New and correct tables of the lunar motions, according to the Newtonian theory: as it is truly freed from all errors of the press. Which Tables are demonstratively prov'd to be true, by a sufficient Number of Observations, of the most Eminent Astronomers of this and the last Age, viz. Tycho Brahe, Longomontanus, Heveljus, Ricciolus, Bullialdus, Cassini, De la Hire, Dr. Halley, Mr. Flamsteed, Mr. Haynes, &c. Being mostly Observations of Lunar Eclipses, and some of them taken by several of the aforesaid Observers at once. Together, With the Description of a New Instrument for taking Altitudes at Sea, with much more Speed and Certainty than by any Quadrant yet invented; by Means of which Instrument (which may not improperly be call'd an Hypsometer) and the Tables, together with a Book lately printed, entitled, An Humble Address to the Honourable Commissioners, the Longitude may be found, as often as shall be necessary, to the requir'd Exactness: As also, Eclipses may be calculated to the greatest Perfection.
