not produce their deleterious effects until they have passed into 

 the circulation. 



2. All of these poisons occasion disorder of the functions of 

 the heart, brain, and alimentary canal j but they do not all 

 affect these organs to the same relative degree. 



>. Arsenic operates on the alimentary canal in a greater 

 degree than either the emetic tartar, or the muriate of barytes. 

 The heart is affected more by arsenic than by the emetic tar- 

 tar, and more by this last, than by the muriate of barytes. 



4. The corrosive sublimate, when taken internally in large 

 quantity, occasions death by acting chemically on the mucous 

 membrane of the stomach, so as to destroy its texture j the 

 organs more immediately necessary to life being affected in con- 

 sequence of their sympathy with the stomach. 



Mineral and j n making the comparison between them, we observe, that 



vegetable poi- 



sons om- the effects of mineral, are less simple than those of the gene- 



pareJ. rality of vegetable poisons ; and when once an animal is 



affected by the former, there is much less chance of his 



recovery, than when he is affected by the latter.

AN observing gardener, on ascending the high mountains of 

 our temperate region, is immediately struck with the vi- 

 mountain in gour and luxurious appearance of their vegetation. The plants he 

 temperate re- j ias geen m t j ie adjacent plains are changed in size, aspect, and 

 form, so that he hardly recognises the most common. Their 

 . stems are elevated, their flowers larger, even the leaves of the 

 trees have acquired a size, which makes him doubt the identity
