    Bowditch has tables of Meridional Parts to quite a number of decimal places.
    The method for computing distances using Meridional Parts is called "Mercator
    Sailing" and is also described in Bowditch.
    The introduction to the tables in Bowditch gives a formula for computing
    Meridional Parts.  I have programmed this into a calculator.  One could also
    program it into a spreadsheet.  If memory serves me correctly (I'm away from my
    home library) there is a typo in the formula in Bowditch 95, but Bowditch 80/84
    Volume 2 has it right.
