berry, exert only a local influence on the nerves, 

 and produce no general effects unless they enter 

 the circulation. Sir Benjamin Brodie also found, 

 that when the woorara poison was applied to a 

 wound in the fore foot of a rabbit, after all the 

 nerves of the anterior extremity in the axilla of the 

 same side were divided, the action of the poison 

 was not prevented : but that when a ligature 

 was placed around the leg of a rabbit, leaving 

 out the principal nerves, no bad effects were 

 produced by the poison, until the ligature was 

 loosened, when they immediately ensued. (Phil. 

 Trans. 1811, p. 178; 1812, p. 107.) He also 

 found, that muriate of bary tes, tartar emetic, and 

 corrosive sublimate, produced the same effects 

 when applied to fresh wounds as when taken into 

 the stomach, that, like arsenic, alcohol, oil of 

 tobacco, oil of almonds, and other narcotic poisons, 

 they are absorbed into the circulation, and pro- 

 duce their morbid effects by diminishing the 

 voluntary power of the brain over the function of 

 respiration. He further ascertained, that after 

 respiration and all the visible actions of life in a 

 rabbit had been arrested by a dose of the essential 

 oil of almonds, they were restored by keeping up 

 artificial respiration for sixteen minutes, and the 

 animal appeared perfectly well in two hours.*
