Half leather on marbled boards, gilt titles. All plates present, including two coloured; many of the illustrations referred to as vignettes by Gell are present as tipped-in mini-plates. The Imperial Octavo edition, 258 mm high. Condition: Externally both volumes are in a poor way; spine strips have parted from rear boards, leather is very rubbed, spine strip of Volume 2 split. Volume 1 has both boards detached, text block sound apart from first few pages as noted above. Volume 2 is similar, (ie both boards detached) but only the frontis is detached with the front board; binding is strained at one point. Plates overall in very good condition, with blank leaves as guards (not tissue guards); there is a general tendency to age darkening but only one or two of the plates are significantly browned or foxed. Particular exceptions are the Portrait and frontis of Volume 1, which are detached (the latter with title page and first leaf of Contents lists), with foxing and rolled edges and the frontis of Volume 2, which is detached and badly foxed. More detailed photographs on request.
