Z Lowes 1956 Aug 28th. Dear Dr. Lederberg, It seems a very long time since I last wrote to you from England, but at long last I should like very much to take up your offer of visiting you and your laboratory. I hope that this letter reaches you before you leave for Japan. If indeed I am right in assuming your intention to attend the meetings there. In any case I do not anticipate in [ . . . ] before around 23rd October, which I hope will find you there in any event. Could you let me know if this date is convenient, or any other around about this time. Yours Sincerely, Royston C. Clowes
