Dear Wendell:
I'm sorry that I did not have an opportunity to attend any of the sessions of the Stein Symposium so that we could get together.  The revisions of your paper certainly seem satisfactory to me and I feel as you do that Roy Avery's suggestion should probably be honored out of deference to him.
Sincerely yours,
Maclyn McCarty, M. D.
