The following is an experiment of J. P. Brondgeest’s:--“Cut the spinal cord beneath the bulb, and lay bare the sciatic nerves on each posterior limb. Cut one of these two nerves, and suspend the creature by the head. If we then observe the situation of the two limbs, a difference is perceived, which has been shown to be invariable in sixty-two experiments. The foot of which the nerve is cut is limp and pendant; that of which the nerve is intact is slightly bent in all its articulations. M. Brondgeest made similar experiments on rabbits and birds.… If we detach by one of its extremities a muscle newly prepared on a living animal, taking care to preserve its nerve, and attach to the extremity of this muscle a certain weight, … we shall see that it will augment in weight.”--_Traité de Physiologie_, Béclard, 1862, pp. 640-41. =Brouardel, Paul.= M.D., Paris, 1865; Phys.
