    George mentions that the 1780 issue of the Tables Requisite isn't scanned
    into Googles. I believe that the edition should be 1781, which is available
    on Googles. Further, my understanding is that there is no edition published
    in the time span 1767 to 1781.
    
    Kent is right, and I was careless, in stating 1780 without checking, when 
    it should have been 1781.
    
    However, I've taken another look at Google Books, which appears to confirm 
    that the only full view it provides me of Maskelyne's Tables Requisite is 
    of the 1802 edition, and the 1781 edition is available to me here as "book 
    overview" only, which prevents it being read. Unless I'm misunderstanding 
    something, which is all too possible.  My own access to the first edition 
    of 1767 is via a (facsimile) print.
    
    If Kent has better access to the 1781 ed. than I do, I wonder if it might 
    be possible for him to look in and select for us the appropriate page or 
    two that Frank was referring to. It would come somewhere in the examples of 
    how to clear a lunar distance (perhaps by more than one method) and should 
    be readily identifiable by its value of apparent lunar distance between 
    centres of 108� 30' 08".
