    hemiansesthesia of the opposite side of the body, frequently- associated, temporarily however, with some degree of motor paralysis; whereas when the anterior part (two-thirds) of the internal capsule (fig. 53 [a;])—that part lying between the caudate and lenticular nuclei of the corpus striatum—is divided, motor paralysis, unaccompanied by sensory paralysis, or if so, functional and fleeting, is the constant result. The facts of human pathology are no less precise. Motor hemiplegia is invariably the result of destructive lesion of the anterior two-thirds of the internal capsule, which may be accompanied temporarily by hemiansesthesia, if the lesion be such as to cause pressure, or functional disturbance of the posterior third. And we have now a tolerably large body of evidence to show that destructive lesions limited to the poste- rior third of the internal capsule cause hemiansesthesia on the opposite side of the body. The first observations relative to this localisation were made by Tiirck* in 1859, and since then, Charcot, Magnau, Bourne- ville, Eendu, Eaymond, Pierret, Decaudin, Pitres, Boyer, &c., by their observations and researches, have established the pathology and symptomatology of this affection in a manner which leaves little to be desired.
