    The exact title from the article itself:
    III.  Recherches sur les pricipaux Problemes de l'Astronomie Nautique.
    Par Don Josef de Mendoza y Rios, F.R.S. Communicated by Sir Joseph
    Banks, Bart. K.B.  P.R.S.
    His introduction to direct methods around page 79, seems quite clear.
    The fundamental equation is really a very straight forward combination
    of sines and cosines.  Programmed it up in excel in 20 minutes and can
    reproduce the web calculator results.  He then spends considerable
    effort recasting the equation into 40 different forms to facilitate
    rapid solutions with logs and tables.
