The young trigonometer's new guide; containing The Elements of Plain and Spherical Trigonometry, deduced from the Principles of the Sphere in a Method entirely new; with the Analogies for solving all Cases, and Varieties of Triangles in every Way hitherto invented; with their Application to Practice. Together with The Principles of Fluxionary Trigonometry fully explained and exemplified in many useful Problems. also The Laws and Rules of the Stereographic Projection of the Sphere explained, and applied to the Delineation and Solution of Spherical Triangles, and the Construction of Maps and Dials. Illustrated by four copper-plates. By B. Martin.

A treatise of trigonometry, plane and spherical, theoretical and practical. In which the several cases of plane and spherical triangles are solved, instrumentally and arithmetically. As likewise a Treatise of Stereographick and Orthographick Projection of the Sphere. In which the Principles and Theorems on which they depend, are clearly Demonstrated, and the Practice naturally deduced from those Demonstrations. Illustrated in the Stereographick Projection of the several Cases in Right and Oblique Angled, Spherical, Triangles: So that the Requisites may be found without Calculation, by Scale and Compass. The second edition, carefully corrected by the author Sam. Heynes, Teacher of the Mathematicks.

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.
