Miscellanea Berolinensia ad Incrementum Scientiarum [...].
4to. (16), 392 pp. (12), 188 pp. With engraved frontispiece, 40 engraved folding plates, and several illustrations in the text. Later marbled wrappers.
Two issues, in one volume, of the scientific periodical of the Berlin Academy of Sciences, containing remarkable contributions by Gottfried Wilhelm Leibniz. It includes the second printing of Leibniz's description of his famous calculating machine: the first stepped-drum calculator, being the first machine that could perform multiplication and division - an invention of major importance in the history of computing. This text, entitled "Brevis descriptio machinae arithmeticae", was first published in the "Miscellanea" in 1710. Further, the 1749 issue includes a notable treatise on the game Go, also by Leibniz, illustrated by a folding plate showing two Japanese men playing this game.
Among the other contributors are the mathematicians Jakob Hermann and Philipp Naudé the younger, as well as the astronomers Johann Wilhelm Wagner, Christoph Langhansen and Gottfried Teuber.
The plates show Leibniz's calculating machine as well as fossils, celestial bodies and eclipses, a threshing machine, medals, and calculations with geometrical sketches.
Somewhat browned throughout. A fine copy of two publications reflecting the active academic scene of Berlin.
