According to the By-Lav?s adopted by the 

 Section there vcill be two meetings per year — 

 one in May and the other in December. These 

 meetings are to be held in or near San Fran- 

 cisco. The first Section of the American 

 Mathematical Society, known as the Chicago 

 Section, was organized in 1897 and also holds 

 two meetings per year. The Society holds four 

 meeting per year at Columbia University in 

 addition to a summer meeting, which has gen- 

 erally been held in connection with the meet- 

 ings of the American Association for the Ad- 

 vancement of Science. G. A. Miller,

The 328th meeting was held March 11. A 

 presentation of easts of the Neanderthal, Spy 

 and Engis skulls was made by President W. 

 H. Holmes and Dr. Frank Baker. 



Professor Holmes placed the geologic time 

 scale on the blackboard and located on it 

 the various finds of fossil human remains, ex- 

 plaining the conditions under which the finds 

 were made and the difficulties attending even 

 approximate accuracy in determining their 

 position. 



From the somatological point of view Dr. 

 Baker discussed the criteria of the determin- 

 ation of skulls and applied these to the crania 

 under discussion. Dr. Baker said that the 

 Neanderthal and Spy skulls are certainly not 

 pathological as has been affirmed by some 

 writers. Mr. J. D. McGuire in discussing the 

 paper held that the man of Spy was possessed 

 of classes of artifacts belonging to a much 

 later period than students had generally ad- 

 mitted. 



Dr. A. E. Jenks read a paper entitled ' Some 

 Steps in Amerindian Economics.' This paper 

 defined economic man as one who produces for 

 use and future gain and affirmed that the 

 American Indian north of Mexico had arrived 

 at economic emancipation. Dr. Jenks out- 

 lined the study of economics in this field, giv- 

 ing the ramifications growing out of produc- 

 tion for future gain and the efl^ects on the de- 

 velopment of the Americap Indian. The paper 

 was heard with great interest and provoked an 

 extended discussion participated in by Dr. J. 

 AValter Fewkes, J. D. McGuire, Professor W. 

 H. Holmes and Walter Hough. 



The 329th meeting was held March 25, and 

 was devoted mainly to technologic subjects. 



Mr. Emil Berliner gave an interesting talk 

 on the history of instruments for recording 

 and repeating sounds, tracing the inventions 

 from the eighteenth century to the present. 

 The earliest form of phonograph with tinfoil 

 sheets on which records of speech were made 

 and gramaphone of the most recent type were 

 exhibited and contrasted. 



Mr. Fred. M. Tryon read a paper dealing 

 with the development in hydrotechnies tracing 

 the historic and ethnographic range of the in-
