August 14 Dear Mr. Lederberg: Under separate cover, I send you a reprint of my paper issued in Revue Canadienne de Biologie. The reprint of the paper dealing with phage growth on irradiated bacteria are still in France. If I go back to my country by the end of next month, I shall send you one of them from over there. Perhaps would you be interested in another paper by myself and R. Wahl, issued in [ . . . ] de l'Institut Pausteur 1845 entitled "Precision sur l'action des zayoux ultraviolet sur les bacteriophages". I would be glad to get in contact with Dr. Tatum and you, and to receive in France news of your work. My address is Institut du Radium 26 rue d'ULM Paris (5) France With best regards to Dr. Tatum, and to you Sincerely yours Raymond Latarjet M.D., Ph.D.
