CHAPTER XIV
HOW WE PRODUCE COLOUR
THE SCRIBE'S NOTE ON CHAPTER FOURTEEN
Colour is merely a sensation in the brain.
What the electrons really produce are æther waves, and these give rise to the sensations of colour.
However, the electrons may claim to produce colour in the same sense as we savages produce pain in fellow-men by firing rifle-bullets at them.
The electron explains how some objects appear white, while others are red, and so forth.
