Second edition, preceded by the first edition of 1781, the success of which "induced the author to bestow some labour and attention in revising, correcting, and improving this Edition; to which he has added a copious Glossary of the technical terms" (Introduction). The plates were engraved by James Newton from McArthur's own drawings. Only 130 or so copies of this edition were subscribed for. Pardoel 428; Thimm p.172.
