6. In this view of the Nerves of Respiration, (originating in the Medulla Oblongata, which is an extension of the Cerebellum, (6,) or seat of Voluntary Motion, and of the Cerebrum, (a) or seat of Rationality,) may be seen the nerve (c) that goes to the Diaphragm (,) and is concerned in the office of breathing, which generally acts without the aid of the Will; but yet is controllable by the Will, 10 a certain extent; for we may breathe fast or slow, long 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 7. Here is an excellent representation of the pneumosgastric, or lungs-and-stomach nerve (f, Nerves of Voluntary Motion, and of Sense, which, g, h.) which sends a branch to the meat-pipe, la, with the nerves of Organic Life, and the Respirarynx and wind-pipe, (e) also to the cardiac, or tory Nerves, constitute the inmosis of the body; heart plexus, just above, and a little at the right also, a posterior, or back view, of the two brains, 0; (g); a recurrent branch goes to the larynx, &c.; which is the seat of the Mind, the constitaenis or olner branches go to the face, to exhibit the feelings. which, are Will and Understanding. The letter All interweave, and bring the vocal organs into c, indicates the cerebrum, or large brain, where mportant relations with the heart and lungs, with the Understanding, Rationality, or thought is loeelings and thoughts; while the main body goes cated; and cv, the cerebellum, or Litle brain, o the stomach, avui unes with the great centre I under, and adjoining the cerebrum, where the Rorizontal black line is: here is the seat of the 9. We now descend to the hard parte of the Will, Affections, Passions or Emotions; also the body, which have the least of life in them. This seat of the Motive power of the body; and from is a very correct representation of the Osseous these proceed the spinal marrow, (me,) enveloped system, or the bony paris which may be aptly in three different membranes, lying in the hollow of the back bone, and branching off by thirty pairs of spinal nerves into a great many ramifications over every part of the body; pó, the brachial plexus, a reunion or assemblage of the different nerves distributed to the arms, or upper extremities; und ps, the plexus, or folds of nerves, that form the great sciatic nerves, descending to the legs, or lower extremities. From the spinal marrow, the nerves arise by two sets, or bundles of rools; the front (anterior,) one serving for motion, and the lack (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 pertect harmony and co-operation of the Organic Nerves, Respiratory Nerves, and Moiary Nerves; hence, the voluntary effort must be made from the abdomen, where ks the great centre of Organic Nerves, in connection with those of Respiration.
