McKEEN CATTELL WITH THE CO-OPERATION OF THE LEADING AMERICAN MEN OF SCIENCE For more than thirty years THE POPULAR SCIENCE MONTHLY has been the standard scientific magazine of the world. It should be found in every library, in the hands of scientific men, in the offices of physicians and other professional men and indeed in every home of intelligent and cultivated people. The publishers do not need to insist on the merits of the journal for these are acknowledged by all who are competent to judge. The following may be quoted as typical opinions: "Especially important in free public libraries."-J. S. BILLINGS. Director of the Consolidated Libraries, New York City. "Of great utility."-S. P. LANGLEY, Director of the Smithsonian Institution. "Most valuable in keeping busy men abreast of the more important advances of science."—A. W. GREELY, General, U. S. A. "The newest and best that can be said on any subject."- WILLIS L. MOORE, Chief of the U. S. Weather Bureau. "It has done more for the diffuson of scientific information in this country, during the past twenty-five years than any other one agency."-GEORGE M. STERNBERG, Surgeon General, U. S. A. "The most instructive and most enjoyable scientific journal which I have seen anywhere, here or abroad."-HUGO MUNSTERBERG, Professor of Psychology, Harvard University. "I refer to it so constantly that we shall soon need a new set."-E. A. STRONG, Professor of Physics and Chemistry, State Normal College, Ypsilanti, Mich. "It has few rivals and no equal in the educative service it has done for the American people. A complete set of the volumes thus far published is both a history of science for the period covered and at the same time a pretty complete cyclopedia of natural_science. There is nothing to fill its place, and to carry it on is a benefaction to the public."-W. T. HARRIS, U. S.
