UNIVERSITY OF CAMBRHDGE Arthur J. R&ker, Esq,, c/o Eric J. Wells, 64. Browning Avenue, Boscombe, Bournemoath. Dear Mr. Walker, Thank you for your letter, Iwisht qourwork could be used to make people feel better an 83 etter, but it will be many years before we are likely to bz able to do this. I very much doubt if these a simple effect of environment on character, apart from the well-known effects ,hf a hot climate. In any case I think that research on the ;ligher nervous system Is more likely to lead to scientl.f!c: insight into mm's behaviour than our work will. Thanking you for your good wishes, Yours sincerely, l?. H. C, Crick
