I will let you know what I discover. In the meantime, I have taken the opportunity of sending you a copy of an address entitled Doctors and Patients which I delivered last year, in which I refer to the matter on pages 16, 17 and 18. I am also including a report of an address I gave a long time ago when I opened the Oregon Regional Primate Center, the first of the many which now exist in the United States. With kind regards, Ing.
