Nicola Telsa references the said patents applicability in the methods of nauvigation. Within his rather long winded prose he states
> the course of a vessel may be easily be determined without the use of a compass, as by a circuit connected to the earth at two points, for the effect exerted upon the circuit will be greatest, when the plates PP are lying on a meridian passing through ground-plate E and will be / when the plates are located at a parallel circle. If the nodal and ventral regions are maintained in fixed positions, the speed of a vessel carrying a receiving apparatus may be exactly computed from observations of the maxima and minina regions successively traversed.
Doers of projective geometrie, if ye be so inclin'd to offer your trauvailles it would be of most appreciation.
As one may be aware. The earth, in her dimensia, neglects the ordinance the perfeccion of the sphere. Ay! one must call it but a spheroid! While of little concern to the methods of navigation and cartography by the declension of the fix'd starres by means of the astrolabe, the timing of the light of the lunar eclipse, or by the transit of mercury, such methods doth lit by our dearest natural philosopher demands Jove's keenest discernment, for the geometrie of his heavenly bodyies would yield an effect on the measurement obtayned by such a method.
In short I must yield error corrected projections of the 'globe' in a variety of wonders mathematicall. Mercator, Werner, Ptolemy, thine desire is to witnesse, side by side, the cartographers projection onto a sphere, and than onto the spheroid. Than perhaps my hypothesis upon the origins of Piri Reis can be made clear.
Much Thanks, Ye philosophers
