You never meet with quadrupeds going up and down walls; you must not have quadrupeds represented upon walls. You must use,' said the gentleman, 'for all these purposes, combinations and modifications (in primary colours) of mathematical figures which are susceptible of proof and demonstration. This is the new discovery. This is fact. This is taste.'"
