The full-page color plates are on heavy stock with guard sheets and have the simulated relief texture of an actual specimen. Presentation inscriptions in Vol. I and Vol. II from Richard S.M. Drummond to Eliza Isabella Bryan, dated May 1860. Bound in original figured green cloth, with gilt lettering on the front cover and spine. The backstrip cloth on Vol. II has a repaired tear of 1 ½ in. There is a separation of the final gathering in Vol. I at p. 120, just after Plate 109, the celebrated crouania attenuata, without any broken sewing. The head of the backstrip on Vol. I is worn. The book blocks of both volumes remain solid and secure.
Few books were printed using this early process to reproduce directly from the specimen itself, as the then-new process was first developed by Alois Auer in Vienna. Henry Bradbury visited Vienna and brought the process back to the United Kingdom. The specimen was placed between a lead plate and a steel plate. Colored ink was then applied to the lead plate, which allowed a great advance in detail in the reproduced image. This process was transitory to better and more economical methods of mechanical mass reproduction.
