresis is the primary and 
evident effect of the medicine specified and its like: 
Hiberation of congestive serous or mucous en - 
ment of the lungs and its appendages, the alterior 
consecutive effect. " 
- Section d of the same class is predicated on the 
same principle as the preceding section, embracing 
such medicines as excite serous discharges from 
the bowels, as saline cathartics. They relieve 
the lungs on the same principle, and avowedly, — 
are not expectorants by any other effect than one 
involved in the general return they produce, of 
regular, healthy and equalized action in the gen- 
eral system. Why then cal) them so? 
We are thus led to class third comprising me- 
dicines which operate mechanically, and the first 
section a, points to those which impart vigour to 
the respiratory muscles engaged in the act of ex- 
pectoration, Itis grounded on a fact universally 
admitted, that the act of expectoration is chiefly 
voluntary. We all know this, and an effort to
