Christopher Dresser, Jones's best known protégé, contributed one of the plates in this final chapter, and he was concurrently presenting theories on natural-form ornament in his famous botanical lectures at the Government School of Design in the mid-1850s. This last chapter raises some critics about the inability to produce new ornamental design since repetition is a common factor among nature, and Jones describes this as "going back to nature like the ancients did" but his own response to this issue evolves around the fact that nature has a great variety of line and form, and is based in geometry which gives an enormous amount of freedom to the designer to follow and idealize the form of nature as a basic element while creating something that society has never seen before.
