Principles of Descriptive and Physiological Botany - John Stevens Henslow - Bog

J. S. Henslow, Charles Darwin's mentor, was professor of botany at Cambridge. He was an inspirational and innovative teacher who nurtured independent inquiry and acute observation in his students. This liberally illustrated 1835 text on the nature and stability of 'species' reflects the influence of Candolle, and in turn influenced Darwin.
