Edinburgh: Lizars. hardcover. 1 volume (XXVII) from the impressive 40 volume set. Frontispiece portrait of the naturalist Buffon. Extra illustrated title page, and 30 fine hand-colored engravings, protected by tissue. The plates are all masterfully engraved by William Lazars who used steel, rather than copper plates, to preserve the fine detail on the small-format pages. 288pp. 12mo, handsomely bound in contemporary dark green polished calf over plum cloth; ornate blind and gilt-stamped spines with burgundy leather labels; marbled page edges (one plate is damaged at edges; cloth is partially faded on front cover; one leather label is chipped; still a very good copy). Edinburgh: Lizars. London: Highley & Nelson. Dublin: Curry. Manchester: Ainsworth, (no date, circa 1850). very good.
