ACKNOWLEDGEMENTS 



The National Science Board owes a debt of gratitude 

 to a large number of people for their assistance in the 

 preparation of this report. The Board expresses its appre- 

 ciation to all of them for a job well done. 



Valuable aid was provided by the consultants who 

 gave freely of their opinions and served as a general 

 sounding board regarding the handling of the final format 

 of this report, as well as its companion volume, Environ- 

 mental Science: Challenge for the Seventies. This group 

 included: Dr. Julian R. Goldsmith (former member of the 

 National Science Board), University of Chicago; Dr. Louis 

 J. Battan, University of Arizona; Dr. John E. Cantlon, 

 Michigan State University; Dr. Wilbert M. Chapman 

 (deceased), Ralston Purina Company; Dr. Roger Revelle, 

 Harvard University; and Dr. Gilbert F. White, University 

 of Colorado. 



The major responsibility for preparation of this re- 

 port was undertaken by the Staff of the National Science 

 Foundation, working in consultation with the Board and 

 the consultants. Dr. Lawton M. Hartman, III and Dr. 

 Eugene W. Bierly directed the effort. The result is 

 unique: a profile of a section of science that is rich in 

 information, broad in scope, and explicit as to the present 

 status of understanding. The National Science Board 

 expresses its sincere appreciation for the dedicated work 

 of these men. 



The report has been edited by Mrs. Patricia W. Blair, 

 special editorial consultant to the Board. The Board 

 recognizes that her conscientious effort to present each 

 contribution in its best light has made the report much 

 more valuable.

 others have contributed in various ways, and the Board 

 acknowledges the time and effort that these people gave
