"When we reach the luminiferous track on the ninths, in the triple subdivision, we have proof that the infinite stream, from that unexplored region where all sympathetic streams emanate, is triune in its character, having the dominant as the sympathetic leader, to which the remainder of the celestial thirds are subservient; the cerebellum being the dominant, and the triplets (gravital, electric, and magnetic) following in its train." [Newton of the Mind]
