Very rare. Published anonymously but attributed to Modeer by LKG. The text portion contains the authors discussion on the order of nature. The systematic part treats the authors mineral system comprising six classes divided into orders and species. Next to each species there is a page reference to the works of Linnaeus, Wallerius, Cronstedt and Bergman. \JKjellman

This "first edition" is very much like the second except that there is no systematic part. \JKjellman
