Epistola ad illustrem et excellentissimum virum dominum Godofredum Guilielmum Leibnitium polyhistorem consummatissimum qua characterem plantarum naturalem nec a radicibus nec ab aliis plantarum partibus minus essentialibus, pluribus discriminandi capitibus constitutis, peti posse ostendit simulque in comparationem plantarum quam partes earum genitales suppeditant paucis
A Latin scholarly letter on plant classification, written by Johann Heinrich Burckhard and Lorenz Heister and printed in 1750 by the Weygandiana press, addressed to the polymath Leibniz. The pictures are small woodcut typographic ornaments: scrolled cartouches, a vase of flowers, and framed initial letters, cut in a crisp, simple line style that a designer could borrow for decorative capitals and border devices.
