I am working as an information o:ficer for WHO, The job draws on averything I have Studied to date and never ceases to be a source of fascination and stim- ulation to me. At present I am preparing the November issue of World Health, It will be devoted to the problems of human biometeorology. I have just finished reading some works which correlate birth rate, congenital defects and incidence of lunacy to the seasons, I recall that during one of your visist to Wynnewood you regarded such findings with a jaundiced eye, Would you be good snough to drop me a short note with reference material I could consult on the subject. If what work has been done is Siated or incorrect would you be kind enough to let me know your own views on the matter. Unfortunately we work on a limited timetable, and I have to have the final copy in by the 20th of this month, With best personal regards to you and Mrs, Lederberg, soe Lolo ‘A | Claude K
