First Principles

Herbert Spencer · Williams and Norgate (London) · 1862

Do not confuse the plain 1862 first edition with Spencer's subsequent revised editions of First Principles, culminating in the sixth and final edition of 1900 (revised by the author, D. Appleton and Company), whose title pages carry an explicit revision statement absent from the 1862 original.
