6. In this view of the Nerves of Respiration, (ur.ginating 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, to & certain extent; for we may breathe fast or slow, long or short. Next above this, is the Spinal Aceessory Nerve, used in moving the breast, &c., in respiration; one of its fellow roots goes to the tongue (d,) and is concerned in masucation, swallowing, speaking, &c. (Some nerves are thrown back, the better to be seen.) Next in order is the 7. Here is an excellent representation or the pneuinosgastric, or lungs-and-stomach nerve (f, Nerves of Voluntary Motion, and of Sense, which, 8, h,) which sends a branch to the meat-pipe, la- with the nerves of Organic Life, and the Respira. rynx and wind-pipe, (,) a.so 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, of (g); a recurrent branch goes to the larynx, &c.; which is the seat of the Mind, the consutuents of other branches go to the face to exhibit the feelings. which, are Will and Understanding.

We now descend to the hard parts 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 parts 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; pb, the brachial plexus, a reunion or assemblage of the different nerves distributed to the arms, or upper extremities; and 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 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 ce-operation of the Organic Nerves, Respiratory Nerves, and Motary Nerves; hence, the volunsary effort must be made from the abdomen, where is the great centre of Organic Nerves, in connection with those of Respiration.
