Everywhere, as we are well aware, the lines of active phyletic development grow warm with consciousness as they approach the summit; but in one clearly - marked region at the centre of the kingdom of mammals, where the most powerful brains ever fashioned by nature are to be found, the lines glow red - hot; and already at the heart of this region there burns a point of incandescence.
