A compendious system of astronomy, in a course of familiar lectures; in which the principles of that science are clearly elucidated, so as to be intelligible to those who have not studied the mathematics. Also trigonometrical and celestial problems, with a key to the ephemeris, and a vocabulary of the terms of science used in the lectures; which latter are explained agreeably to their application in them
Margaret Bryan's 1797 astronomy textbook, printed for the author in London and written for students without mathematical training, sets out lectures on celestial motion, trigonometry and optics. Engraved plates group numbered figures on one page: ray diagrams through lenses and the eye, gridded celestial globes, planetary orbit circles, protractor arcs and triangles, all in fine line on cream paper.
