[262] Landry, Traité des Paralysies, 1859, maintains that the cord is a centre of sensation, and that there is in it a faculty analogous to the perception and judgment of the brain. Compare pp. 163 et sq. and 305. He also cites an essay by Dr. Paton of Edinburgh (Edinburgh Medical Journal, 1846), in which the sensational and volitional claims of the spinal cord are advanced.

[266] “Il y a donc une mémoire par le cerveau et une mémoire par l’automate. Tous les organes ont une mémoire propre, c’est à dire une tendance à reproduire les séries d’actes qu’ils ont plusieurs fois executés.”—Gratiolet, Anat. du Système Nerveux, 1857, p. 464.

[267] To obviate misunderstanding let me say that, unless the contrary is specified, I use the term Brain throughout this argument as equivalent to the cerebral hemispheres, because it is in these that sensation, volition, and consciousness are localized by the generality of writers, many of whom, indeed, regard the cells of the gray matter of the convolutions as the exclusive seat of these phenomena, dividing these cells into sensational, emotional, and intellectual. There are physiologists who extend sensation to the cerebral ganglia and gray masses of the medulla oblongata; but the medulla spinalis is so clearly continuous with the medulla oblongata that there is a glaring inconsistency in excluding sensation from the one if it is accorded to the other; and the grounds on which sensitive phenomena are admitted in the absence of the hemispheres, force us to admit analogous phenomena in the absence of the ganglia and medulla oblongata: in each case the phenomena are less complex and varied as the mechanisms become less complex.
