June 29, 2021 Dear Don, a) Thank you for your reply. b) I defer to your judgment about the importance that Dr. Busch might have attached to potential sales of his book. c) I would make no objections if Dr. Busch assigned to you his rights to the German and English texts that I have provided to him. d) I am still waiting for his reply. e) I wish you a comfortable and healthy summer. Jochen
