283 Brücke, Physiologie, II. p. 53. While these sheets are passing through the press, Goltz has published his second series of experiments on the brain. The following detail is a good illustration of what is said in the text: A dog deprived of a portion of both hemispheres displayed a marked imperfection in the execution of ordinary instincts. Although sight was impaired he could see, and recognize men and certain objects: the sight of a whip made him cower, but the sight of meat did not suffice to set the feeding mechanism in action. When meat was suspended above his head, the scent caused him to sniff about in search, but he failed to find it, and even when he was so placed that he could see the suspended meat, the unusual impression failed to guide him. If the meat were held towards him, or placed before him in a dish, he took it at once—this being the customary stimulation. So also, if the hand were held up, in the usual way when dogs are made to leap for food, this dog sprang vigorously up and caught the food; but he would spring up in the same way when the hand was held empty, and continue fruitlessly springing, whereas an uninjured dog ceases to spring when he sees the hand is empty.—Pflüger’s Archiv, Bd. XIV. p. 419.

286 Virchow’s Archiv, Bd. LX. pp. 130–33. Yet there are many physiologists who persist in placing the motorium commune in the corpora strata! And they place the sensorium commune in the optic thalami, although, not to mention the ambiguous evidence of Pathology, the experiments of Nothengel and Veyssière show that destruction of the thalami does not destroy sensation. See Veyssière, Recherches sur l’hémianesthésie de cause cérébrale, 1874, pp. 83, 84. I may observe, in passing, that the notion of the corpora striata being the necessary channel for volitional impulses, and the optic thalami for reflex actions, is utterly disproved by the experimental evidence recorded in the text, as well as in § 66.
