Note 38 — Chapter IV · THE PROPERTIES AND FUNCTIONS.
Reading edition
Vulpian, Leçons sur la Physiologie du Système Nerveux, 1866, p. 581. In a work just published I find M. Luys hesitating at the consistent application of this law. After pointing out the identity of the tissue in cerebrum and spinal cord, he is only prepared to say that we cannot deny that there is no impossibility in admitting physiological equivalence where there is morphological equivalence.—Luys, Actions Reflexes du Cerveau, 1874, p. 14.
