Note 249 — Chapter XIV · THE SPREAD OF EVOLUTION. 1861—1871.
Reading edition
In the introduction to the Descent of Man the author wrote:—"This last naturalist [Haeckel] ... has recently ... published his Natürliche Schöpfungs-Geschichte, in which he fully discusses the genealogy of man. If this work had appeared before my essay had been written, I should probably never have completed it. Almost all the conclusions at which I have arrived, I find confirmed by this naturalist, whose knowledge on many points is much fuller than mine."
