• A supplement to the royal astronomer and navigator. : Supplying (by reduction and equation) accurate astronomical tables; tabuld̆unelmenses, greenovicenses, &c. With a general and accurate solution of the longitude problem, or the effect of parallax and refraction, in distance, truly determined. Compared with the solutions of the same problem, in the nautical almanac and ephemeris, for finding the longitude at sea. By R. Heath, author of the Royal astronomer and navigator.

• Navigation compleated : Being a new method never before attain'd to by any. Whereby the true longitude of any place in the world may be found, whether differing in longitude only, or both in longitude and latitude from any place in the habitable world, by new invented mathematical instruments, viz. The complete navigator, or universal chart. The accute astronomer, compass, admitting of no variation in any latitude, &c. distance-reel and discoverer. By the uses whereof, the certainty of the easting and westing of the globe may be discovered as exactly as the northing and southing already are, and to give at any altitude (having the suns declination, the true latitude, longitude, hour and azimuth all at once by ocular inspection, thereby making the sea barring winds, &c. as direct and plain a path for ships to sail, as the land for travelling. By Francis Cawood, London, student in the mathematicks.
