The mariners new kalendar, containing the principles of arithmetick and geometry; with the extraction of the square and cube roots. Also Rules for finding the Prime, Epact, Moon's Age, Time of High-Water, with Tables for the same. Together with exact tables of the sun's place, declination, and right ascension. and Declination of the Principal Fixed Stars. Of the Latitude and Longitude of Places. A large Table of Difference of Latitude and Departure, for the exact Working a Traverse. Also, the description and use of the sea-quadrant, fore-staff, and nocturnal. The Problems of Plain-Sailing and Astronomy, wrought by the Logarithms, and by Gunter's Scale. A Tide Table. The Courses and Distances on the Coast of Great Britain, Ireland, France, &c. And the Soundings coming into the Channel. With Directions for sailing into some Principal Harbours. By Nathaniel Colson, Student in the Mathematicks[.]

The new practical navigator; being an epitome of navigation, rendered easy to any common capacity: containing all the requisite tables for determining the latitude and longitude, and keeping a complete reckoning at sea: Illustrated by Proper Rules and Examples, the Whole Exemplified in a Journal Kept from England to the Island of Teneriffe. So that this Book, and the Nautical Almanac, will be Found Fully Sufficient for the Seaman and Teacher's Use. Constructed on a New Plan. By John Hamilton Moore, Teacpcr of Navigation, Hydrographer and Chart-Seller to his Royal Highness the Duke of Clarence.

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 longitude demonstrated, by the use of a silent pendulum; that keeps true time at sea. And made plain (by an Index Instrument) to the meanest Capacity. With a new observatory for finding the meridian altitude of sun or stars, and a great Improvement of the Sun-Quadrant; which are more exact than any heretofore known: With fair Copper Cuts of the Machine, and all the other Instruments. And a table of the acceleration of fixed stars, more exact than any heretofore extant; with the Sun's Declination, Right Ascension, and Equation of Time; and other useful Tables fitted to this Work. An Experiment of what Proportion a Pendulum lengthens in the greatest Heat, where Animals can live, or Vegetables grow; and at several other Degrees of Heat, to red-hot. With a Method to make a Pendulum to fit all Climates; with several other uncommon Experiments. By Jonah Crathorne.

The navigator's guide, to The Oriental or Indian Seas: or, the description and use of a variation chart of the magnetic needle, designed for shewing the longitude, throughout the principal parts of the Atlantic, Ethiopic, and Southern Oceans; Within a degree, or sixty miles. With an Introductory Discourse, concerning the Discovery of the Magnetic Variation, the finding of the Longitude thereby, and several useful Tables. By S. Dunn, Teacher of Mathematics, London.
