movements of the limbs as revealed to Sight, and the sum total 

 of Kina3sthetic Impressions simultaneously received from the same 

 parts. 



This kind of education being once completed in regard to any par- 

 ticular Movements, the knowledge subsequently derivable through 

 the Kinsesthetic Centre becomes as real and as capable of passing 

 over into appropriate action as that previously coming through 

 the Visual Centre. Thereafter its impressions alone — even when 

 they very imperfectly, or not at all, rouse our Consciousness of their 

 existence — suffice to inform us (that is, suffice to excite the proper 

 Cerebral ' centres ' in ways definitely related to different positions 

 and tensions) as to the exact position of our limbs, and as to 

 the nature and degree of their Movements. It is by Kineesthetic 

 Impressions that we are afterwards continually instructed as to the 

 qualities of the Movements actually produced ; through them we 

 know whether to continue with our present mode of action, or 

 whether, the better to attain the desired end, the quality of the 

 * Volition ' should be altered. And if, during the execution of a com- 

 plex Movement, any alteration should be desired in respect to one 

 of its 'volitional ' qualities — that is, either as regards the strength, 

 the rapidity, the direction, or the continuance of one of its com- 

 ponent motions, this, " barely by a Thought or preference of the 

 Mind," can be immediately effected, though the great majority of 

 mankind would have no knowledge whatsoever of the nature and 

 degree of the individual changes brought about in the actions of 

 the different Muscles concerned. 



The mode of acquisition above indicated seems well to accord 

 with our other interests and with the daily necessities of our Life. 

 The sense of Sight greatly facilitates the process of learning, and 

 its vivid impressions speedily enable the ' sensorium ' to appreciate 

 aright the meaning of the more vague and occult impressions 

 coming to it simultaneously through the ' sense of Movement.' 

 Soon, however, the Visual Sense, which we need for so many other 

 important purposes, no longer requires to be concentrated merely on 

 the performance of Movements. Later still, our ' attention ' or 

 Consciousness becomes further freed from disturbing details con- 

 nected with Movements. The possibly conscious impressions per« 

 taining to the 'sense of Movement' at last habitually pass un- 

 heeded, and then we come to perform multitudes of daily actions 

 under the guidance of mere ' unconscious ' Kina3sthetic Impressions. 



Thus the working of the ' motor' side of our complex nervous- 

 mechanism, even when it is concerned in executing the behests oi
