From the spinal marrow, the nerves 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.
