THE JOHNS HOPKINS SCHOOL OF MEDICINE BALTIMDO NOV . ) 1962 DEPARTMENT OF PHYSIOLOGICAL GHEMISTRY 725 N. WOLFE STREET November 13, 1962 Dear Josh: It was good to see you in your native habitat last week, but I still wish we had a little more time to talk membranes. However, I had a good chat with Dr. Shneour. He has a very interesting idea on protection against oxygen which fits in very well with some of our own ob- servations. I hope we can discuss this further another time. By rights, I should not go traveling anymore for some time, but if I do come out in January for that Cell Organization meeting, I hope I may stop in to see you before or after. Enclosed is a check for your expenses on the Herter Lectures. A3 bu Lu Vf oF With best greetings, Sincerely yours, ca LR Ef: Le A Albert L.
