    > Lu, older editions of Bowditch have a 15-page chapter "Comparison of Various 
    Methods of Sight Reduction." It's a chronological listing of the various 
    sight reduction methods.
    
    It's expanded to 61 pages in the 1984 edition. The title should have
    said "history and comparison" since the chapter describes many old and
    now obscure methods, including mechanical devices.
