FECOOOOOOIOCERX. SORORURUOOCEE Dept. Medical Genetics Dear Dr. Demerec: Thank you so much for the pictures; it was very generous of you to lend us your camera, AS a matter of fact, it is lucky ours was dropped. There was something wring with the shutter even before then, and we had mch better pictures after it was repaired. foam sorry that I confused your roll with one of ours. iie are sending you your pictures now (except one we want to copy ourselves) ani will send another set of copies of some of ours we thought you'd be interested in. With best regards, bal an “Joshua Lederberg
