a numerous aggregation of agents, acting by mul- 
tifarious peculiarities, and should, in my opinion, — 
be disciplined. For want of a better division I 
shall separate these vomiting agents into three 
classes, and each class into sections. The first 
two classes and section d, of the third class, em-

those agents resorted to in obdurate chronic dis- 
eases, and never in acute disorders.

pendently of nauseous taste or fla- 
vour, but by the stimulus of over-dis- 
tension from quantity and unusual 
temperature. )
