 fornia, will speak upon ' ' The Work of 

 a Modern Observatory. ' ' 



Sessions in physics will be provided

 of spectroscopic investigations of the 

 physics of the air and of high potential 

 electrical experimentation. 



The program of the Geological So- 

 ciety of America will include at least 

 three topics — erosion and deposition in 

 arid climates, diastrophism on the Pa- 

 cific coast and petrologieal problems of 

 the Pacific area. 



Meetings of the Paleontological So- 

 ciety will provide at the first session a 

 series of four addresses upon the gen- 

 eral criteria of correlation. In three 

 following sessions symposia will be held 

 for a comparison of the Triassic, Cre- 

 taceous and Miocene faunas of the 

 Pacific coast with those of similar 

 periods in other parts of the world. 



The program for zoology will include 

 sessions for the discussion of general 

 problems of zoology, embryology and 

 development, problems of conservation, 

 the role of variation and heredity in 

 evolution, recent contribiitions from the 

 field of protozoology, and questions of 

 geographic distribution and of marine 

 biology. 



The botanical sessions will be de- 

 voted to problems centering upon gym- 

 nosperms, which as a group are so 

 w'idely distrilmted over the Pacific 

 coast; upon the relation of plants to 

 light; the geographic distribution of 

 plants with especial reference to the 

 origin of the California flora, and upon 

 marine and freshwater algse. 



Sessions for psychology will prob- 

 alily consider problems of animal psy- 

 chology, the testing of mental traits 

 and the application of psychology to 

 law and medicine. 



Tlie anthropological sessions have been

Sessions for political and social sci- 

 ence are being planned in support of 

 meetings of several societies organized 

 in these fields which will meet during 

 the week immediately following the 

 convocation week of the American As- 

 siiciation. 



The sessions for education will be de- 

 voted to the scientific study of selected 

 educational problems. 



Sessions for agriculture will provide 

 for the discussion of problems of ani- 

 mal husbandry, nutrition and food 

 analysis, agronomy and farm man- 

 agement, soil analysis, agricultural 

 chemistry and fertilizers and horticul- 

 ture. 



Among other organizations which will 

 hold special meetings during the con- 

 vocation week of the American Associa- 

 tion are the Archeological Institute of 

 America, the American Phytopatholog- 

 ieal Society, the American Genetic So- 

 ciety, and an Entomological Congress 

 under the auspices of several entomo- 

 logical societies. Meetings of several 

 societies devoted to economics and so- 

 cial and political science will occur 

 during the week immediately follow- 

 ing. The Association of American 

 Agricultural Colleges and Experiment 

 Stations and several other agricul- 

 tural societies have also appointed

 gust. The later part of the month will
