VEGETABLE POISONS. 205

 serious consequences to the animal frame in 

 general ; though, as upon a former occasion, we 

 have observed, very extraordinary liberties are 

 frequently taken with it, the operation of which 

 it possesses, in many instances, a wonderful power 

 of resisting, and of still preserving its healthy 

 functions to a very late period of life. 



We have deemed it necessary to trouble you 

 with this short account of the grand intestinal 

 canal, because when poison has been received 

 into the stomach, there is no part of the tube, 

 which does not organically or sympathetically 

 partake of the injury ; and you will the more 

 readily understand how in such instances the 

 more distant organs become affected, and what 

 are the morbid appearances likely to be pre- 

 sented upon dissection, when cases of poisoning 

 become the subject of judicial investigation. 



Should we have been so fortunate as to have 

 made ourselves clearly understood in this very 

 brief account of the structure and functions of 

 the digestive organs, we may with advantage

 which produce their effect on the animal system 

 by being previously received into the stomach. 



These substances, which are derived from the
