as light, sound, air, etc., will be destroyed by the prolongation of that same 

 action. 



M. Dumas, corroborates the conclusions of M. Moillefer relative to the ac- 

 tion of ozone on the salts of silver, nickel, manganese, lead, etc. It was hitherto 

 considered that the blackening of silver was due to the action of organic matters. 

 It is the action of ozone that effects the change, and which produces also the vio- 

 let color of manganic acid, hitherto a mystery. 



M. Clemandeau successfully tempers steel, by subjecting iron heated to a 

 cherry redness, to enormous pressure in a mould. The steel is employed for fine 

 tools and telephones. 



BENEVOLENCE FOR SCIENCE.

Editor Kansas City Review : 



Please correct the error contained in your magazine of April, page 734, in 

 the article headed " Benevolence for Science." The $20,000 presented to the 

 California Academy of Sciences, as a permanent fund, the interest of which is to 

 be applied to aid students in original investigations in all branches of Science in 

 California, Nevada, Oregon, and Arizona, was the gift of Mr. Charles Crocker, 

 President of the Southern Pacific Railroad Company. My only connection with 

 the subject was the pleasant duty of announcing the gift to the Academy. 



I may add as a matter of information that since Mr. Crocker made this 

 handsome present, to aid scientific investigation, he and Ex-Governor Leland 

 Stanford, President of the Central Pacific Railroad Company, have jointly pur- 

 chased from Mr. Ward of Rochester, N. Y., at a cost of $16, coo, a scientifically 

 labeled and arrayed collection of more than 7,000 specimens in Palseontology, 

 Zoology and Geology. This collection these gentlemen have also presented to 

 our Academy of Sciences. It is now on exhibition in this city and during the 

 first week was visited by more than 30,000 pupils of the public schools. 



We have no doubt that through the generosity of these gentlemen and other 

 wealthy and public-spirited citizens, our Academy of Sciences will be enabled to 

 enter upon a new career of usefulness in promoting the higher education by 

 scientific investigation. San Francisco has many wealthy citizens who believe, 

 with Lord Bacon, that, while scientific investigation rarely adds to the worldly 

 wealth of its votaries, yet the wealth and comfort of the whole community ap- 

 pear to increase in proportion to the increase in number of the students of 

 nature.
