Continuing experimentson the animals, it has been shownthat even if a portion of the brain be cutaway, it is still possible to operate on thenerve lines in the usual manner by means ofelectricity. Pushing experiment in this directionstill further it has been found thatmore serious injury permanently destroys thecentre, and entails paralysis of the musclescontrolled by it when in a healt'hy state. Inlike manner it has been proved that if thenerve itself be cut, the communication is atan end, and movement by stimulation has becomeimpossible.By perpetually occurring cases of paralysisin human experience, and careful examinationafter death of the exact situation and extentof disease in the brain, it has been shown byaccumulation of evidence, that the laws whichprovide for sensibility and for muscular activityin the history of the lower animals, do alsohold in the case of man. While the brain con-
