PUBLISHED : The “1515 MASSACHUSETTS AVENUE, N. W. TELEPHONE: ADAMS 4.7111 CABLE ADDRESS: ADVANCESCI the NEWSWEEKLY for scientists BY THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF MONTHLY WASHINGTON 5, OD. C, the LITERARY magazine July 1, 1953 Dr. Joshua Lederberg Department of Genetics University of Wisconsin Madison, Wisconsin Dear Josh: I happened to see the article on "Sex in Bacteria: Genetic Studies, 1945 - 1952," which you have contributed to the symo- sium volume to be published by the AAAS. It is exactly the sort of thing we need and like to have as a lead article in SCIENCE. If you have no objection, I would like to use your article in that way’ in the very near future--probably before the end of July. You wouldn't object to a prepublication of your article in this way, would you? On previous occasions SCIENCS has used chapters from forthcoming books or articles to be published in symposia in this way. I am also writing to Dr. Wenrich to get his permission. = aL With best persona Bentley Gla Acting Chaifryran Editorial Board Pa BG/chd cC: Dr. E. L. Tatum of SCIENCE science
