    the Motor Centres, concerned with Speech-movements and with Writing-movements, in the Corpus Striatum. The relation existing between the Auditory and Visual Word-Centres and the parts of the Kinsesthetic Word- Centres to which impressions derived from Speech-move- ments and Writing-movements respectively proceed, are confessedly uncertain. There is reason to believe, how- ever, that the incitations which evoke Speech start primarily from the Auditory Word-Centre, and then pass through the corresponding Kinsesthetic Word-Centre, so as to rouse it into conjoint and practically simultaneous activity. Similarly, there is reason to believe that the incitations which evoke Writing-movements start primarily from the Visual Word-Centres, and thence pass through the related parts of the Kinaesthetic Word-Centres. It is clear, therefore, that destruction of the Auditory and of the Visual Word-Centres would cause inability to Speak and inability to Write. These disabilities would, however, be associated with such defects as have been considered under the head of Amnesia—viz., inability to comprehend Speech and Writing, together with inability to revive Auditory and Visual ideas of Words. What we are specially concerned with in the present section are the results that follow upon damage to the outgoing fibres leading from the left Auditory and Visual through the Kinaesthetic Word-Centres, to the great Motor Ganglion beneath—viz., the Corpus Striatum. It would seem that these two sets of outgoing channels are, at all events in some parts of their course, situated moderately close together, so that they may be destroyed simultaneously by some small lesion, and that too without the implication of outgoing fibres for limb-movements— and consequently without the association of a right-sided paralysis.
