Centipedes near Silver Springs mines in Arizona, are reported to be a foot long. 



Prof. Rogers is delivering a course of popular science lectures in connection

More than 33,000 tons of naphtha is estimated to be floating down the Volga 

 from vessels destroyed by ice in the spring. Great injuries to the fisheries is ex- 

 pected to result. 



In Germany there are now eight schools of forestry, where a training of live 

 years is necessary for students seeking government positions. France supports a

The River Euphrates is reported to be gradually disappearing in the spreading 

 marshes just below Babylon, which have ruined the steamboat channel and are now 

 obliterating navigation for row boats. 



The society of natural history has secured a building site in an eligible loca- 

 tion, — thanks to Mr. and Mrs. E. W. Morse, who have been intimately associated 

 with the society since its organization. 



Mr. Ira J. Gray, recently from the Green Mountain state, has accepted the 

 position of business manager of this journal. This will enable the editor to devote 

 more time to his department, and beneficial results financially are looked for. 



Astronomical photography continues to meet with great favor in France. 

 Since the successful trials of the special photographing telescope at the Paris Ob- 

 servatory, French astronomers have decided to build three dther instruments of 

 the kind. 



Rev. E. L. Greene, who is botanizing on Santa Cruz Island, reports very gratify- 

 ing success in his explorations on this, the one large island on our coast, which 

 remained botanically unexplored. He has found no less than 306 species, some 25 

 of which he expects are new. 



The San Diego Medical Society was organized August 6, with Dr. R. J, Gregg, 

 president and H. T. Risdon, M. D., secretary. The annual meetings are to be 

 held on the first Thursday in August of each year. The monthly meetings are to 

 be held on the first Thursday of each month. 



Singularly flattering reports continue to be made concerning Dr. Domingos 

 Freire's system of preventive inoculation in yellow fever. A late one to the Paris 

 Bilogical Society states that during the three hot months in Brazil ending with 

 February last, 3051 subjects were inoculated in Rio de Janeiro and not one had the 

 fever, whereas in the same districts and houses 278 n on- vaccinated succumbed to the 

 disease. What is more remarkable is that severe cases were inoculated in the sec- 

 ond stage of the disease, and all recovered.
