Note 229 — Chapter XIV · THE SPREAD OF EVOLUTION. 1861—1871.
Reading edition
Mr. Huxley was as usual active in guiding and stimulating the growing tendency to tolerate or accept the views set forth in the Origin of Species. He gave a series of lectures to working men at the School of Mines in November, 1862. These were printed in 1863 from the shorthand notes of Mr. May, as six little blue books, price 4d. each, under the title, Our Knowledge of the Causes of Organic Nature.
