then as chief. During this period the survey- 

 has grown rapidly. In order that the bureau 

 may continue to have the benefit of Mr. Hen- 

 shaw's knowledge and experience he will retain 

 official connection with it as consulting biol- 

 ogist. Mr. E. W. Nelson, who has been on 

 the scientific staff of the bureau since 1890 and 

 assistant chief since 1914, has been appointed 

 to succeed Mr. Henshaw as chief of the 

 bureau. 



As has been already noted in Science, meet- 

 ings of the Geological Society of America and 

 the American Paleontologieal Society will be 

 held in the Education Building, Albany, on 

 December 27, 28 and 29. The address of the 

 president of the Geological Society, Dr. John 

 M. Clarke, is on " The Philosophy of Geology 

 and the Order of Eesearch." That of the 

 president of the Paleontologieal Society, Dr. 

 Eudolf Euedemann, is on " Persistent Paleon- 

 tologieal Types." There will be public ad- 

 dresses by Dr. George Otis Smith, director of 

 the TJ. S. Geological Survey, on " Geology and 

 Public Service," and by Professor Eichard S. 

 Lull, of Yale University, on " The Pulse of 

 Life." There will be symposia on " The Geol- 

 ogy of Petroleum " and on " The Interpreta- 

 tion of Sedimentary Bocks." 



The Section of Agriculture of the American 

 Association for the Advancement of Science 

 will hold its session on the afternoon of 

 December 27, at 2 o'clock, in the Brincker- 

 hoff Theater, Barnard College, Columbia 

 University. At this session the address 

 of the retiring vice-president of the sec- 

 tion, Dean Eugene Davenport, of the Uni- 

 versity of Elinois, will be delivered on the 

 subject of " The Outlook for Agriculture." 

 The subject will be further considered in a 

 symposium on the general topic of " The 

 Adjustment of Science to Practise in Agricul- 

 ture." This will be presented under the fol- 

 lowing four heads: (1) Some Factors lying 

 between Scientific Eesults and the Farm, by 

 Dr. H. J. Wheeler, of Boston ; (2) Limitations 

 of Science to Progress in Agriculture, by Dr. 

 J. G. Lipman, director of the New Jersey Ex- 

 periment Stations; (3) Economic Factors as 

 affecting the Applications of Science, by Dr. 



G. F. Warren, of the College of Agriculture 

 at Cornell University; and (4) Begional con- 

 ditions as determining the Type of Agricul- 

 tural Inquiry, by Director B. Youngblood, of 

 the Texas Experiment Station. The divisions 

 of the subject will be treated in a semi- 

 popular manner, rather than in their strictly 

 technical aspects, and the discussion will not 

 be restricted to any particular department of 

 agricultural science. The purpose is to make 

 the program one of general interest. There 

 will be opportunity for free discussion. 



Through the courtesy of the American Mu- 

 seum of Natural History and in connection 

 with the convocation week meetings (Decem- 

 ber 26-30) of the American Association for 

 the Advancement of Science, the New York 

 sections of the American Chemical Society, 

 chairman, Dr. J. Merritt Matthews; The 

 American Electrochemical Society, chairman, 

 Dr. G. Colin Fink; The Society of Chemical 

 Industry, chairman, Dr. Jerome Alexander; 

 and The Museums of the Peaceful Arts, acting 

 president, Dr. George F. Kunz, are planning 

 an exhibition on preparedness, to be shown on 

 the fourth floor of the museum building. The 

 exhibit will consist of a set of the native ele- 

 ments belonging to the American Museum of 

 Natural History ; a collection of all the known 

 elements; electrochemical products, nitrogen 

 products from the air; coal-tar derivatives; 

 and explosives — the new chemistry of pre- 

 paredness developed during the past two years. 

 The exhibit will be shown during the convoca- 

 tion week and for one month thereafter to the 

 public. Dr. George F. Kunz is chairman of 

 the exhibition committee. Scientific research 

 will be shown in a special exhibit dealing with 

 the life and work of Pasteur. Letters, manu- 

 scripts, pictures or other memorabilia which 

 might be of interest in this connection are 

 greatly desired for this purpose. Any one 

 having material that would add to the Pasteur 

 exhibit is requested to communicate with Pro- 

 fessor C.-E. A. Winslow, curator of public 

 health, American Museum of Natural History, 

 77th Street and Central Park West, New York 

 City, who is chairman of this special branch 

 of the committee.
