ting currents, etc. In light there are the re- 

 nowned discovery and theory of the concave 

 grating and the long series of investigations 

 made in the field of spectroscopy. List of 

 wave-lengths will not be reprinted in this vol- 

 ume, as they are readily accessible elsewhere; 

 and any subscriber to this volume may obtain 

 by application to the Johns Hopkins Press, 

 Baltimore, a copy of Rowland's 'Preliminary 

 Table of Solar Wave-lengths.' There will be, 

 further, a description of Rowland's ruling en- 

 gine, used for the making of gratings, details 

 of which have never before been published. 



The Memorial Address of Professor Men- 

 denhall; published in Science, and a portrait 

 of Professor Rowland will also be included. 



The volume will be printed in royal octavo, 

 bound in cloth, and will contain between six 

 and seven hundred pages. The price set is 

 five dollars per copy for orders sent in advance 

 of publication. 



Orders may be sent to Professor Joseph S.

THE INTERNATIONAL CATALOGUE OF 

 SCIENTIFIC LITERATURE* 



The Third International Gonference on this 

 subject, held in London during June, 1900, 

 after considering the questions left in abey- 

 ance by the two previous Conferences, decided 

 to publish an annual book catalogue arranged 

 according to both an author and a subject 

 index of the following named sciences : Mathe- 

 matics, Mechanics, Physics, Chemistry, Astron- 

 omy, Meteorology (including Terrestrial Mag- 

 netism), Mineralogy (including Petrology and 

 Crystallography), Geology, Geography (Mathe- 

 matical and Physical), Paleontology, General 

 Biology, Botany, Zoology, Human Anatomy, 

 Physical Anthropology, Physiology (including 



* Abstract from a paper on the International 

 Catalogue of Scientific Literature read before the 

 American Philosophical Society, April 4, 1902, by 

 Cyrus Adler, Ph.D. (For fuller history see Sci- 

 ence, August 6, 1897, June 2 and 9, 1899. Also 

 reports of the First, Second and Third Interna- 

 tional Conferences, published by the Royal Society, 

 of London.) 



Experimental Psychology, Pharmacology and 

 Experimental Pathology), and Bacteriology. 



Government aid was ofEered by many of the 

 , countries represented by delegates. The cata- 

 logue was to consist of an index to all original 

 contributions to science published after 

 January 1, 1901. Regional bureaus were to be 

 established in the several countries charged 

 with the duty of furnishing to the Central 

 Bureau an index of the scientific literature of 

 their respective countries. The price of the 

 catalogue was fixed at $85 per annum for the 

 17 annual volumes, subscriptions to be made 

 for a period of five years. At the present time 

 the affairs of the catalogue are as follows : The 

 United States Government having as yet failed 

 to contribute toward the support of a regional 

 bureau, the Smithsonian Institution has tem- 

 porarily undertaken the work. 



The equivalent of over 71 complete sets, rep- 

 resenting over thirty thousand dollars, have 

 been subscribed for in the United States. 



In February the Central Bureau reported 

 that over fifty-one thousand catalogue slips had 

 been received from the Regional Bureaus. 



The first parts of Chemistry and Botany will 

 be published during the present month, to be 

 shortly followed by parts of Physios and 

 Physiology. It was found necessary to pub- 

 lish these first volumes in two parts. The next 

 publications will be the complete volumes of 

 Mathematics, Astronomy, Meteorology and 

 Bacteriology for 1901. Single volumes may be 

 subscribed for at their proportional value. A 

 provision has been made for those desiring a 

 card index to print some of the sets on one 

 side of the leaf only in order that the separate 

 entries may be mounted on cards. The charge 

 for the vokimes so printed will be about one' 

 sixteenth in addition to the cost of the regular 

 form.

 The degree of LL.D. was conferred on Lord

 that the University has held a special assem-
