UNIVERSITY OF LONDON POSTGRADUATE MEDICAL SCHOOL OF LONDON Telegrams POSGRADMED CHISK LONDON DUCANE ROAD Telephone LONDON, W.12 SHEpherds Bush 1260 (4 lines) 6 July,1952. Dear Cavalli, Here is an abstract of my anticipated Pallanza paper. It is exactly 60 lines! I hope you will be presenting your views on this controversial subject. I forgot to say in my recent letter that if I can do anything for you in the way of correcting proofs of your JGM paper I will be only too happy. I expect,though,that you would like this done by someone more “up" in genetics. But let me know if I can help. With best wishes, wet?
