Thanks for that information. I should have been clearer that I did not see any conflict between your first post and the information I was giving--and I had not known about the individual glass cups beginning to be used as early as 1854! I guess the temperance movement and the "germ theory" were co-existent!

Thanks for that post--that reference book you are using appears to be fascinating. I may have to look for it in a library.
