20 THE TONER LECTURES. 



brains, it is clear that we ought to develop both of them, and I 

 can say, at any rate, as much as this, there is a chance — I 

 would not say more, but at least I can say there is a chance — 

 that, if we develop the movements of the two sides of the bodj', 

 the two arms and the two legs, one just as much as the other, 

 there is a probability that the two sides of the brain then will 

 be developed, as regards the mental faculties, one as much as 

 the other. 



The facts that I have brought forward, the last especially — 

 what I have called the four points of importance, and particu- 

 larly the first three, show that there is a connection between 

 the development of the brain as regards the mental faculties, 

 and the development of the brain as regards leading movements 

 in one side of the body. There is a great probability, therefore, 

 that, if we give a good deal of attention, or, better, as much 

 attention to the left side of our body as we give to the right, 

 there is a great chance that we would have two brains, as re- 

 gards mental functions, instead of one, as we have now. There 

 is no doubt that we can .improve the two sides of the body con- 

 stantl3\ The facts I have mentioned as regards those children 

 having atrophy on the left side of the body, do not leave room 

 to doubt. It is clear we can develop the left side so as to make 

 it exercise all the functions which exist in most of us in the left 

 side of the brain, and, if so in cases of atrophy on one side of 

 the brain, why not so in cases in which we have two brains ? I 

 think, therefore, the important point should be to try to make 

 every child, as early as possible, exercise the two sides of the 

 body equally — to make use of them alternately. One day or 

 one week it would be one arm which would be employed for 

 certain things, such as writing, cutting meat, or putting a fork 

 or spoon in the mouth, or in any of the other various duties in 

 which both the hands and the feet are employed. In this way 

 it would be very easy indeed to obtain a great deal, if not all 

 the undeveloped power possible to the individual. "We know
