Stone, Kc. Two fragments weighing, respectively, 33 and 261 

 grams. Fell April 7, 1891. (PI. 26.) Total weight of fall, 27 kilo- 

 grams, or 59.4 pounds. One of the carbonaceous chondrites, and of 

 interest in that it carries the rare calcium sulphide oldhamite. The 

 chemical composition, as determined by J. E. Wliitfield, is as follows:
