I'm very sorry not to have been able to visit you again but I got involved in work in Berkeley. As you can see, I'm
on the point of departing for Europe and I will go and see Bruce Stocker in London and give him your regards.
I was wondering whether you could put me on your reprint mailing list (if you have such a thing) as one is so isolated in
S. Africa. Incidentally I would very much like a reprint of your PNAS paper this year. My address is:
Department of Physiology,
University of the Witwatersrand
I hope that you won't mind if I write to you at odd times seeking advice.
