An epitome of theoretical and practical navigation containing a complete system of that art, greatly improved, (and widely different from the present laborious, and, in some respects, erroneous Method of Teaching) from self-evident Demonstration, founded on many Years Experience in the several Voyages made by the Author; more particularly, That to St. Helena, when appointed by the Royal Society, to observe the transit of Venus over the sun. This Work is arranged under the following Heads, in a more easy and accurate manner than any hitherto published, viz. Chronology; the Theory of Tides; magnetism, and the variation of the needle; Geography, with a large Table of the Latitude and Longitude of Places in Europe, Asia, Africa and America; together with the Times of High Water at the principal Places; Geometry; the construction of logarithms; plane trigonometry, with their Application to Navigation; The Method of making Sea Charts, finding the Latitude and Longitude of a Ship, and the Variation of the Compass: With a new table, shewing the Times of the Rising and Setting of the Sun, Moon and Stars; Also the Manner of finding the Lee-Way, the Set and Drift of Currents, and to Correct the Dead Reckoning, &c. All of which are exemplified in a journal from the Downs through the Channel, from the Lizard to Madeira, and from Teneriff to S.. Helena, with the Author's Remarks thereon; As also the Form of keeping a Journal, and of collecting, with the greatest Facility, the Particulars thereof. By Robt. Waddington, teacher of Mathematics, Late Mathematical Master of the Royal Academy at Portsmouth
