Next message: Henry C. Halboth: "Re: Martelli's Navigational Tables"
Victor
My tables, i.e., 1914 edition, encompass only 52 pages, and contain no
frills, although it is possible to adapt them to an intercept method and
to make other calculations by the substitution of values. I have always
considered Martelli's formulation to be innovative and interesting,
although for many years my short tabular method of preference was
Dreisenstok, which superceded my use of Martelli. Thanks for an
interesting side track to methods of yesteryear
