The Origin of Species.

First Issue of the Sixth Edition (eleventh thousand). Darwin constantly revised each edition. It is in this edition that the word “evolution” occurs for the first time. It had been used in the first edition of The Descent of Man the previous year, but not before in this work.

8vo. Finely bound by The Chelsea Bindery in full dark green morocco, titles to spine gilt, raised bands, twin rule to turn-ins gilt, plain black endpapers, all edges gilt. Occasional light foxing, an excellent copy.
