In surveying the relations of the parts, it is useful to begin with the spinal marrow. 7 ee Fig. 4. AB the spinal marrow seen in front; the division into lateral por- tions appearing at the line AB. The nervous cord © arises from the posterior lateral division, and communicates sensi- bility to the parts on which it is ramified. The swelling D is its ganglion. The nervous cord E arises from the anterior lateral division, and gives motion. It has no ganglion. These two cords combine at F, and proceed under one sheath to their destinations in the muscles and skin. In 1810, Drs Gall and Spurzheim represented the spinal marrow as consisting of a tract for motion, and one for sensation ;* and in 1818, Dr Spurzheim pub- lish@l strong reasons for the inference that certain of the Nerves proceeding from it perform the functions of motion, while others communicate sensation.j Several years afterwards, Sir Charles Bell described it as con- sisting of two halves, a right and left, extending its whole length. According to his first view, he described *«Anatomie et Physiologie, &c. p. 67, 4to. Paris, 1810. + Observations sur la Folie, par G. Spurzheim, pp. 26, 27. Paris, 1818.
