Well scribd asks for registration to download. So after a little search, I've found the 2nd Edition here:

BTW: The first edition of this book is most certainly out of copyright, Van Nostrad would had to have filed a copyright renewal in 1959 which most did not at the time.
You might get asked to remove the link, and, after refusing, have your post killed. That's unlikely, but could actually happen. But who cares?
