Download A Treatise of Navigation: Containing, I. The Theory of Navigation Demonstrated ; Wherein it is Proved, that the Nature of Theing 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 Teh 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.

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.
