Physiology Department Medical School, Johannesburg. March 4, 1955 Dear Rosalind, Thank you very much for your letter: I didn't spend much time in London when I got back but am sorry that I didn't see you again. To business first: I can't find anybody here suitable for the position that you have to offer. All my old students have either gone to England already or are doing Medicine here. Have you tried the Biochemistry Departments at English Universities? I can make one suggestion: a friend of mine, who is a fellow of Christchurch College at Oxford, teaches Biochem. and may know of someone. His name is Dr. A.C. Allison and the address is the college. I am sorry I can't be more helpful. My own work is under way at last. I'm continuing with work begun in Berkeley, namely phage growth in protoplasts. I should be able to tell whether RNA is needed for specific protein synthesis and there may possible [sic] emerge a biological test for RNA. If this is so we could tell whether ppns. were degraded at all. But all this is pure possibility at the moment; however, I shall keep you in touch with any developments. I had a letter from Jack Dremitz who says that he and Alex Rich have taken pictures of TMV and the noninfectious protein and have evidence that the RNA is on the inside. How is your own work getting on? I am so isolated here that I depend on letters to keep me in touch. Yours sincerely, Sydney
