A Treatise of Navigation [electronic resource]: Containing, I. The Theory of Navigation Demonstrated; Wherein It Is Proved, That the Nature of the Thing Called Departure Is Quite Different From That Which the Writers Upon This Subject Took It to Be: That Middle-Latitude Sailing Is Erroneous; And That the Common Method of Keeping Reckonings in Meridional Distance, Is Grossly False. II. Nautical Problems: Of a Single Course, Traverses; Of Computing the Bearings and Distances of Places. The Use of Mercator's Chart Made Easy, and a New Method for Finding the Bearings of Places Upon Charts, Without the Confusion of Rhumb-Lines. Of Currents, and How to Find Them Several Ways: Of Turning to Windward in Currents, &C. III. Astronomical Problems: Improvements Made in the Common Sea-Quadrant. The Description of a New Fore-Staff, Which Is Much More Accurate and Commodious Than the Common One. The Errors of the Nocturnal Shewed and Demonstrated. Tables of the Sun's Place, Declination, and Right Ascension. A Table of the Most Eminent Fixed Stars, Contrived in Such a Manner, as to Shew by Inspection, Which Is the Properest Star for Observation, in All Places, and at All Times of the Year. IV. Practical Navigation: Improvements Made in the Common Sea-Compass. The Description of a New Azimuth-Compass, Which Is So Contrived as to Be Kept From Being Disturbed by the Motion of the Ship. How to Find the Lee-Way to a Great Exactness, and a New and Commodious Method of Keeping a Sea-Journal. To Which Is Prefixed, by Way of Introduction, a Succinct Treatise of Plain Trigonometry. By Joseph Harris, Teacher of the Mathematicks
