THE NERVOUS SYSTEM. Within the skull lies the brain, a mass of nervous mattersimilar to and continuous with the spinal cord. From thisbrain-matter or spinal cord, delicate threads called nervespass to every part of the body. Some idea of the natureand beauty of their arrangement may be seen in Fig. 3, p. 21. THE SPIIVAIi NERVES, Connecting with the cord, are in pairs, of which there arethirty-one. Each pair has two roots, — a motor root, aris-ing from the anterior columns of the cord, and a sensitiveroot, springing from the posterior columns. A section ofthe cord is surrounded by its sheath. The spinal nerve isformed by the union of the motor and sensitive the union, the nerve, with its motor and its sensitivefilaments, divides and subdivides as it passes on, and isdistributed to the tissues of the several organs.

These nerves, then, are undoubtedly the organs of feelingand sensation of every kind; through them the mindoperates upon the body. T
