Keill, J. Introductiones ad veram physicam et veram astronomiam. Leiden, J. and H. Verbreek, 1725. 4°. With engravings by Tvign. and 47 folded copperplate engravings. 2 leaves, 636 pp., 5 leaves of contemporary leather with gilt lettering (front cover loose, back cover detached, parts slightly worn and rubbed). Poggendorff I, 296. Houzeau-Lancaster 9247. — First complete edition of the two major works by the British mathematician and physicist John Keill (1671–1721). His *Physica* was published as early as 1701, while *Astronomia* did not appear until 1718; this edition brings together the two works—based on his lectures at the University of Oxford—for the first time. Keill was a vehement defender of Newton in his dispute with Leibniz over priority in the invention of calculus, accusing Leibniz of plagiarism in the *Philosophical Transactions of the Royal Society*. - Cover slightly discolored, somewhat tanned, with a few scattered spots.
