318 Scientific Intelligence. 



which it coramences and the Society under whose auspices it is 

 published. It is to be hoped that the undertaking may not only 

 receive all needed financial support, but also that editors and 

 authors may inform themselves minutely as to the details of the 

 plan, so that they may prepare subject-indexes for all papers at 

 the time of their publication, thus diminishing very largely the 

 subsequent labors of the collaborators. 



2. British Association. — The annual meeting of the British Asso- 

 ciation for the Advancement of Science was held at Belfast dur- 

 ing the week beginning September 10th. The meeting is de- 

 scribed as having been very successful, about equal in numbers 

 to that held in the same place in 1874, when the attendance was 

 1,951. The address of the President, Professor James Dewar, 

 was of the highest interest (see Nature of Sept. 11), dealing, in 

 addition to some general topics, with the subject of low tempera- 

 ture and the liquefaction of gases, to which he has personally 

 contributed so much. We quote at length from the address in 

 another place. 



3. Experiments in Aerodynamics y' by S. P. Langley. Second 

 edition, pp. 115 with ix plates. Washington, 1902. (Smith- 

 sonian Contributions to Knowledge, No. 801.) — This volume is 

 essentially a reproduction of the first edition of this interesting 

 memoir, which was issued in 1901 and noticed in this Journal in 

 November of that year (vol. xlii, p. 427). Since its first publi- 

 cation, machines made on the principles here described have 

 actually flown, which fact gives a practical interest to the sub- 

 ject ; a description of the heavy steel flying machines is promised 

 for some time in the future. 



4. Elementary Physical Geography ; by William Morris 

 Davis. Pp. x, 401, with numerous maps and illustrations (Ginn 

 and Company.) — It is a pleasure to note the publication of a 

 text-book which presents a subject in an interesting elementary 

 form without the loss of scientific accuracy and a rational mode 

 of treatment. Professor Davis's new text reduced from his 

 *' Physical Geography" is just such a book. 



5. The International Quarterly. — The International Monthly, 

 which since January, 1900 has had a highly successful career 

 under the editorship of Mr. Frederick A. Richardson (Burling- 

 ton, Vt.), will hereafter be continued as a quarterly with the 

 same editorial direction. Each number will be more than double 

 the size of the monthly, and will present articles of live interest 

 by able writers at home and abroad. The September issue (pp. 

 1-214) of The International Quarterly begins vol. vi, of the 

 series.
