382 ON THE ZEHR MOHEREH, 



IX. 



ON THE 



ZEHR M O II E R E H, 

 OR SNAKE STONE. 



By captain J. D. HERBERT. 



XN the 13th Volume of the Transactions of the Asiatic Society, is a paper, 

 giving the results of an Analytical Examination of what are called Snake 

 Stones, by Dr. Davy. The author has not stated by what appellation those 

 which he examined were distinguished, but from the remarks appended by the 

 Secretary, it is presumed that they are, if not identical, yet to be classed with 

 the Bezoar of Europe, or what is more commonly in India known as the Zehr 

 Mohereh^ or Poison Stone. The Zehr Mokereh is stated, in the appended 

 remarks, to be of two different kinds, the one of animal, the other of mineral 

 origin. The former are supposed to be calculous concretions formed within 

 the stomach or intestines of an animal, and are of rather various composition. 

 M. Vauquelin analysed several, and there is a short account of his results un- 

 der the article Bezoar, in Ure's Chemical Dictionary. The Bezoar is of a 

 concentric lamellar structure, as might be expected from the manner in which 

 it is formed. The Mineral Bezoar is stated, in the above paper, to be of simi- 

 lar structure and appearance, only differing in its origin.
