Cambridge Phil. Soc. 67 (1970) 553-558. I believe Sammy's paper was for an MAA expository series. It sounded a beautiful approach but I did not see the manuscript and forget the details. While the paper was in the universal categorical spirit it made only one parenthetic remark that something was a category. Sammy claimed this was why the paper was rejected. What a great pity! I would love to have a copy of the preprint. Does anyone else know about it? --Ross
