    ON THE CONTRACTILITY OR IRRITABILITY OF THE MUSCLES OF PARALYSED LIMBS, AND THEIR EXCITABILITY BY THE GALVANIC CURRENT, IN COMPARISON WITH THE CORRESPONDING MUSCLES OF HEALTHY LIMBS. By ROBERT BENTLEY TODD, M.D., E.R.S., FELLOW OF THE COLLEGE OF PHYSICIANS, PHYSICIAN TO KING’s COLLEGE HOSPITAL, AND PROFESSOR OF PHYSIOLOGY IN KINg’s COLLEGE, LONDON. Received June 17th—Read June 22nd, 1847. This subject has aReady been brought under the notice of the Fellows of this Society by Dr. Marshall Hall, who has put forward his views respecting it in a paper printed in the 22nd volume of the Transactions. The statements made in that paper have been repeated by its author in the article Irritability,” in the Cyclopiedia of Anatomy and Physio- logy, and subsequently in a volume of Essays very recently published.* In these various writings Dr. Marshall Hall makes a dis- tinction between the paralysis which results from lesion of the spinal cord and that produced by lesion of the brain. The dis- tinction laid down by him may be thus expressed:—In cere- bral paralysis, the irritability of the affected muscles becomes augmented : in spinal paralysis, the muscles supplied with nerves from the diseased portion of the spinal cord quickly • See also Essay on tlie True S])inal Marrow, &c., 1887, p. 102.
