    Hughes Tables.

    Additional to my mention of Weems in post 9082:
    
    Lt.Cdr. P.V.H. Weems was responsible for making suggestions to Mr. A.J. Hughes 
    of Henry Hughes and Son, Ltd when on a visit to England in 1936 that resulted 
    in the production by Hughes of what are, in my opinon, the best short-method 
    tables which have been produced, i.e.  "Hughes Tables for Sea and Air 
    Navigation". First published in 1938.
    
    They are compact, being 10" x 6 1/2" (inches) (250 x 165mm) by 3/4" (18mm) 
    thick; and contain other useful tables than sight reduction, such Meridional 
    Parts and Traverse Tables.
    
    They provide a sight reduction to within 0.1 minute accuracy and though not as 
    fast as using the Air tables AP3270, they are almost as fast and provide 
    accuracy an order better than AP3270 which is rounded-up to one minute of 
    arc.
    
    There is only one subtraction and four additions required of numbers taken 
    from the tables.  They are quite easy to use once the simple procedure is 
    learned.
