“M. Vulpian has recently made a large number of experiments to ascertain the degree and character of the mechanical excitability of the grey cortex of the brain. In mammals, dog, cat, and rabbit, in the normal condition, he could never produce in this way the slightest movement either in the limbs of the opposite side, or in those of the same side. The mechanical stimulation was produced by rubbing the surface of the cortex with a small sponge, or a fragment of amadou, or with the points of dissection forceps.… If therefore movement resulted from such stimulation in the experiments of Couty, the effect must have been purely accidental or the consequence of some experimental error. The results were also negative when Vulpian repeated the experiments after having produced inflammation of the surface of the sigmoid gyrus by tincture of cantharides, by essence of mustard or by nicotine.”--_Lancet_, Sept. 16, 1882, p. 453. “I have made the section of the facial nerve at its entrance into the internal auditory meatus, in several dogs, … in other dogs I succeeded in dividing the facial nerve near its real origin, below the floor of the fourth ventricle. The results were absolutely identical … I had to undertake other experiments to find out what would be the effect of the inter cranian section of the trigeminal nerve on the chorda tympani. These experiments were made on rabbits. Although numerous, they gave but few significant results, because several of the animals did not live long enough after the operation for the divided nerves to show any very decided changes; or else because in several of them, the section of the nerve was far from being complete.”--Acad. des Sciences, April, 1878.--_Archives Gen. de Méd._, 1878, p. 751. =Wagner, Rudolf.= B. at Bayreuth, 1805.
