=Chauveau, A.=, 22, Quai des Brotteaux, Lyons. Chef des Travaux d’Anatomie et de physiologie à l’école Vétérinaire de Lyons. Author of “De l’excitabilité de la moëlle épinière;” “Du nerf pneumogastrique,” &c. Describes his own experiments in Brown-Séquard’s _Journal de Physiologie_. The object was “to ascertain the excitability of the spinal marrow, and the convulsions and pain produced by that excitability.” His studies were made almost exclusively on horses and asses, who “lend themselves marvellously thereto by the large volume of their spinal marrow,” and he “consecrated 80 subjects to his purpose.” “The animal is fixed on a table; an incision is made on its back of from thirty to thirty-five centimetres; the vertebræ are opened with the help of chisel, mallet, and pincers, and the spinal marrow exposed.” No mention of anæsthetics. Case 7. A vigorous mule. “When one pricks the marrow near the line of emergence of the sensitive nerves, the animal manifests the most violent pain.… Case 10. A small ass very thin, pricked on the line of emergence--_douleur intense_. Case 20. Old white horse lying on the litter, unable to rise, but nevertheless very sensitive. At whatever point I scratch the posterior cord, I provoke signs of the most violent suffering.”--_Journal de Physiologie_, Vol. IV., No. XIII., p. 48. =Cheyne, Wm.
