London and Worcester: S. Crowder and S. Gamidge (1765, 1766, 1765), 1765. Hardcover. Good. Three volumes bound in one, first edition of the first and third titles, second edition of "A View of the Earth", quarto size, [160] pp., illustrated with maps and globes. Following his matriculation from Magdalen Hall, Oxford in 1748, Richard Turner (1720-1791), English clergyman and educational writer, became chaplain to the countess dowager of Wigton, and in 1754 was instituted vicar of Elmley Castle in Worcestershire; in June of the same year he was appointed rector of Little Comberton. Turner was the author of a number of educational texts, including "The Young Gauger's Best Instructor" and the first edition of one of the present works, "A View of the Earth", which appeared in 1762.

The present copy includes the first edition of his introductions to trigonometry and astronomy, both published in 1765; later works included a similar volume on geometry and a study of education. The maps in the Geography volumes include a double-hemisphere frontispiece and maps of the continents of Europe, Asia, North America, South America, and Africa by John Gibson; the "Astronomical Clock" on page 41 of the "A View of the Heavens" is lacking the printed volvelle used to determine the hour of night from the position of the stars. A scarce trio, the trigonometry volume particularly so with no copies appearing in recent auction records.
