Containing the three Decades of plates and descriptions relating to trilobites: Decade II, published in 1849; VII, published in 1853, and XI published in 1864. Bound together in black cloth-covered boards, gilt titles to spine, gilt stamp of King’s College London to front board, all edges red-deckled. An ex-library copy, originally from King’s College (University of London), subsequently belonging to Royal Holloway College, (also University of London). Condition: Boards rubbed and bumped, with the cloth wrinkled on the top board (I suspect a manufacturing fault rather than later damage). Various library stamps to prelims including occasional stamps to verso of plates. Library label to spine, taped over the original gilt library shelf mark. Spine strip frayed at top and bottom, and joint worn for top inch or so between spine strip and back board. Pages age-toned, but clean and unmarked, with just a little spotting here and there. All plates in very good condition. Binding sound.
