reason can set the body in motion by commands issued through the brain and travelling down the motor nerves, so the departmental consciousness can initiate changes and disturbances in the various nerve centres with which it is associated. This, we take it, is what happens in all cases of mental healing. The phenomenon is physical as well as psychical; it consists not merely in the inhibition of the feeling of pain, but in such a modification of the nerve tissues as removes the cause of the pain. A real cure is effected, and it is effected by the action of the residual consciousness upon that particular part of the organism.
