The results of Vivisection have been unsatisfactory. But it has shown that slicing away the anterior and upper parts of the brain of an animal produces a state of partial stupor--a loss of its intelligence and mental characteristics, without producing any great detriment to its muscular and physiological functions; while injuries inflicted upon the basilar parts of the brain produce evident derangements of muscular action, and are more dangerous to life. Vivisection has been almost entirely fruitless for the discovery of psychic functions, but in the hands of Prof. Ferrier and the continental vivisectors it has thrown much light upon cerebral psychology, and as I shall hereafter show, has confirmed my own discoveries. Pathological Anatomy, too, has been extremely unprofitable. "The results of Pathological Anatomy (says Muller) can, however, never have more than a limited application to the physiology of the brain. We are unacquainted with the laws according to which the different parts of the organ participate in the functions of each other, and we can only, in a general way, regard as certain that organic diseases in one part of the brain may induce changes in the function of other parts; but from these facts and the results of Pathological Anatomy, we cannot always draw certain conclusions." Mr. Solly, after commenting on the general failure of Vivisection, remarks, "From pathology we might naturally expect surer evidence; but even here the physiologist who carefully examines its records is doomed to disappointment. As will be proved hereafter, no certain light has yet shone on physiology from this source." Cerebral pathology will not continue to be so barren a study when we have a true cerebral physiology to guide us. I find all pathological cases instructive as confirmations and illustrations of true cerebral science. The method of Dr. Gall--studying the growth and development of the different parts of the brain, as indicated by the cranium--is the most simple, rational and successful of all the methods adopted up to the present time. In his hands it has elicited a valuable and practical, though rude, system of phrenology. But Craniology or skull-study cannot perfect, nor can it positively demonstrate, the science.
