ARSENIC AND BICHLORIDE OF MERCURY. 973 



Arsenic also, when applied to a fresh wound, 

 or taken into the stomach, causes short and hur- 

 ried respiration, coldness of the surface, a pale 

 or livid hue of the face, feeble pulse, vomiting, 

 faintness, stupor, convulsions, and death, when 

 the stomach is found to exhibit decided marks of

 other symptoms of constitutional derangement.

 strength, partial paralysis, convulsions, and death. 

 The salts of copper are also followed by rigors, 

 violent head-ache, loss of sensibility, vomiting, 

 cramps, paralysis, and death. 



Corrosive sublimate produces nearly the same 

 effects as arsenic, with still more decided marks 

 of inflammation in the stomach. Like the chlo-

 of the blood, according to Magendie, who recom-

 any of these poisons have been swallowed. He 

 also found that seven grains of oxalic acid,
