342 PROCEEDINGS OF THE CALIFORNIA 



gat, by Major S. S. Lyon, formerly of the Kentucky Geological 

 Survey. Major Lyon being present, at the request of the Presi- 

 dent, gave an account of this interesting locality, which is one long 

 known to explorers. He stated that the Salt Mountain lies on both 

 sides of the Muddy River, and rises 400 feet above that stream. 

 The locality is about thirty miles northeast of Colville, and twenty 

 from the Colorado. Major Lyon also gave some facts in regard to 

 the geology of the vicinity of Pahranagat, where he had been re- 

 siding for some months past. 



Professor Whitney presented two analyses of ores from the Corn- 

 stock Lode, Virginia City, Nevada, made by Professor Domeyko, 

 of Santiago, Chile, and communicated by Mr. Remond, who is now 

 residing in that place. They are as follows :

Gold 1.10 0.18

The name of the mine from which they were taken was not 

 given. 



Mr. Yale brought up the subject of the gold mines in Africa, 

 supposed to be worked by the Emperor Napoleon III, and kept 

 secret from the world in general. A discussion ensued, in the 

 course of which Professor Whitney and Mr. Ashburner expressed 

 their doubts as to the possibility of the locality of any extensive 

 mining operations being long concealed, and their disbelief in the 

 truth of newspaper statements to this effect.
