549 pages, pus six pages of advertisements for The Minerva Library. Includes index to Coral Reefs. Red boards with gilt title 'Coral Reefs Darwin' within a gilt in border, repeated on the spine also in gilt print. Six plates. three of which are foldout maps. The front board is chipped towards the middle of the tail; pages ix-xiv are lightly bumped towards the middle of the outer edge, xi- xii also suffering from a minute short tear. From page 17- 90 the head's outer edge is bumped and creased. The bump and the crease, which is quite small, increases in severity, easing off towards the last seven pages. pp 67-68 additionally suffer from a tiny closed tear caused by the creasing. From page 441-480 the tail of the page is creased, at its nastiest from page 463-471. Neat ownership signature on the verso of the front end paper. The faults are not pretty, but for the rest a clean, unmarked and solid copy, which I think is fair to call very good. No publication date offered, I have taken 1896 from Trove. Full title: " On the structure and distribution of coral reefs : also Geological observations on the volcanic islands and parts of South America visited during the voyage of H.M.S. Beagle / by Charles Darwin ; with portrait, maps, plates, and numerous illustrations and critical introductions by Prof. John W. Judd."
