 MONTHLY 



3 DOLLARS A YEAR 2 5 CENTS A NUMBER 



Edited by Professor J. McKeen Cattell 



THE POPULAR SCIENCE MONTHLY for February is a number that 

 should be in the hands of every one who is interested in science. The 

 opening article, on the " LIFE AND WORK OF HUXLEY," by Lord 

 Avebury — perhaps better known in America as Sir John Lubboclc — is an 

 extremely interesting account of the great naturalist by one of his most 

 intimate friends. The publication of Huxley's "Life and Letters" makes 

 this article particularly timel3^ Dr. George M. Sternberg, Surgeon-General 

 of the U. S. Army, contributes an account of malaria and the recent work 

 demonstrating the connection of tliis disease with mosquitoes — perhaps the 

 most important scientific advance sii;i,ce the discovery of the X-rays, 

 here described by the leading American authority. Mr. Havelock Ellis, 

 editor of the "Contemporary Science Series," begins a series of articles on 

 "British Men of Genius," an extremely interesting statistical and scientific 

 study, now first made possible by the publication of the " Dictionary of 

 National Biography." Professor Simon Newcomb contributes an install- 

 ment of his " Chapters on the Stars," treating the clustering of the stars 

 and the Milky Way. Professor Newcomb is probably the most eminent 

 American man of science, while at the same time he possesses rare literary 

 ability in presenting clearly and simply the great principles of science. 

 Other articles in the number are an account of important contributions by 

 Professor T. C. Chamberlin, to a theory of the glacial period, by Mr. Bailey 

 WiUis, of the U. S. Geological Survey; a description of the New York 

 Aquarium, with illustrations by Professor Charles L. Bristol, of New York 

 University ; a description of the Dolmens of Rocknia, by Professor A. S. 

 Packard, of Brown tjniversity, and an account of the way in which the 

 weather is treated and mistreated in the newspapers, by Mr. H. M. Watts, of 

 the Philadelphia Press. The number contains, as usual, departments devoted 

 to correspondence, to scientific literature, and to notes on the progress of 

 science.
