    Re: Certaine Errors in Navigation Corrected

    Thanks to Gary LaPook for bringing to our attention that treatise by Wright,
    and the puzzle his diagrams represent.
    There's been little or no reponse so far, and perhaps that's because others,
    not just me, have been struggling to understand what's behind Wright's
    I agree with Wright that his first construction, in the case where the
    departure point and the destination are at the same latitude, gives an exact
    answer. He proposes a second, different, construction when those latitudes
    differ. However, if you then apply that second construction to the
    special-case where the latitudes are in fact the same, it should boil down
    to the same thing as the first construction. I'm not sure that it does. So
    I'm not convinced yet that he has got things right. Could there be another
    typo in his text, perhaps, or in the labelling of his diagram?
