brain by the mind. Each may initiate action, but in all our high, characteristic activities, the agent is the mind itself. We object then to the statement given below from Spencer, and to many kindred statements, as at once unproved, improbable, and wholly destructive of the integrity of mental facts. "What is the meaning of the human brain? It is that the many established relations among its parts, stand for so many established relations among the psychical changes. Each of the constant connections among the fibres of the cerebral masses, answers to some constant connection of phenomena in the experience of the race." Principles of Psychology, Vol. I. p. 468.

The relation of the brain to the mind is a subject undergoing close inquiry and careful experiment. The conclusions already reached by Ferrier and others make it comparatively certain, that the structure of the brain and nervous system in man is one throughout of definite relations, fitted to the double work of conveying distinct impressions inward and correspondingly distinct energies outward. Indeed, if there are any well adjusted connections in these channels of communication, we may well expect them to be complete. Their value and fitness must evidently depend on this continuity. The exact cannot pass at pleasure into the vague, the well ordered into the unordered, and retain their value. While these nervous connections are relatively precise, they are by no means single, similar results may be reached in more than one way. We may figure the cerebrum as offering definite termini for definite impressions from the exterior world, and also definite starting points for reciprocal energies. Here is a result like, and yet very unlike the statements of phrenology. The nervous system, has, as an instrument, fixed relations as certainly as a type-setting machine, or an organ, though, unlike these, it conveys impressions both ways, as the receptive
