    George asked me to provide some pages from Tables Requisite 1781. I believe
    that the link to Google provided by Paul solves George's request. Otherwise
    please let me know. I have the 1781 edition in pdf and can distribute it to
    NavList if desired. I think I found it on Google some years ago.
