    Dear Dan,
    
    I don't know where you got a hold of an 1888 Bowditch, but the place I was 
    searching (abebooks.com) had only three before 1900, all $1000 and up.  And I 
    already own two Bowditch's, and just want the one section in any case.
    
    So, if you want to do us all a HUGE favor, and have a scanner, you could scan 
    in the pages and have Dan Hogan (or me) put it up on our websites.  That way 
    everyone could have it, and we will then be able to puzzle out how to do a 
    lunar.
    
    cheers,
    Dov
