California. 



BY PROF. W. II. BREWER. 



I find in published Proceedings of the Academy, just received, that some re- 

 marks I made at the meeting of October 3d, 1864, were not published, that I 

 wish recorded. 



In the discussion on the occurrence of fossils in the auriferous rocks of Califor- 

 nia, I stated that fossils had been found by the Geological Survey, in the rocks 

 associated with gold, along a line nearly 300 miles in length, extending from Pitt 

 River to the Mariposa Estate ; that the associated rocks of similar age, bearing 

 gold, had been traced upwards of 550 miles in the Sierra Nevadas, and that 

 Jurassic fossils had been found in the " auriferous slates," along a belt of 200 

 miles of this distance, and that both Jurassic and Triassic fossils had been found 

 in considerable numbers near and in Genesee Valley, Plumas Co.
