DETAILED CONDITION
Binding
The leather and sides are abraded, darkened, and skinned, mainly at the tail and foredge. The
headcaps at both head and tail are worn and skinned, with the fold missing from both. The
board edges are exposed at head, foredge, and tail, delaminating and eroding throughout but
primarily at corners. The leather at the corners is lifting, in some areas up to 5cm, with
skinning and large losses. The right joint is broken, but the case is intact. There is a coarse
cloth patch lining, with the patches at the head and tail attached to the case but not the
spine, and the center patches adhered to the spine but split at the joint. The endband cores
are split. There is a 2cm stain at the tail of the left board, and a 1cm dent at the foredge of
the right cover.
Text Block
The textblock is discolored as if by smoke or pollution, with flecks of something resembling
soot, primarily at the foredge and where charts were inserted. The right flyleaf is detached,
and the first folio is split. Pages 7 and 8 are glued together, although this seems intentional,
because the page numbers repeat on the following page. The charts are more darkened than
the textblock paper. The flyleaves are brittle. The pages to which the flyleaves are tipped are
cracking near the tipped area.
