this subject has been ably treated by Professor Cooper, of 
Philadelphia, in his ingenious discourse upon the connex- 
ion of chemistry with medicine, and in which it has been 
plainly shewn- that be applications of chemical science 
throw much light upon the reprobated doctrine. As an ad- 
ditional proof to what has been there and elsewhere stated 
of active substances being found in different viscera of the 
human body, after being taken into the stomach, it may
