Eesearcli Laboratory of the General Electric 

 Company, Schenectady, New York. Cross- 

 sections and len^hs are calculated for a va- 

 riety of molecules. Various theoretical con- 

 ditions are developed. 



" The Importance of the Water contained in 

 the Deeper Portions of the Subsoil : " F. J. 

 Alway and G. E. McDole, Minnesota Agricul- 

 tural Experiment Station. The moisture of 

 the deeper subsoil wiU be able to move upward 

 only so slowly and through such a short dis- 

 tance in a single season that it will be at most 

 of no practical benefit to annual crops. 



" The Transformation of Pseudoglobulin 

 into Euglobulin : " William N. Berg, Patholog- 

 ical Division, Bureau of Animal Industry, 

 Washington, D. C. The loss of pseudoglobulin 

 in the heated sera corresponds almost quanti- 

 tatively with the gain of euglobulin in the 

 same sera. 



" A Case of ISTormal Embryonic Atresia of 

 the Esophagus : " H. E. Jordan, Department of 

 Anatomy, University of Virginia. A descrip- 

 tion of the phenomenon for turtles. 



" Studies of Magnitudes in Star Clusters, V. 

 Further Evidence of the Absence of Scatter- 

 ing of Light in Space : " Harlow Shapley, 

 Mount Wilson Solar Observatory, Carnegie 

 Institution of Washington. 



" The History of the Primordial Germ Cells 

 in the Loggerhead Turtle Embryo : " H. E. 

 Jordan, Department of Anatomy, University 

 of Virginia. 



" Studies of Magnitudes in Star Clusters, 

 VI. The Relation of Blue Stars and Variables 

 to Galactic Planes : " Harlow Shapley, Mount 

 Wilson Solar Observatory, Carnegie Institu- 

 tion of Washington. The stellar distribution 

 in the so-called globular clusters has an under- 

 lying elliptical symmetry; therefore not only 

 certain nebulae, our solar system, and the whole 

 galactic system, but even the globular clusters 

 have the oblateness that is general and funda- 

 mental in the dynamics of stellar groups. 



" Zuni Chronology : " Leslie Spier, American 

 Museum of Natural History, New York. It 

 has been found possible to establish a chrono- 

 logical scale with applications to American 

 culture-history. 



" The Age of the Bolivian Andes : " Edward 

 W. Berry, Geological Laboratory, Johns Hop- 

 kins University. There is definite evidence 

 that parts of the high plateau and of the east- 

 ern Cordillera stood at sea level in the late 

 Tertiary. 



" Large Current-Eipples as Indicators of 

 Paleography : " Walter H. Bucher, Department 

 of Geology, University of Cincinnati. A 

 study of the Cincinnati Anticline. 



" The Bearing of Selection Experiments 

 with Drosophila upon the Frequency of Ger- 

 minal Changes : " Edwin Carleton MacDowell, 

 Station for Experimental Evolution, Carnegie 

 Institution of Washington. A study of extra 

 bristles indicating that they are primarily oc- 

 casioned by one germinal unit and that no 

 change of evolutionary or practical signifi- 

 cance has occurred during fifty generations. 



" Pressure Phenomena accompanying the 

 Growth of Crystals : " Stephen Taber, Depart- 

 ment of Geology, University of South Caro- 

 lina. Many phenomena connected with the 

 metamorphism of rocks, the growth of concre- 

 tions, and the formation of mineral deposits 

 are difficult to explain under any other hy- 

 pothesis than that growing crystals have made 

 room for themselves by exerting pressure on 

 the surrounding material. 



" A New Method of Transforming Esters of 

 a-Aminoaeids into their Corresponding Iso- 

 thiocyanates : " Treat B. Johnson and Arthur 

 A. Ticknor, Sheffield Scientific School, Yale 

 University. 



" The Geology of the Fiji Islands : " Wilbur 

 G. Foye, Department of Geology, Middlebury 

 CoUege, Middlebury, Vermont. It can not be 

 said that the modern reefs of Fiji fully sup- 

 port Darwin's theory. 



" Dominance of Linked Factors as a Means 

 of Accounting for Heterosis : " Donald F. 

 Jones, Bussey Institution, Harvard University. 



" Chemically Induced CrowngaUs : " Erwin 

 F. Smith, United States Department of Agri- 

 culture. Small tumors have been produced by 

 the application of various chemicals. 



" Dynamical Systems with Two Degrees of 

 Freedom : " George D. Birkhofi, Department 

 of Mathematics, Harvard University.
