and the wave-lengths have been accurately 

 determined. The results also indicate that 

 the relationship holds for very much softer 

 X-rays than those of ordinary penetrating 

 power. 



2. Further Evidence as to the Relation be- 

 tween Crown Gall and Cancer: Erwin F. 

 Smith, Laboratory of Plant Pathology, 

 United States Department of Agriculture. 

 There are discussed: Fundamental concepts, 



human and animal tumors for which no cause 

 has been discovered, earlier discoveries in 

 plants, further discoveries, other resemblances 

 of crown gall to cancer in man and animals, 

 possibility of the existence of carcinomas and 

 of mixed tumors in plants, production of em- 

 bryonal teratomata, and bearing of these dis- 

 coveries on the cancer problem. 



3. Locomotion of Sea-Anemones: G. H. 

 Parker, Zoological Laboratory of the Mu- 

 seum of Comparative Zoology at Harvard 

 College. 



The pedal portion of a sea-anemone, like its 

 tentacles, must contain a neuromuscular mech- 

 anism sufficient for the activity of that part 

 of its body. 



4. The Behavior of 8 ea- Anemones : G. H. 

 Parker, Zoological Laboratory of the Mu- 

 seum of Comparative Zoology at Harvard 

 College. 



Sea-anemones are animals whose momentary 

 conditions are dependent upon the combined 

 stimuli of their immediate surroundings 

 rather than forms that are greatly influenced 

 by their past history, and their unity is not of 

 a pronounced type; they are more in the 

 nature of a sum of parts than they are organic 

 units of the type of most of the higher animals. 



5. A Contribution to the Petrography of 

 Japan: J. P. Iddings and E. W. Morley, 

 Brinklow, Maryland, and West Hartford, 

 Connecticut. 



Seventeen detailed chemical analyses are 

 given of Japanese lavas. 



6. Is There a Temperature Coefficient for the 

 Duration of Life? Jacques Loeb and J. H. 

 ISTorthrup, Eockefeller Institute for Med- 

 ical Research, New York. 



In three series of experiments on the fruit 

 fly Drosophila, it is found that the duration 

 of life in the cases examined has a tempera- 

 ture coefficient of the order of magnitude 

 which is characteristic for life phenomena and 

 chemical reactions in general. 



I. On the Suggested Mutual Repulsion of 

 Fraunhofer Lines: Charles E. St. John, 

 Mount Wilson Solar Observatory, Carnegie 

 Institution of Washington. 



The author is unable to find evidence of the 

 mutual repulsion suggested and in so far as 

 mutual influence is a necessary corollary of 

 anomalous dispersion in the sun, evidence of 

 this also is lacking. 



8. An Attempt to detect the Mutual Influence 

 of Neighboring Lines in Electric Furnace 

 Spectra showing Anomalous Dispersion: 

 Arthur S. King, Mount Wilson Solar Ob- 

 servatory, Carnegie Institution of . Wash- 

 ington. 



Although the material in the investigation 

 is limited by the scarcity of suitable pairs of 

 lines, the lines actually tested have shown no 

 tendency toward a repulsion. 



9. Synthesis of the Base CJLfiN„ derived from 

 M ethyl- Aminomethyl-S, 4-Dihydroxyphenyl- 

 carbinol: Chas. A. Eouiller, Pharmacolog- 

 ical Laboratory, The Johns Hopkins "Uni- 

 versity. 



A continuation of some work by Abel with 

 a suggestion as to a relation to work by 

 Curtius. 



10. Extinguished and Resurgent Coral Reefs: 

 W. M. Davis, Department of Geology and 

 Geography, Harvard University. 



II. The Origin of Certain Fiji Atolls: W. M. 

 Davis, Department of Geology and Geog- 

 raphy, Harvard University. 



The two papers offer a discussion of obser- 

 vations made during the author's Shaler 

 Memorial voyage across the Pacific. 

 12. Interferometer Methods based on the 



Cleavage of a Diffracted Ray: C. Barus, 



Department of Physics, Brown University. 



The prismatic method of cleaving the inci- 

 dent beam of white light is available for the 

 superposition of non-reversed spectra, under
