skins and one elephant were also collected. 

 A large number of birds was secured, including 

 some of the rarest species. Many are game 

 birds, among them guinea-fowls and francolins 

 (which resemble our partridges), and plantain- 

 eaters, crows, bustards, vultures, vulturine 

 guinea-fowl, owls, hawks, kites, secretary 

 birds, horn-bills, pigeons, parrots, sun-birds, 

 flycatchers, etc., are represented. There are 

 also four ostrich eggs. 



The party remained in the field nearly a 

 year, having sailed from New York for Mom- 

 basa on February 18, 1911, not dispersing 

 until about February 15, 1912, at Nairobi. 

 The territory traversed was mostly to the 

 north and east of that covered by Colonel 

 Roosevelt on the earlier Smithsonian expedi- 

 tion, and included the country lying between 

 the northern part of British East Africa and 

 southern Abyssinia. 



THE TWELFTH INTERNATIONAL 

 GEOLOGICAL CONGRESS 



The International Geological Congress, on 

 the joint invitation of the government of 

 Canada, the provincial governments, the De- 

 partment of Mines and the Canadian Mining 

 Institute, will hold its twelfth meeting in 

 Canada during the summer of 1913. It is 

 proposed to hold the meeting in Toronto, be- 

 ginning on or about the twenty-first day of 

 August. The congress will continue in ses- 

 sion for eight days. 



The following topics have been selected by 

 the executive committee as the principal sub- 

 jects for discussion: 



1. The eoal resources of the world. 



2. Diflferentiation in igneous magmas. 



3. The influence of depth on the character of 

 metaliferous deposits. 



4. The origin and extent of the pre-Cambrian 

 sedimentaries. 



5. The subdivisions, correlation and terminology 

 of the pre-Cambrian. 



6. To what extent was the Ice Age broken by 

 interglacial periods? 



7. The physical and faunal characteristics of the 

 Paleozoic seas with reference to the value of the 

 recurrence of seas in establishing geologic systems. 



The executive committee of the Eleventh 

 Congress, held in Sweden, compiled and pub- 

 lished a comprehensive report on the Iron Ore 

 Resources of the World. The present execu- 

 tive committee has undertaken the preparation 

 of a similar monograph on the Coal Resources 

 of the World. In order to make the work as 

 complete as possible the cooperation of all the 

 principal countries of the world has been in- 

 vited. This invitation has met with a cordial 

 response, and it is hoped the volumes will be 

 ready for distribution before the meeting so 

 that they may constitute a basis for discussion 

 at the congress. 



Arrangements have been made for a series 

 of excursions before, during and after the 

 congress which will enable the members to 

 gain a knowledge of the geology and physiog- 

 raphy as well as the mineral resources of 

 Canada. 



The honorary president of the congress is 

 the Duke of Connaught, governor general of 

 the Dominion of Canada. The president is 

 Dr. Frank D. Adams, dean of the faculty of 

 applied science and Logan professor of geol- 

 ogy, McGill University, Montreal, and the gen- 

 eral secretary is Mr. R. W. Brock, director of 

 the Geological Survey of Canada. 



SCIENTIFIC NOTES AND NEWS 

 At the celebration of the seventy-fifth an- 

 niversary of the foundation of the University 

 of Michigan on June 27, the degree of doctor 

 of laws was conferred on Dr. Henry S. Car- 

 hart, professor of physics there from 1886 

 until his retirement in 1909 as emeritus pro- 

 fessor. As already noted in Science, the de- 

 gree of doctor of science has been conferred 

 on Dr. Carhart by Northwestern University, 

 where he was professor of physics from 1872 

 to 1886. 



Yale Ujs'iversity has conferred the degree 

 of doctor of science on Professor H. T. Eddy, 

 dean of the graduate school of the University 

 of Minnesota. Professor Eddy, who is presi- 

 dent of Sigma Xi, gave one of the addresses 

 of the joint meeting of the members of the 

 societies of Phi Beta Kappa and Sigma Xi.
