Thomas Henry Huxley was an English biologist (comparative anatomist). He was the most effective supporter of Darwin's Theory of Evolution and had a strong interest in scientific education — in schools, universities, and for the general public. He has been described as «the premier advocate of science in the nineteenth century [for] the whole English-speaking world». This volume consists of popular lectures he gave on biology and geology and addresses he delivered on the same subjects to scientific bodies.
