The Physiology of Common Life by George Henry Lewes 
Bernhard Tauchnitz, Leipzig, 1860. xii, 315, viii, 351 pp. 12mo. Many woodcuts in text. "Copyright edition". Head of spine repaired with tape. Leather scuffed, sadly. Although the binding remains strong and, apart from an owner's inscription, the text block is clean. Quarter leather. Good.
An early Victorian attempt to approach a comprehensive introduction of physiology for the common reader. Lewes is now best known for his common-law attachment to Marian Evans [George Eliot]. It is argued that his work influenced the scientific characters in her work.
