Stone, Cu. Weight, 83 grams. Fragment with crust; fell Sep- 

 tember 22, 1886. Three stones fell, one of which was not recovered, 

 having fallen in a marsh; a second passed into the hands of a 

 countryman, and its weight not determined. The third, which 

 passed into the possession of the mineral cabinet of the Institute of 

 Forestry, St. Petersburg, weighed 1.9 kilos. The stone contains car- 

 bon in both the amorphous form and that of microscopic diamond, 

 and is therefore of unusual interest.
