Turner, R.A.,” Sampson Low, 1897, p. 27. Of the many biographies of Turner, this, although slight, gives probably the best and truest view of him and his work. [B] Turner’s conception of nature, I may remark, is identical with that of Sir Joshua Reynolds, who says: “My notion of nature comprehends not only the forms which nature produces, but also the nature and internal fabric and organisation ... of the human mind and imagination.” (Seventh Discourse.)
