took place. Following up this line of reasoning, every peculiarity 
of the genesis and structure of an auriferous or gold-bearing quartz 
vein can be explained, by presuming that the deposition of the 
quartz came from water which held alkaline silicates, salts and 
acids in solution, and precipitated them upon condensation of this 
aqueous solution, which was then followed with crystalization of 
the silica into quartz, and the silicated gold into metallic gold. 
And, in addition to these reactions, the associated minerals found 
in the veins of quartz with gold, may have evidently been derived 
from the very same sources. — Dr. Willis Everette. 
It is to be hoped that the following extract from the 
Cleveland Leader does not represent the average condition of 
geological knowledge in the great state of Ohio, or at least among 
its legislators. It has long been known that the wise men came 
from the East, and Sidney Smith once said that he never realized 
this till he went west. It would seem that "gassing" should be 
the chief employment of the state geologist according to Mr. 
Brown. 
Columbus, March 18. 
Representative Griffin, of Lucas, has received a letter from repre- 
sentative Brown, of Hancock, asking for legislative action of a rather 
startling nature. Mr. Brown requests that Mr. Griffin introduce a reso- 
lution providing for an investigation of Hon. Edward Orton, state geol- 
ogist, for stating in his last report that natural gas is failing in north- 
western Ohio. 
Dr. Ottokar Feistmantel of Prague, died on the 10th of 
February in the 43d year of his age. 
Dr. Joseph Leidy, the eminent paleontologist, of Philadel- 
phia, president of the Philadelphia Academy of National Sciences, 
died April 30, at his residence in that city.
