occurs this year at tlie University of Min- 

 nesota in Minneapolis. The scientific pro- 

 gram covers the three days of December 27, 

 28 and 29. The Local Committee is planning 

 attractive features of general interest, includ- 

 ing a trip to Rochester, that center of medical 

 and surgical activities which the war condi- 

 tions have raised to a plane of paramount 

 importance. The four societies of the federa- 

 tion are the American Physiological Society, 

 the American Society of Biological Chemists, 

 the American Society for Pharmacology and 

 Experimental Therapeutics, and the American 

 Society for Experimental Pathology. Many 

 members of these societies are engaged in 

 scientific work in support of our government 

 in the great war struggle. The general secre- 

 tary hopes that the scientific program will 

 strongly reflect this present activity and that 

 the meeting will be one of ujiusual interest 

 and enthusiasm. The members of the socie- 

 ties are urged to make vigorous efforts to at- 

 tend and to contribute to the program. The 

 fact that the meetings of the American Asso- 

 ciation of Anatomists and the American Zo- 

 ological Society occur at the same time and. 

 place lends the strong appeal of mutual and 

 cooperative interest which every member o£ 

 the federation will find it difficult to resist.

THE PITTSBURGH MEETING OF THE AMERICAN 

 SOCIETY OF NATURALISTS 



The American Society of ISTaturalists, in 

 affiliation with Section P of the American As- 

 sociation for the Advancement of Science and 

 the Botanical Society of America, will hold its 

 thirty-fifth annual meeting at Pittsburgh, 

 under the auspices of the University of Pitts- 

 burgh, beginning Tuesday, January 1, 1918. 



There will be a smoker for Biologists on Sat- 

 urday evening, December 29. 



The Botanical Society of America will place 

 the genetical papers of its program on Mon- 

 day morning, December 31, and in the after- 

 noon of the same day will present an invitation 

 program including the presidential address of 

 E. A. Harper. 



Section F of the American Association for 

 the Advancement of Science will have on Mon- 

 day morning the address of the retiring vice- 

 president, G. H. Parker, and in the afternoon 

 a symposium on " The contributions of zoology 

 to human welfare." 



By this arrangement there will be sessions 

 of interest to the members of the American 

 Society of Naturalists on the day preceding 

 the meetings of the society. 



The American Society of Naturalists will 

 offer for Tuesday morning, January 1, a pro- 

 gram of invitation papers. 



The program for Tuesday afternoon will be 

 a symposium on " Factors of organic evolu.- 

 tion." 



The Naturalists' dinner, in which members' 

 of the affiliated societies are invited to partici- 

 pate, will be held on the evening of Tuesday. 

 At the close of the dinner George H. Shull will 

 give his presidential address, " The genotype 

 and its environment." 



As the result of an apparently growing de- 

 sire on the part of members of the American 

 Society of Naturalists to contribute papers, 

 the Program Committee will this year receive 

 titles for a program to begin on Wednesday 

 morning, January 2. It is desired that the 

 papers be short and it should be remembered 

 that the interests of the Naturalists are pri- 

 marily on problems of organic evolution. The 

 papers on this program will in general be ar- 

 ranged in order of the receipt of the titles, ex- 

 cept that papers on similar subjects may be 

 grouped. Titles with estimated length of de- 

 livery and statement of lantern or chart re- 

 quirements must be in the hands of the secre- 

 tary by December 1. 



Nominations for membership must be sent 

 to the Secretary not later than December 1 in 

 order that the Executive Committee may give 

 them due consideration before the meeting. 

 Blank forms for nominations may be obtained 

 from the secretary. 



Headquarters of the Naturalists will be at 

 the Monongahela House, Smithfield and "Water 

 Streets. Members are advised to make early 

 reservations.
