NATIONAL GEOGRAPHIC MAGAZINE $3.00 a Year 25 Cents a Number THE POPULAR SCIENCE MONTHLY Edited by Professor J. McKEEN CATTELL of Columbia University With the Co-opera/ion of Leading American Men of Science IT is fortunate for American science that America's leading scien tific periodical should continue to be published under favorable auspices. Since its establishment by Messrs. D. Appleton & Company and the late Dr. E. L. Youmans in 1872, this journal has been so important a factor in the distribution of scientific knowledge that it seems almost useless to call attention to the great names which have been associated with it during the past twenty-eight years-to such names as those of Darwin, Huxley, Spencer, and many others, to whose works many Americans were first introduced through its pages. In the future, as in the past, THE POPULAR SCIENCE MONTHLY will afford an accurate and authoritative record of the progress of contemporary science, and besides being indispensable to the pro fessional investigator, it will seek to secure that popular interest and support which are of essential importance to the cause of scientific progress. THE NEW EDITOR Dr. JAMES McKEEN CATTELL, Professor of Psychology in Columbia University, and hitherto Editor of Science, occupies a well-known position of distinction among American Men of Science. Dr. Cattell is thoroughly familiar with the needs of the general public, and will have these in view as well as those of special scien tific knowledge. He will be assisted in the editorship by Dr. E. L. Thorndike, of Columbia University.
