6. In this view of the Nerves of Respiration, (uriginating in the Medulla Oblongata, which is an extension of the Cerebellum, (6,) or seat of Volunlary Motion, and of the Cerebrum, (a,) or seat of Rationality,) may be seen the nerve (c.) that goes to the Diaphragm (i,) and is concerned in the office of breathing, which generally acts without the aid of the Will; but yet is controllable by the Will, to a certain extent; for we may breathe fast or slov, lang or short. Next above this, is the Spinal Accessory Nerve, used in moving the breast, &c., in respiration; one of its fellow roots goes to the tongue (d,) and is concerned in mastication, swallowing, speaking, &c. [Some nerves are thrown back, the better to be seen.] Next in order is the .

From the spinal marrow, the serves arise by two sets, or bundles of roots; the front (anterior,) one serving for motion, and the back (posterior,) are the nerves of feeling, or sensibility. Now, in all voluntary actions of the body, whether reading, speaking, singing, or working, there should be a perfect harmony and co-operation of the Organic Nerves, Respiratory Nerves, and Motary Nerves; hence, the voluntary effort must be made from the abdomen, where is the great centre of Organic Nerves, in connection with those of Respiration.
