 ciated rocks, and showed specimens of brown bituminqtis 

 coal from mines near San Francisco ; asphaltum and petro- 

 leum rocks from Santa Barbara ; also native sulphur from the 

 Geyser springs, and copper ores from the "Union Mine," Ciil- 

 varas County, Cal., and gave an account of their characters, 

 and the amount of copper which they had yielded for the 

 last few years. He also gave an account of the topography 

 and geology of the mining regions in the neighborhood of

E. L. Sturtevant, M. D., was elected a Resident Member. 



March 21, 1866. 

 The President in the chair. 



Thirty-two members present. 



The President read a letter from J. Elliot Cabot, stating 

 that he had been an eye witness to an attack by a Thrasher 

 upon a whale, which took place about three-fourths of a mile 

 from the shore at Nahant, several years since, thus calling 

 into question the supposed harmless nature of this animal. 



Dr. White exhibited casts of the Engis and Neanderthal 

 crania, recently obtainecl by the Society, and made compari- 

 sons with the cranium from Stockton, Cal., giving a resume 

 of the discussions elicited by the recent discoveries in the 

 prehistoric annals of man. 



A letter was read from Mrs. B. D. Greene, presenting to 

 the Society an engraved portrait of Sir W. J. Hooker. A 

 special vote of thanks was passed, both for this picture, and 

 the 39-40th parts of Von Martins' Flora Brasiliensis, which 

 lay upon the table.
