Loxodromic, lok-so-drom′ik, adj. pertaining to certain lines on the surface of a sphere which cut all meridians at the same angle, and indicate the course held by ships in rhumb sailing.—Loxodromic curve, line, or spiral, the course of a ship oblique to the equator and cutting all the meridians at the same angle, sailing constantly toward the same point of the compass.—Loxodromics, the art of such oblique sailing.

No one knew what an "isometric equatorial projection of a loxodromic curve" was, or seemed to care.
