THE WEIGHT OF THOUGHT.

Professor Mosso, an Italian physiologist of repute, has demonstrated by experiment that thinking causes a rush of blood to the brain, which varies with the nature of the thought. This has long been believed by students and literary men, but Mosso proved it by balancing the living subject in a horizontal position so delicately that when he began to think the accession of blood to his head turned the scale. When the subject was asleep, the thoughts or visions which came to him in dreams were sufficient to sink his head below his feet; and the same thing took place when the sleeper was disturbed by a slight sound or touch, Signor Mosso’s balance even allowed him to tell when his friend, the subject, was reading Italian and when Greek ; the greater mental exertion required in the latter case producing a greater flow of blood to the head.
