This is a paper dated ten years after Warfield wrote the article for Julius Tou's book. I don't know whether or not the two articles are related. Rose Warfield found the manuscript when cleaning out the file drawers in Nov. 2000, placed it in a folder and shipped it to GMU, not taking time to read and compare the two articles, even though the titles are so similar they invite comparison. Possibly this paper is the manuscript version of what was sent to Tou in 1957, who knows?
