“We have long been in the habit, in class demonstrations, of removing the optic lobe on one side from a pigeon.… The experiment of dividing the sympathetic in the neck, especially in rabbits, is so easily performed that the phenomena observed by Bernard and Brown-Séquard have been repeatedly verified. We have often done this in class demonstrations.” “The cerebral lobes were removed from a young pigeon in the usual way, an operation … which we practice yearly as a class demonstration.” “Our own experiments, which have been very numerous during the last fifteen years, are simply repetitions of those of Flourens, and the results have been the same without exception.” We have frequently removed both kidneys from dogs and when the operation is carefully performed the animals live from three to five days.“--Dr. Flint’s _Report to the Medical Congress_, August, 1881. “It is not desirable to administer an anæsthetic, and it is much more satisfactory to divide the nerve without etherising the animal, as the evidence of pain is an important guide in this delicate operation.”--_Text-Book_, p. 641. Speaking of an experiment by which an animal was caused to vomit from a pig’s bladder which had been substituted for a stomach, Dr. Flint says in his “_Physiology of Man_,” Vol II., p. 300:--“These experiments were made simply for class demonstrations, and have never before been published.” =Flourens, Jean Pierre Marie.= B. at Thezan (Hérault), 1794, D. at Mougeron, near Paris, 1867; M.D., Montpellier, 1813, pupil of De Candolle and Cuvier; Prof. at the Jardin des Plantes; Mem. of Inst. of France; Perpetual Sec.
