The opening (January) number of volume 

 5 of the Transactions of the American Mathe- 

 matical Society contains the following papers : 



L. E. Dickson : ' The Subgroups of Order a 

 Power of 2 of the Simple Quinary Orthogonal 

 Group in the Galois Field of order p" = W ± 3.'

 Eypercomplex Number Systems.' 



E. GouRSAT: 'A, Simple Proof of a Theorem in 

 the Calculus of Variations (Extract from a Letter 

 to Mr. W. F. Osgood).' 



The American Naturalist for November is 

 a little belated. It contains the second of the 

 papers on ' Adaptations to Aquatic, Arboreal, 

 Fossorial and Cursorial Habits in Mammals,' 

 this being by Louis I. Dublin on ' Arboreal 

 Adaptations.' In a few instances it would 

 seem that the writer may not have distin- 

 guished between physiological adaptation and 

 morphological characters. D. T. MacDougal 

 considers at some length 'Mutation in Plants,' 

 some of his conclusions being that new types 

 of specific rank have arisen in (Enothera by 

 discontinuous variation, that natural selection 

 is universally prevalent is certainly disproved 

 and that nothing in the nature of living or- 

 ganisms demands that all species should have 

 originated in the same manner. S. E. Meek 

 presents a paper on the ' Distribution of the 

 Fresh- Water Fishes of Mexico,' considering 

 that four distinct fish faunas are present, and 

 that their origin and number of species are 

 as follows : From the Colorado River, 9 ; from 

 the Eio Grande, 80 ; from the Lerma, 49 ; and 

 from Central America, 246. The final paper, 

 by Pehr Olssdn-Seffer, is on the ' Examina- 

 tion of Organic Remains in Postglacial De- 

 posits,' particularly in peat, and contains very 

 good and full directions as to the methods 

 and apparatus necessary. 



The Popular Science Monthly for January 

 has for a frontispiece a portrait of the late 

 Herbert Spencer from a bust made when he 

 was seventy-six. The first article is ' A Case 

 of Automatic Drawing,' by William James, 

 with numerous illustrations of the curious 

 pictures made by the subject. In ' The Col- 

 lege Course ' John J. Stevenson makes a plea 

 for a return to the college with a course of 

 four years, mainly compulsory, and in ' The 

 Functions of Musemns ' F. A. Bather suggests 

 such a division of the material as would make 

 it most available for the general student, the 

 special student and the general visitor. T. A. 

 Jaggar describes ' The Eruption of Pele, 

 July 9, 1902 ' ; Allan McLaughlin discusses 

 ' Immigration and the Public Health,' sug- 

 gesting more carefully drawn laws on the 

 subject, and Amanda Carolyn Northrop con- 

 siders ' The Successful Women of America,'
