NICOTINE POISONING; EXPERIMENTS; FACTS. 



It is upon the effects of the tobacco-habit on 

 body and mind that this whole question hinges. 

 And these effects must be determined by the opin-

 experience and observation, with such facts as 

 corroborate them. It has therefore been deemed

 and to summon many witnesses as to the various 

 diseases, bodily and mental, charged to the ac-
