has fulfilled his share of the work. It must 

 be confessed, however, that one misses in 

 every chapter, almost on every page, a refer- 

 ence to the work which has been done on 

 similar lines by the famous teachers and lec- 

 turers of England and America. It is doubt- 

 less true that the apparatus described in this 

 book is that most generally available for Ger- 

 man teachers; but in countless cases various 

 improvements made by lecturers of other 

 countries would be of great advantage in the 

 teaching of physics in German institutions. 



Muller-Pouillet, Lehrhuch der Physik. Edited 



by Leopold Pfaundler. Tenth edition. 



Volume I. Vieweg, Brunswick. 1905. 



In this tenth edition of this well-known 

 standard book on physics, the editor has re- 

 ceived the cooperation, in various chapters, of 

 Lummer, Wassmuth, Perntner, Drueker, 

 Kaufmann and Nippoldt, and undoubtedly the 

 entire work when it is published will be much 

 more complete than in the past. In the vol- 

 ume before us, which is devoted to ' Mechanics 

 and Acoustics,' the number of pages and num- 

 ber of illustrations are less than in the pre- 

 vious edition; but the size of the pages has 

 been enlarged, and the illustrations are all 

 that could be desired. The book is designed 

 not specially for students of physics, but for 

 students of natural history, medicine and 

 pharmacy as well, and also for use by makers 

 and designers of physical apparatus. It f ulfi.ls 

 its purpose admirably, giving many interest- 

 ing details in regard to the construction of the 

 apparatus and the theory of the experiments. 



In this first volume it is impossible to give 

 unlimited praise, owing to the almost complete 

 absence of reference to the work of English 

 students, and also to the fact that so few 

 references are given to recent work. To a 

 student who wishes to become acquainted with 

 the main phenomena of physics, and who is 

 not specially interested in the most recent 

 theories, this volume will prove most valuable. 

 The former edition of this treatise on physics 

 has long filled a place of its own in all li- 

 braries, and it is undoubtedly true that the 

 present edition will be even more acceptable.

SCIENTIFIC JOURNALS AND ARTICLES. 



The May number of the Journal of Nervous 

 and Mental Disease opens with a study of 

 cerebellar tumors and their treatment by 

 Drs. J. J. Putnam and G. A. Waterman. A 

 number of operations for the relief of such 

 tumors are reported, in three of which the 

 results were decidedly satisfactory. Dr. E. 

 B. Angell contributes a paper on hypesthesia 

 and hypalgesia and their significance in func- 

 tional nervous disturbances, and under the 

 title, ' The Coming of Psychasthenia ' Dr. 

 Blumer discusses the importance of nomen- 

 clature in nervous and mental disease and 

 advocates the adoption of Janet's ' Psychas- 

 thenia.' 



The first attempt to list and classify the 

 Diptera of Minnesota has been made this year 

 in the shape of the Annual Eeport of the 

 Minnesota State Entomologist. The report is 

 illustrated with drawings of various species of 

 flies and two excellent colored plates. Since 

 this work has come from the press seventy-five 

 additional species have been collected within 

 the boundaries of the state. These have been 

 named and listed, and sent to entomologists 

 and others likely to be interested. Any one 

 who has not already received the report and 

 the appendix who desires them can obtain the 

 same by writing to Mr.- F. L. Washburn, State 

 Experiment Station, St. Anthony Park, Minn. 

 Cloth-bound report requires eight cents for 

 postage, paper-bound copies sis cents. 



The Gebriider Borntrager, of Halle, an- 

 nounce the publication of a Zeitschrift fur 

 Gletcherhunde, which is to be the organ of 

 International Glacier Commission and will 

 be edited by Professor Edouard Briickner, of 

 the University of Halle. The journal will 

 appear at irregular intervals, the subscription 

 price being sixteen Marks for a volume of 

 five numbers. 



SOCIETIES AND ACADEMIES. 



THE TORREY BOTANICAL CLUB. 



The club met on April 25 in the museum 

 building at the New York Botanical Garden. 

 President Eusby presided and there was an 

 attendance of sixteen.
