Beschäftigungen der Berlinischen Gesellschaft Naturforschender Freunde. (4 vols.)

Within two years of its founding in 1773 the Gesellschaft Naturforschender Freunde zu Berlin (the Natural History Society of Berlin) became one of the most active and important scientific organizations of the 18th century. Its journal, the Beschäftigungen (4 volumes, 1775-1779), contains approximately 120 articles by a roster of prominent European naturalists, covering zoology, mineralogy, geology, conchology, scientific instruments, astronomy, and other scientific subjects, as well as catalogues of the Society's library and cabinet of natural-history specimens.
