indicate that the carbon- 14 activity of ground or surface water can be 

 readily determined and that this metliod can be used to determine 

 several of the hydrologic characteristics of water-producing strata. 

 Instrmnentation for this research has been completed and includes: 

 (1) apparatus for extracting the bicarbonate and dissolved carbon 

 dioxide from the water samples and (2) a system to convert the carbon 

 dioxide to pure methane gas.

OTHER activities 



The division was represented during the year at a number of scien- 

 tific meetings. At the American Institute of Biological Sciences 

 meeting in August at Oregon State University, Corvallis, Oreg., were 

 W. Shropshire, L. Price, M. M. Margulies, R. L. Latterell, and W. H. 

 Klein. Papers presented at the meetings included "The Effect of 

 Light and Chloramphenicol on Development of Photosynthetic Ac- 

 tivities of Leaves," by M. M. Margulies; "Responses of Phy corny ces 

 to High Intensity Light," by W. Shropshire; and "Some Responses 

 of the Bean Hypocotyl," by W. H. Klein. Dr. Klein attended the 

 executive committee sessions of the American Society of Plant 

 Physiologists. 



Dr. D. L. Correll traveled to Woods Hole Oceanographic Institu- 

 tion, Yale University, and the Haskins Laboratories to confer on as- 

 pects of marine biology research. In August Dr. Klein with a repre- 

 sentative of the U.S. Atomic Energy Commission visited the Univer- 

 sity of Washington at Seattle. J. H. Harrison attended the Inter- 

 mediate Seminar for Scientific Glass Blowers held at the State Uni- 

 versity of New York in Alfred in September. In November, J. J. 

 Sigalove and Dr. W. H. Klein went to Delaware, Ohio, to consult with 

 Dr. J. G. Ogden of the carbon-dating laboratory at Ohio Wesleyan 

 University. In January Dr. D. L. Correll and L. Lott made a col- 

 lecting trip to the Florida Keys for specimens of marine algae.
