• A new and easy method to find the longitude at land or sea : From the observation of the altitudes of the c D oelestial bodies only; without having any recourse to eclipses, the satellites of Jupiter, the doctrine of appulses, or the magnet; and without the use of clock-work, dials of any fort, sand-glasses or pendulums; or any other instrument, but a sextant, quadrant, or astrolabe

• The longitude discovered by the eclipses : occultations and conjunctions of Jupiter's planets. With descriptions of those Refracting and Reflecting Telescopes; and of those Sectors, and that Quadrant, which are the Instruments necessary for this Discovery, both at Land and Sea. To which is added, An Ephemeris for the latter Half of the year of our Lord 1738. Containing the Configurations of Jupiter's Planets at Six a Clock every Evening, while Jupiter is to be any where seen. With those Eclipses, Occutations, and Conjunctions that are useful for the Discovery of the Longitude, both at Land and Sea. Engraven on a Copper Plate. Humbly Recommended to The Honourable the commissioners appointed by Act of Parliament for the Discovery of the Longitude at Sea. By Will. Whiston, M. A.

• A supplement to the treatise for finding the longitude : Containing all the requisites for the ready computing and obtaining the longitude of a ship or place, by observations of the sun and moon. (The tables of the requisites are for the year 1764.) To which are added, tables of the declination of the sun, and of the variations of the declinations, &c. whereby the true declination of the sun may be had at any given time for a century to come. Also, the most practical method of obtaining the variation of the compass, or magnetic needle.
