WILLIAM JOHNSON SOLLAS (1849-1936) SIGNED QUOTE, “W. J. Sollas”, on a card 4 x 1.5, by the English geologist, paleontologist, and anthropologist who was considered one of the true geological polymaths, Sollas worked in a number of areas including the study of sponges, brachiopods and petrological research (how rock were formed), and during his lifetime published 180 papers, and wrote three books. In 1897 he became a professor of geology at the University of Oxford. In 1896 he led the Funafuti coral reef boring expedition of the Royal Society, for the investigation of the formation of coral reefs. As well as his geological and zoological studies he became an expert in anthropology. He won the Wollastan Medal for his 9 papers on sponges. In 1905 he published The Age of the Earth and in 1911 an anthropological work Ancient Hunters and their Modern Representatives. Sollas is known for inventing the serial sectioning device, which made it possible to study the internal anatomy of fossils by removing thin layers of them in cross-section, and capturing anatomy in drawings and photographs. His handwritten quote, in full: “Whatsoever thy hand findeth to do, do it with thy might!” The card is in fine condition, with minor age toning.
