Lund, Berlingian, 1797. Small 4to (19.7 x 15.0 cm). 17 pp. Marbled spine cover. Published without wrappers.

A rare thesis containing observations concerning the crocodile and its history. Written by the Swedish botanist, entomologist, herpetologist, and professor of natural history at Lund University, Anders Jahan Retzius (1742-1821) and defended by his pupil, Matthias Jacobsson, from Kalmar (1774-1836?). This copy, although without owner's inscription or stamp, from the library of the renowned Swedish herpetologist Richard Wahlgrén (1946-2019), who had a keen eye for herpetological rarities. Title a bit soiled in the margins, otherwise, a very good, clean copy.
