of Another Surface,' by L. P. Eisenliart ; ' On 

 Groups Generated by Two Operators,' by G. A. 

 Miller ; ' A Curious Approximate Construction 

 for ^,' by G. Peirce ; Review of Manning's 

 Non-Euclidean Geometry, by J. L. Coolidge, 

 and of Bianchi's Differential Geometry, by 

 J. K. Whittemore ; 'Notes'; 'New Publica- 

 tions ' ; ' Tenth Annual List of Papers Read 

 before the Society and Subsequently pub- 

 lished ' ; and a sixteen-page Index of the 

 Volume. 



The Popular Science Monthly for July opens 

 with an important article on 'The Transniis- 

 sion of Yellow Fever by Mosquitoes,' by George 

 M. Sternberg, detailing the long and careful 

 series of experifnents which seem to clearly 

 point out the mosquito as the active agent 

 in the spreading of this disease. Incidentally 

 it may be noted that no less than eighteen men 

 voluntarily exposed themselves to the disease 

 in order to test the theory of its diffusion. 

 Under 'Climate and Carbonic Acid,' Bailey 

 Willis discusses the evidence in favor of the 

 theory that the glacial epochs have been caused 

 by the absorption of carbonic dioxide from the 

 atmosphere, permitting the radiation of heat 

 and lowering the temperature of the earth's 

 atmosphere. A translation is presented of the 

 article on 'The Peopling of the Philippines,' 

 by Rud. Virchow, and Havelock Ellis con- 

 tinues his ' Study of British Genius, ' this in- 

 stalment being devoted to pathology, from 

 which it appears that there is a special connec- 

 tion between genius and gout. Edward L. 

 Thorndike treats of ' The Intelligence of Mon- 

 keys,' deciding that they carry the animal 

 method of learning beyond a point reached 

 by any other of the lower animals. ' Cocaine 

 Analgesia of the Spinal Cord ' is discussed by 

 Smith Ely Jelliflfe, and Henry A. Pilsbry consid- 

 ers ' The Evidence of Snails on Changes of 

 Land and Sea,' while Frank Waldo describes 

 the work of ' The Blue Hill Meteorological Ob- 

 servatory,' which he considers the most suc- 

 cessfully conducted meteorological observatory 

 in America. The final article is on the organ- 

 ization and aims of 'The American Association 

 for the Advancement of Science ' apropos of its 

 coming meeting in Denver. There is much in- 



teresting reading to be found in ' The Progress 

 of Science.' 



In The American Naturalist for June, W. M. 

 Wheeler presents the first part of a paper on 

 ' The Compound and Mixed Nests of Ameri- 

 can Ants.' Glover M. Allen describes 'The 

 Louisiana Deer ' as a subspecies under the name 

 of Odoccelus virginianus louisianse. It is a rather 

 curious fact that the antlers of the type of 

 the subspecies and of the two forms shown for 

 comparison are all abnormal. R. W. Shufeldt 

 gives an excellent paper ' On the Osteology and 

 Systematic Position of the Screamers ' ( Pala- 

 medea : Chauna), in which their points of 

 agreement and disagreement with the ducks 

 and fowls are well shown. ' Normal Respira- 

 tion and Intramolecular Respiration ' are dis- 

 cussed by George J. Peirce, and Abram V. 

 Mauck contributes an article ' On the Swarm- 

 ing and Variation in a Myriapod ' (Fontaria vir- 

 giniensis). The fifteenth instalment of the fine 

 series of ' Synopses of North American Inver- 

 tebrates ' is by Hubert L. Clark and is devoted 

 to the Holothurioidea. ' Editorial Comment ' 

 and the customary reviews complete the num- 

 ber. 



The Auk for July is mostly devoted to syste- 

 matic papers : ' Ben dire' s Thrasher,' by Herbert 

 Brown ; ' Birds of the Black Hills,' by Merritt 

 Cary; 'Unpublished Letters of William Mac- 

 Gillivary to John James Audubon,' by Ruthven 

 Deane ; ' The Resident Land Birds of Bermuda,' 

 by Outram Bangs and Thomas S. Bradlee, con- 

 taining descriptions of several new species ; ' A 

 New Ground Dove from Western Mexico,' by 

 Outram Bangs ; ' The Monterey Hermit Thrush, ' 

 by Joseph Grinnell ; ' The Winter Birds of Pea 

 Island, North Carolina,' by Louis B. Bishop, a 

 list of 42 species, and 'A New Sharp-tailed 

 Finch from North Carolina,' by Louis B. Bishop. 

 The ' General Notes ' and ' Reviews of Recent 

 Literature ' are very full.
