Hi. Thanks very much for your trouble. I did find these on the WEB searching I did. The library in Zurich will let me look at it if I join, and they will even send it to the EPFL library in Lausanne (an hour from where I live) but in either case, I will not be allowed to take it out of the reading room. Maybe one day I shall just go and read it there over a couple of days. But I would love to find a copy that someone has lying about unloved on their bookshelves! Thanks again and kind regards, Carol
