crystals were found in the neighborhood of Grass Valley, Cal., 

 in placer gold mines and, although somewhat waterworn, are re- 

 ported to be of great size and clearness. One is said to weigh 

 a ton. The paper was discussed by Messrs. Levison and 

 Kemp. 



The second paper related to the exhibition of recent acces- 

 sions of rare minerals, loaned for the purpose, by Professor A. 

 J. Moses. Among the rest a large specimen of cellular rock 

 with coats of Huantahajite, the whole being 8 inches square, 

 was of particular interest. In the absence of Professor Moses 

 the specimens were commented on by the Chairman and by 

 Professor Chester. 



The third paper was by Professor F. D. Chester, entitled 

 Krennerite from Cripple Creek, Col. The speaker re- 

 marked on the raritv of the mineral and described his g-ood for- 

 tune in obtaining a specimen with ciystals capable of being 

 measured, which were now being studied by Professor Penfield 

 of Yale. The paper led to a considerable discussion upon the 

 occurrence of the telluride ores, by Messrs. Caswell, Chester, 

 Kunz and Kemp. 



Professor Kemp then exhibited some specimens of the Nephe- 

 line Syenite from Dungannon, Ont., which he had received from 

 Mr. F. J. Pope, and which showed crystals of Corundum of 

 large size, forming an original mineral in the rock. 



Dr. W. G. Levison exhibited some microscopic mounts of 

 minerals in small pasteboard boxes. 



A paper by Stuart Weller, entitled Description of De- 

 vonian Crinoids and Blastoids from Milwaukee, Wis., was 

 read by title. 



On motion the meeting adjourned.
