I read in an Australian paper, that a white boy, who was bitten in the finger by a dead-adder, had so much presence of mind, as to chop it off with his pocket-knife. The finger had afterwards to be regularly amputated, but the boy’s life was saved. An interesting discussion occurred as to the characteristics of various species of trees.

The following was received from Prof. W. H. Brewer, in reference to the occurrence of fossils in the auriferous slates of California: Occurrence of Fossils in the Auriferous Slates of California. BY PROF. W. H. BREWER. I find in published _Proceedings of the Academy_, just received, that some remarks 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 California, 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.
