Manual of Design - Compiled From the Writings and Addresses of Richard Redgrave, R. A., Surveyor of Her Majesty's Pictures, Late Inspector-General for Art, Science and Art Department #268403

I have studied to arrange and bring together like things in the order and upon the plan which my father has in most cases pursued, to avoid the repetitions which would naturally arise in such a series of documents, and to omit only such matters as had a local and temporary interest.
