The description and use of a new much-improved sinical quadrant, whereby, A Person knowing Addition and Subtraction only, may learn, in Six Hours, to allow for Variation and Lee-Way, &c. Also, determine the Longitude at Sea, and keep a regular Journal of a Voyage to any Part of the World. This Instrument is equally useful in Altimetry, Surveying, &c. for taking Altitudes, and determining right angled Triangles. Invented by John Adams, at the Academy, In Brook-Street, Ratcliff; And Made by Richard Rust, Mathematical-Instrument-Maker, St. Catherine's, London.

The mariner's compass rectified: containing tables, shewing the true hour of the day, the sun being upon any point of the compass: with the true Time of the Rising and Setting of the Sun and Stars, and the Points of the Compass that the Sun and Stars rise and set with: And Tables of Amplitude. All which Tables are Calculated from the Equinoctial to 60 deg. of Latitude, &c. With the Description and Use of those Instruments most in Use in the Art of Navigation. Also a Table of the Latitude and Longitude of Places: By Andrew Wakely, Math. Carefully corrected, and very much enlarged, with many useful Additions. By Ja. Atkinson, Teacher of the Mathematicks. To this Dublin edition is added, The complea boat-swain. By Henry Bond.

The description and use, of a new quadrant, for finding the latitude at sea: Invented and made, by Benjamin Cole, mathematical instrument-maker, at the Orrery in Fleetstreet, London, to which are added short and plain instructions, for the use of that most excellent instrument, invented by John Hadley, Esq; with the improvement of an artificial horizon.

A treatise of navigation: 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.

The description and use, of a new constructed octant, sextant and quintant. By His Majesty's patent, being an improvement on the Hadley's quadrant. By either of which, altitudes are taken, and angular distances measured to the greatest precision from 0. to 160ʻ. Without a back observation, and with double the space of illumination, or field of view: also a new meth[o]d of adjusting the glasses, and applying the instrument for the purposes of finding the latitude and longitude at sea..
