Ninth Edition. 332 pages. No dust jacket. This is an ex-Library book. Blue cloth with gilt lettering. Library copy, with expected inserts and inscriptions. Black and white illustrations throughout. Minor foxing and tanning to pages. Noticeably heavier and more prominent to text block edges, pastedowns and free endpapers. Light cracking, creasing and staining to gutters; some tangible looseness to binding but pages remain attached.

Lettering remains bright and clear. Book has a slight forward lean.
