Lipsiae, Immanuel Titius, 1724. 4to (19.0 x 16.4 cm). Title page, dedication leaf, index and corollaria.; 24 pp.; engraved plate. Without wrappers, as published.

A seldom-seen early work on frogs and their anatomy, defended as a thesis by the German botanist and zoologist Caspar Bose (the younger) (1703-1733), and dedicated to his father ([1672-1730], a botanist of the same name), and uncle, the jurist Johann Jacob Bose (1678-1741). Bose's supervisor, and, in a northern European tradition, the actual the writer of the work, was the professor of philosophy and - later - physics, Johann Friedrich Menz (1673-1749). Apparently a very early edition, as the title contains an erroneous blank space between the (Greek) o and s in paradoxos, corrected in a later edition. The plate a bit shaved, with minimal loss, otherwise a very good, clean copy. We found no auction records. Neither in Nissen nor in Cat. BM(NH).
