5. The Processes taking Place in the Body 

 by which the Number of Erythrocytes per 

 Unit Volume of Blood is increased in acute 

 Experimental Polycythemia: Paul D. Lam- 

 son, Pharmacological Laboratory, Johns 

 Hopkins University. 



It is concluded that the liver acts as a 

 reservoir for erythrocytes. The process by 

 which the liver increases the number of the 

 erythrocytes is thought to be a loss of plasma 

 from the liver capillaries together with a con- 

 striction of these vessels driving the erythro- 

 cytes on into the blood stream. 



6. The Influence of Morphin upon the Elim- 

 ination of Intravenously Injected Dextrose 

 in Dogs: I. S. Kleiner and S. J. Meltzer, 

 Department of Physiology and Pharmacol- 

 ogy, Rockefeller Institute for Medical Re- 

 search. 



Morphin increases the elimination through 

 the kidneys of intravenously injected dextrose 

 and retards the return of the sugar content 

 of the blood to its previous level. 



7. The Work of the American Meteor Society 

 in 191k and 1915 : Charles P. Olivier, Lean- 

 der McCormick Observatory, University of 

 Virginia. 



Prom the 5,543 observation of meters, 139 

 radiants have been deduced with sufficient ac- 

 curacy to calculate parabolic orbits for the 

 meteor streams they represent. 



8. The Light Excitation by Slow Positive and 

 Neutral Particles: A. J. Dempster, Ryer- 

 son Physical Laboratory, University of Chi- 

 cago. 



Very slow positive rates are still able to ex- 

 cite light with a speed corresponding to less 

 than 5 volts. The neutral rays can also ex- 

 cite light at very slow speeds; the excitation 

 may occur directly because of the collision of 

 a neutral particle with a neutral molecule 

 of the gas. 



9. An Apparent Dependence of the Apex and 

 Velocity of Solar Motion, as determined 

 from Radial Velocities, upon Proper Mo- 

 tion: C. D. Perrine, Observatorio Nacional, 

 Argentino, Cordoba. 



The position of the solar apex and the solar 

 velocity appear to vary with the proper motion 



of the stars used in the determination. Such 

 variations point ultimately to some form of 

 rotary or spiral motion among the stars. 



10. Channeled Grating Spectra, obtained in 

 Successive Diffractions: C. Barus, Depart- 

 ment of Physics, Brown University. 



A brief abstract of work presented by the 

 author to the Carnegie Institution of Wash- 

 ington. 



11. The Effect of Parental Alcoholism {and 

 Certain other Drug Intoxications) upon the 

 Progeny in the Domestic Fowl: Raymond 

 Pearl, Biological Laboratory, Maine Agri- 

 cultural Experiment Station. 



Out of 12 different characters for which we 

 have exact quantitative data, the offspring of 

 treated parents taken as a group are superior 

 to offspring of untreated parents in 8 charac- 

 ters. The results with poultry are in apparent 

 contradiction to the results of Stockard and 

 others with mammals, but the contradiction 

 is probably only apparent. 



12. The Effectors of Sea- Anemones: G. H. 

 Parker, Zoological Laboratory of the Mu- 

 seum of Comparative Zoology at Harvard 

 College. 



It seems clear that among the muscles in 

 sea-anemones there are not only independent 

 effectors, and tonus muscles associated with 

 nerve-nets, but neuromuscular combinations 

 that exhibit true reflex action. 



13. Preliminary Evidence of Internal Motion 

 in the Spiral Nebula Messier 101 : A. van 

 Maanen, Mount Wilson Solar Observatory, 

 Carnegie Institution of Washington. 



The mean rotational motion is 0.022" left- 

 handed; the mean radial motion is 0.007" out- 

 ward. There is perhaps a small decrease of 

 the rotational motion with increasing distance 

 from the center. The annual rotational com- 

 ponent of 0.022" at the mean distance from the 

 center of 5' corresponds to a rotational period 

 of 85,000 years. 



14. Symposium on the Exploration of the 

 Pacific — 



(a) The Exploration of the Pacific: W. M. 

 Davis, Department of Geology and Geogra- 

 phy, Harvard University.
