358 PHYSICAL EXPRESSION. 



nerve-mechanism is retentive, and is not very 

 changeful. 



(6) Special combinations of movements, as the 

 outcome of certain brain conditions or emotions, 

 may be demonstrated by enumeration or by the 

 graphic method. A series of movements would 

 best be demonstrated by the graphic method. 

 Thus, I think that some of the signs of general 

 brain conditions may be recorded by numbers, 

 with as much accuracy as the temperature of the 

 body, which is one sign of fever, and can be recorded 

 by the thermometer, 



(7) All those signs in an infant which show its 

 capacity for the development of mind, in as far 

 as mind is expressed in movements, might be 

 recorded by the graphic method in terms of lines, 

 and enumerated in figures corresponding to isolated 

 movements and combinations of movements. By 

 repeating the examinations at different ages and 

 under various external circumstances, expressions 

 may be obtained, in terms of lines and figures, 

 indicating the evolution of the physical indications 

 of mind. At the same time, it would be easy to 

 observe the effects of external circumstances upon 

 this evolution. 



(8) A very interesting question is to find out how 

 co-ordination of movements is brought about. A 

 co-ordinated movement is a series of movements, 

 a series of combinations of movements, and single 

 movements. A series of movements can be recorded 

 by the graphic method ; the time of each movement 

 is indicated by the tracing, and the time of the
