THE KNOWLEDGE OF THE HEAVENS AND THE EARTH MADE EASY : OR, THE FIRST PRINCIPLES OF ASTRONOMY AND GEOGRAPHY EXPLAIN'D BY THE USE OF GLOBES AND MAPS …

London : for J. Clark & R. Hett; E. Matthews, and R. Ford, 1726. First edition. A popular and much reprinted text, with very clear expositions and worked examples of the problems and principles, intended to lead on "to the higher speculations of the great Sir Isaac Newton and his followers". Dedicated to John Eames (1686-1744), recently elected to the Royal Society on Newton's recommendation and himself a serious scholar of physics. "The same perspicuity of thought and ease of expression which distinguish his other works running through the whole of this, I don't question but the world will meet with equal pleasure and satisfaction in the perusal" (from Eames's preface). Watts was perhaps better known as a hymn-writer, but was also the author of such works as "Logic, or The Right Use of Reason in the Enquiry After Truth" (1724), which became the standard text on logic at Oxford, Cambridge, Harvard and Yale. Post 8vo (196mm x 16mm), [2](xiv),(220)[xii]pp. Title-page in red and black, six folding plates. Contemporary full calf, silk headbands; rebacked, labelled, banded and gilt to style; sprinkled edges; some light wear; neat repair to title-page, not affecting lettering; some occasional internal marking and spotting; small ink stain to fore-edge but a good, sound and attractive copy of an important and accomplished work, particularly good on the use of maps and globes.
