Pusptic HEALTH LABORATORY SERVICE (Directed by the Medical Research Council for the Ministry of Health) Municipal Buildings, 14.3, Regent Road, Salford, 5. TRAfford Park 34.12 énd. April 1953. Dear Professor Lederberg, Thank you for your letter making formal offer of an assistanship in your department. I enclose a formal acceptance. I had already made preliminary enquiries of the local U.S. Consul. He informed me that one of the visa requirements would be a formal statement of dollar support, including accomodation and compensation, for the duration of my stay. I will find out whether your letter is sufficient for this purpose or whether some further certification is required. I believe it might be possible to obtain an allocation of dollars to cover my first months. I will make enquiries, through my bankers, from the Treasury. I will let you know in due course of my travel arrangements. It is probable that I will break my journey to visit some relatives in Connecticut. I have made application to the U.S. Educational Commission in the U.K. for the grant of a Fulbright Travel Allowance. Thank you for your offers of assistance. Yours sincerely, -” pole Prof. J. Lederberg, Department of Genetics, University of Wisconsin, Madison, 6. Wisconsin, U.S.A.
