The elements of conchology; or, natural history of shells. According to the Linnean system. With observations on modern arrangements / By Thomas Brown ... Illustrated with nine coloured engravings.
An 1816 London introduction to conchology by Thomas Brown, arranging shells by the Linnean system for students and collectors, with nine engraved plates. The plates group numbered shells against blank paper within ruled borders, some left as outline line engravings with lettered reference marks, others hand-coloured in ochre, crimson and pale grey; useful for spiral and bivalve silhouettes, hatched shading, and specimen-grid layouts.
