SCIENCE. 



[Vol. XVI. No. 387 



M.D. The medical editor announces that hereafter more space 

 will be given to questions of diet, in the department of "Nursery 

 Problems," this subject seeming to be of never-ending interest 

 and importance to the magazine's readers. 



— The United States Department of Agriculture has issued 

 Parts I., 11., and III. of a "Bibliography of the More Important 

 Contributions to American Economic Entomology." As far as 

 published, this bibliography consists of an octavo volume of 454 

 pages, devoted to the writings of Benjamin Dann Walsh and 

 Charles Valentine Riley. The importance of these writings can 

 be appreciated when one considers that this index to them must 

 have cost the government several thousand dollars. Samuel 

 Henshaw is the editor of the work. 



— A copy of the seventh edition of Bloxam's "Chemistry, In- 

 organic and Organic," was recently received. Among the new 

 matter introduced is an account of Raoult's method for the deter- 

 mination of molecular formulae, and Fischer and Tafel's investi- 

 gations on the synthesis of sugars. The chemistry of vegetation 

 has also been rewritten to suit more modern views. The portions 

 relating to explosives, to which the book to some extent owes its 

 reputation, have been duly revised. The publishers in this coun- 

 try are P. Blakiston, Son, & Co., Philadelphia. 



— In the "Proceedings of the Royal Geographical Society for 

 March, 1889," was published a paper on "The Selkirk Moun- 

 tains," by W. S. Green. This paper was accompanied by a map 

 giving the results of Mr. Green's surveys in this little-known re- 

 gion. As the space available in the "Proceedings" was naturally 

 limited, it seemed desirable that a more extended report of the 

 trip should be published; and this we have in "Among the Sel- 

 kirk Glaciers," a recent publication of Macmillan. The author 

 first had his attention drawn to the Selkirks by the reports of two 

 friends who attended the meeting of the British Association in 

 Montreal in 1884, and later took part in the excursion west on the 

 then uncompleted Canadian Pacific Railway. It was not till the 

 summer of 1888, however, that Mr. Green, accompanied by a friend 

 well tried as a travelling companion, made his expedition. One 



might suppose that a country reached by railway would offer 

 little to explorers; but the difficulties presented by the Selkirk* 

 have debarred many travellers from venturing among them, so 

 that we have in this book a valuable contribution to knowledge, a& 

 well as a well-written book of travel. 



— "The Advancement of Science," by E. Ray Lankester, re- 

 cently published by Macmillan, is a collection of essays printed in 

 the various English reviews during the last ten or twelve years. 

 The object of some of them was to help on government aid to 

 science, and in general they were written with the purpose of 

 informing the public of scientific progress. Naturally some state- 

 ments of fact and theory are now a little out of date, but as a 

 record of progress they have their value. The various titles ar& 

 "Degeneration: a Chapter in Darwinism;"' "Biology and the 

 State;" "Pasteur and Hydrophobia;" "Examinations;" "The 

 ScientiQc Results of the International Fisheries Exhibition, Lon- 

 don, 1883;" "Centenarianism;" "Parthenogenesis;" "A Theory of 

 Heredity;" and "The History and Scope of Zoology." 



— Among the contributions in the forthcoming numbers of the 

 English reviews for July, issued in this country in the original Eng- 

 lish form by the Leonard Scott Publication Company, New York, 

 wiU be a paper recounting the particulars of a journey to Lhasa, 

 the capital of Thibet, made by the Indian Buddhist scholar Sarat 

 Chandra Das. This narrative, which deals with an almost un- 

 known part of the world, has long been suppressed, in view of the 

 information it gives to possible British rivals in Asia. Mr. Ed- 

 ward Bellamy will also have a paper in this number. The Fort- 

 nightly Review will contain, in addition to the usual variety of 

 articles, one by Madame James Darmesteter, on "The Bookmen 

 of Paris in the Fourteenth Century." 



— The Magazine of American History opens its twenty-fourth 

 volume with the July number. A portrait of Sir William Black- 

 stone serves as frontispiece. Its pertinence is apparent to whoso- 

 ever reads the leading article, "The Golden Age of Colonial New 

 York." Mrs. Lamb has given a picture of the little metropolis of 

 the province under kingly rule in 1768, conducting the curious
