Dry-cupping is placed with this assemblage, not 
because I have no other place to consider it as a 
therapeutic agent, but because it produces the same 
local excitement of the blood vessels in the skin 
and its vicinal parts, which is effected by other 
rubifacients, and which that name so faithfully 
identifies. I consider that Burgundy pitch, and 
similar substances usually placed here, produce a 
very different effect and in a different manner— 
pustular eruption being generally the consequence 
of their continued application, as is usual with 
this and similar substances, and by which contin- 
ued action it is deemed justly, they produce all 
their good effects as counter-stimulants. I have 
also placed tartar-emetic ointment, or this medi- 
cine applied externally in some other of the now 
common ways, among what I have called pustulat- 
ing ieritants. Where else should I place it? Surely 
not with epispastics! it does not produce any effect 
analogous to those agents. — With rubifacients? 
Clearly not. These excite heat with rednesss of — 
the skin only—this is far from being the effect of 
tartar-emetic externally applied. With liniments? — 
Impossible. It appears to me that the peculiar — 
kine-poc looking eruption which follows tartar- 
emetic externally applied, has been overlooked 
in the history of therapeutic agents, by authors of 
treatises on materia medica. They arrange it 
erroneously too, with epispastics and rubifacients. 
It is however so much employed and is really so 
important a remedy, that I have thought proper 
to refer it to some assemblage of remedies, of the 
effect of which its peculiar operation may be con- 
sidered the type.
