��POPULAR SCIENCE MONTHLY.
��Murray Butler, of Columbia University ; Director Melvil Dewey, University of the State of New York. More than one hundred and fifty international con- gresses, dealing with various subjects of scientific, industrial and social impor- tance, are held this summer in Paris, and form no small part of the interest of the Exposition, supplementing as they do the exhibits, furnishing the theory, as the exhibits set forth the accomplishments, of art and industry. The magnitude of these congresses may be seen from the fact that the thir- teenth International Medical Congress had a registration of over six thousand members, of whom over four hundred were from America.
Friends of scientific investigation and the teaching of science will rejoice at the recent decision in the courts con- cerning the Fayerweather will case. For the eighth time the grant of $3,000,- 000 to the colleges has been confirmed. The case will probably be appealed to the Supreme Court of the United States, but the probability is large that Mr. Fayerweather's wishes will in the end be carried out. At the present time, money left to colleges is likely to be used to a very large extent to promote the progress of science. Required courses in linguistics are decreasing, and the extension of college teaching and university research is largely along- scientific lines. New departments, such as those of physiography, physical chem- istry, anthropology and experimental psychology are being established, while economics and sociology are becoming less speculative and more like the nat- ural sciences in their methods. The college student of to-day gets propor- tionately more training in the professed- ly natural sciences than ever before, and gets scientific training in connection with courses which were once mere ex- ercises in learning the opinions of more or less important people.
We called attention last month to the completion of the plans for an in- ternational catalogue of scientific lit-
��erature, and stated that Great Britain and Germany had each subscribed for forty-five of the three hundred sets that must be sold in order to defray the cost. It is obvious that the United States, with such a large number of libraries and educational institutions, should subscribe for its share of the sets, namely, not less than forty-five. The Smithsonian Institution has provision- ally undertaken to represent the inter- ests of the catalogue in the United States, and will receive promises of sub- scriptions. The catalogue will be issued in seventeen volumes, comprising the following subjects: Mathematics, me- chanics, physics, chemistry, astronomy, meteorology (including terrestrial mag- netism), mineralogy (including petrol- ogy and crystallography), geology, geography (mathematical and physical), palaeontology, general biology, botany, zoology, human anatomy, physical an- thropology, physiology (including ex- perimental psychology, pharmacology and experimental pathology) and bac- teriology. At least one volume will be given to each subject, and it is proposed that not all the volumes shall be issued at once, but in four groups, as soon as possible after the first of January, April, July and October, respectively. The subscription price for a complete set of the whole catalogue, in seventeen vol- umes, is £17, say $85. The volumes will vary in price and can be obtained sep- arately, but it is necessary to secure the guarantee of the sale of forty-five sets in America during the month of September, and all libraries used for scientific research, and those individuals who can afford the cost, should send subscriptions to Dr. Richard Rathbun, Assistant Secretary of the Smithsonian Institution, Washington, D. C.
In the July number of the Monthly Dr. H. C. Bolton gave an account of the radio-active substances which have been found in pitchblende, the chief ore of uranium. The subject continues to excite the interest of both chemists and physicists, though just at present the
