He initially turned to petrology and worked as a laboratory assistant in the iron and steel industry. After an accident at work that made it impossible for him to work continuously, he worked as a petrologist and field geologist for the British Geological Survey . At his alma mater , the Royal School of Mines, he was professor of geology from 1876 to 1895. In 1877 he was elected a Fellow of the Royal Society , and between 1886 and 1888 he was President of the Geological Society of London . Among his students were the geologist, polar explorer and surveyor Edgeworth David and the paleontologist Frederick Chapman .
