The Darton Family

6. Rudiments of Conchology (1826; 103 pp., 18 × 10.5 cm) illustrates the breadth of Harvey and Darton’s efforts to provide instructive material for the ‘use of young persons,’ as the title-page indicates. The dialogue form used by this author—styled as a conversation between a father and his daughter—was a typical rhetorical strategy devised to render arcane topics accessible for a juvenile audience.
