Examination of tLo spinal cord of man in reference to the connections of the cells of Clarke’s column, the inter- medio-lateral, and the solitary cells of the posterior horn, IS attended with many difficulties, which the anterior cornual cells do not offer. The latter, multipolar cells give origin to the large fibres of the anterior roots, and are con- nected with similar cells above and below, and in the opposite anterior cornu. It would seem probable that their multipolar character is associated with these connections. The other cells of the cord are, for the most part, simply bi-polar. Iheie IS good reason to believe that nerve fibres bear a relation m size to the cells in which they originate. It is also probable that a nerve cell is larger when the nerve foimed by its axis-cylinder process has a long course before It epes to Its final termination. Hence the anterior cor- ual cells of the lumbar or cervical enlargements are larger than are met with elsewhere. A fibre, however, may branch happens in the T-shaped fibre of This h' of the ganglion on the posterior root (Eanvier) This,_ however, does not apply to the fibres met with in the anterior roots, and it may be concluded that GaskelD is ' ‘Journal of Physiology,’vol. vii.
