work on bacteriology, parasitology, imnninol- 

 ogy and study of infectious diseases carried 

 out and published in Japan during the pre- 

 ceding year. The work consisted of the dis- 

 covery of the cause of the infectious jaundice, 

 which prevails endemically not only in Japan 

 but also in other countries. The causative 

 agent has been discovered to be one of the 

 species of spirochetes. 



In accordance with plans approved by Sec- 

 retary of the Interior Lane, the investigation 

 of the mineral resources of Alaska by the Geo- 

 logical Survey will be continued this year by 

 12 parties. Congress has recognized the ne- 

 cessity of preparing in advance for the sur- 

 vey of this difficult field by including the ap- 

 propriation for its continuation in the urgent 

 deficiency act, which was approved on Feb- 

 ruary 28. This prompt action makes it pos- 

 sible to plan the work in advance of the 

 opening of the field season and to carry out 

 the plans efficiently and economically. The 

 work to be done this year includes a detailed 

 survey of the region tributary to Juneau, 

 Juneau, which is the most important quartz 

 camp in Alaska. A continuation of the study 

 of the mineral resources of the Ketchikan dis- 

 trict, where there are important gold and cop- 

 per mines, is also planned. The investigation 

 of the water powers of southeastern Alaska 

 will also be continued. Only one party will 

 be employed in the Copper Eiver region. Two 

 parties will work in Prince William Sound. 

 Four parties will make surveys in the region 

 directly or indirectly tributary to the govern- 

 ment railroad under construction. One of 

 them will study the new Tolovana placer dis- 

 trict and also make some supplementary in- 

 vestigation of the Fairbanks lode district. 

 The geologists of this party will later visit the 

 Nome district. A detailed geologic survey 

 will be made of the western part of the JSTenana 

 coal field, which is adjacent to the route of 

 the government railroad. Two other parties 

 will be employed in carrying reconnaissance 

 surveys westward from the railroad route to 

 the Kantishna placer and lode district. It is 



also proposed to make surveys of the lower 

 Yukon, including the Marshall placer district. 



It is stated in Nature that at the recent an- 

 nual meeting of the Paris Academy of Sci- 

 ences, the president, M. Gaston Darboux, gave 

 an account of the careers of men, for the most 

 part young, to whom prizes of the academy 

 had been awarded, but who have fallen in the 

 service of their country. M. Marty (Fran- 

 ccEur prize), killed September 10, 1914, at the 

 battle of the Meuse, was distinguished by his 

 contributions to mathematics. M. E. Mar- 

 celin (Hughes prize), killed near Verdun, in 

 September, 1914. His work on kinetic physi- 

 cal chemistry was remarkable, both in theoret- 

 ical treatment and on the experimental side. 

 M. Marcel Moulin (Gaston plante prize), killed 

 at the battle of the Marne, September 6, 1914, 

 founded the Institute of Chronometry at 

 Besangon. M. Viguier (Cahours prize), killed 

 at Beausejour, March 5, 1915, made his mark 

 in the field of organic chemistry. M. Albert 

 de Eomeu (Delesse prize), killed January 12, 

 1915, at Bucy-le-Long, near the Aisne, was the 

 author of noteworthy petrographie work. M. 

 Rene Tronquoy (Joseph Labbe prize), wounded 

 and missing, February 20, 1915, was proposed 

 for the Cross of the Legion d'honneur, and was 

 well known for his mineralogical work. M. 

 Blondel (Saintour prize), wounded and miss- 

 ing, September S, 1914, at Fere-Champenoise, 

 was distinguished for his work on the theory 

 of tides. M. Georges Lery (Gustave Eoux 

 prize), killed at the battle of the Marne, Sep- 

 tember 10, 1914, was a geometer of great prom- 

 ise. Lieutenant-Colonel Arnaud (Henri Bec- 

 querel prize), aged sixty years, died of illness 

 contracted on active service. M. Jean Merlin 

 (Becquerel prize), on the staff of Lyons Ob- 

 servatory, killed at Arrozel, August 29, 1914. 

 He was known by his researches dealing with 

 the theory of numbers. M. Eabioulle (Bec- 

 querel prize), on the staff of the Algiers Ob- 

 servatory, killed in the battle of the Aisne, 

 September 21, 1914. M. Jean Chatinay 

 (Fanny Emden prize), killed at Vermelles, 

 October 15, 1914. Commandant Henri Batail-
