OCHANSK (TABORG), PERM, RUSSIA. No. 116. 



Stone, Ccb. Two fragments, weighing 19 and 142 grams, from a 

 shower which fell on August 30, 1887. Aggregate weight of fall un- 

 certain. Known weight, 169,203 grams. The stone has not been ana- 

 lyzed as a whole, but is of interest in that it has been stated to carry 

 the iron sulphide in the form of crystallized pyrite. The correctness 

 of this identification has, however, been questioned.
