	Have fun with Smythe - you're a braver man and far better mathematician
than I am!  I am nearly positive that I found a site from which you can
download those Bulletins (Official title: Bulletin of the Bureau of
Standards) but I can't find it again.  I suspect that your library
should be able to borrow a copy from many university libraries, and
perhaps the Library of Congress.  Out here in LA I'd call the UCLA and
Caltech libraries.  In the past I have been able to borrow books from
the Library of Congress, but don't know if that's still possible.  As
for finding an original to purchase, that's going to be a harder deal.
