Letter to someone interested in his work, in part: "I wish to thank you for your kind letter and remarks about my work and I am delighted to be able to comply with your request for my autograph. As you are obviously interested in my activities, I am placing your name on my Mailing List and enclose a copy of my latest Bulletin. I am well aware that without the moral and financial support of my friends I would find it much more difficult to continue."
