Astronomy of the satellites of the Earth, Jupiter and Saturn Grounded upon Sir Isaac Newton's Theory of the Earth's Satellite. The Theory explain'd, and made easy to the meanest Capacity, in calculating the true Place of the Moon: And freed from the Errors printed in the said Theory, by Dr. Gregory, Dr. Harris, and several other Authors for which now the Place of the Moon, and Eclipses of the Luminaries, are found to a very great Exactness. Also New Tables of the Motions of the Satellites of Jupiter and Saturn, (founded upon the Observations of Mr. Flamsteed, Mr. Cassini, Mr. Hugens, Dr. Halley and Mr. Pound,) from the Vernal Equinox: By which their Places and Positions, in respect of one another, may be exactly determined at any given Time. Adapted to the [illegible] of London. To which is added, A Problem to find the Latitude of the Place by the Altitude of the Sun, Moon, or Star, upon any Azimuth; being very useful for all Sea-Faring Men, as well as Gentlemen and others.
