Bublacustrine Glacial Erosion in Montana: 

 W. M. Davis, Department of Geology and 

 Geography, Harvard University. Clark fork 

 branch-glacier seems to have done its visible 

 erosive work on the valley-side spurs — and 

 presumably a considerable amoimt of invis- 

 ible work on the valley bottom — although it 

 must have been wholly submerged in Lake 

 Missoula for two or three score, if not for four 

 score miles. 



The Effect of Stretching on the Bate of 

 Conduction in the N euro-Muscular Networh in 

 Oassiopea: J. F.McClendon, Department of 

 Physiology, University of Minnesota and Tor- 

 tugas Laboratory, Carnegie Institution of 

 Washington. Appare'ntly stretching the nerve 

 does not change the rate. 



A Criticism of the Evidence for the Muta- 

 tion Theory of De Vries from the Behavior 

 of Species of Oenothera in Crosses and in 

 Selfed Lines: Bradley Moore Davis, Depart- 

 ment of Botany, University of Pennsylvania. 

 Although most of the genetical work on 

 Oenotheras has not been interpreted in Mendel- 

 ian notation, there is clear evidence of order in 

 the results in inbreeding and crossing : the 

 difficulty has been to discover and to isolate 

 simple material in the confusion of mixed 

 and impure forms of these plants. 



The Spectra of Isotopes and the Vibration 

 of Electrons in the Atom: William D. Har- 

 kins and Lester Aronberg, Kent Chemical 

 Laboratory and Ryerson Physical Laboratory, 

 University of Chicago. The spectra of isotopes 

 have previously been reported as identical 

 within the errors of measure. The authors 

 find, however, a slight difference. The wave- 

 length of uranio-lead was very slightly longer 

 than that of the ordinary lead. 



The Effect of Oxygen Tension on the Meta- 

 iolism of Oassiopea: J. F. McClendon, De- 

 partment of Physiology, University of Minne- 

 sota and Tortugas Laboratory, Carnegie Insti- 

 tution of Washington.

RESULTS OF CORN DISEASE INVESTIGATIONS 



A PRELIMINARY Summary of three years' in- 

 vestigations of certain little understood com 

 diseases made in Illinois and Indiana, in- 

 cludes some interesting facts which the writers 

 desire to present at this time. This study has 

 been conducted both in the field and in the 

 laboratory. A more complete statement of the 

 results will be published in the near future.
