Prof. F. L. Riley, of the University of Mississippi, has, in the Publication of the Historical Society of Mississippi for 1899, an interesting monograph, reviewing the scientific services of Sir William Dunbar, who settled in Mississippi in 1787, and of whom it is stated that he helped to survey the boundary between Louisiana and Mississippi; first directed the attention of the world to the manufacture of cotton-seed oil; made a critical scientific study of the Mississippi river and its Delta; and contributed much to the scientific knowledge of other subjects.
