nauseants? What are they?) The most stimulat- 
ing emetics in small and divided doses. Why 
then call them expectorants, seeing expectoration 
when induced by them at all, is only one of a series 
of effects—one link of a catenated chain of associ- 
ated irritative actions? 
In regard to his second section of the same 
class, which comprises medicines suited to stimiu- 
- late the pulmonary exhalents by the actual contact 
of their medicinal principle, I cannot butsay there — 
is mach gratuitous foundation. The instance of 
garlic given by him, of a substance taken into the — 
circulation, and evincing a peculiar determination 
to the lungs, is anunlucky one. Itis tree that the 
volatile and penetrating odour of this root is per- 
ceptible in the breath, and that this is also per- 
ceived as sensibly if it have been externally applied 
to the soles of the feet, as when internally taken. 
This proves the subtle and diffusible nature of its 
odoriferous principle whatever that may be: and 
further proves the readiness with which the 
circulating fluids of the body convey through their 
devious course, and by their mysterious operation 
—volatile odours ; but to my satisfaction itdoes not 
prove, that the medicinal property has a peculiar 
predilection for the lungs. [f the alliaceous odour 
of the breath evidences this predilection, as it is as- 
sumed, it does—if that be the criterion of its expec- 
torant effect (to use common parle) why does not this 
effect supervene to the application of garlic to the 
soles of the feet? It is a disagreeable medicine to 
most persons, intolerable to many, and in some — 
idiosyncracies, a dangerous one, inducing convul- 
sions and cerebral hebetude. Why do we not in
