Thomas Henry Huxley, best known for his public defence of Darwin, was another polymath who once thanked the gods for his "diversity of tastes", declaring that "if I had as many lives as a cat, I should leave no corner unexplored". Like Darwin, Huxley studied medicine, but did not take a degree. Like Darwin, his life was changed by an expedition, in his case to the Torres Straits and Australia between 1846 and 1850, as surgeon on HMS Rattlesnake. Huxley became interested in zoology, carrying out research on sea anemones, jellyfi sh and sea urchins. On his return to Britain, Huxley taught geology as a lecturer at the School of Mines in London. Geology and a concern with evolution led him to palaeontology, studying dinosaurs and the skull of a Neanderthal man. Following a meeting with Herbert Spencer, Huxley was introduced into the circle of the Westminster Review and came to write for it regularly, discovering a gift for lucid and vivid popularization. He also gave public lectures on a wide variety of topics, including the famous lecture, "On a piece of chalk", delivered to the working men of Norwich in 1868. Huxley’s collected essays and lectures run to nine volumes and include a debate with Matthew Arnold over the relative place in education of literature and science.
