THE death occurred in Toronto, on October 3, of Prof. W. A. Parks, professor of geology in the University of Toronto. William Arthur Parks was born in Hamilton, Ontario, in 1868, and educated in Bowmanville High School and the University of Toronto. With his university he was to be associated for the rest of his life, and his career is a long list of ascending responsibilities. He graduated B.A. in 1892, became a ‘fellow of geology’ in the following year, and was in turn instructor, lecturer and, in 1905, associate professor. In 1913 he was appointed director of the newly constituted Royal Ontario Museum of Palaeontology, an institution which has greatly developed under his guidance. From 1916 until 1922, Dr. Parks was professor of palaeontology and in the latter year he was promoted to the full chair of geology.
