648 Dynamic Theory. 



organs above mentioned, viz. , the initial and the terminal, there must be 

 a vast number of connecting intermedial organs. The energy in its 

 passage across the brain encounters and differentiates such of these or- 

 gans as lie in its path, and perhaps is itself entirely absorbed in the 

 process. It is at least often modified and more or less deflected by its 

 reactions from such organs. 



The intermedial organs constitute the great body of the internal senses, 

 to be described further on, with the predispositions put upon them by 

 heredity or habit. And they bear the bulk of the impressions of edu- 

 cation, experience and reflection; and the reactions from them taken to- 

 gether constitute the character. These intermedial organs are usually 

 the immediate modifyers of the motor actions by directing the stimula- 

 tion upon the terminal or motor cerebral organs. The muscular ex- 

 pressions, therefore, which are set up through these last, must correspond 

 generally with the predispositions of the intermedial organs, and if we 

 can give them a proper interpretation they become an index of the 

 character. The method of reading character by observation of muscular 

 expression is common to almost all men and animals. A tree is known 

 by its fruits, and even a horse or a fish will read a man's character in 

 part by his actions. But this sort of reading requires time enough to 

 eee the actions performed. If we could see the organs of the terminal 

 class, or those from which the muscular actions are immediately stimu- 

 lated, they would show by their size the amount of work they do, and 

 consequently the relative activity of the muscl'es subject to their stimu- 

 lation and we could thus read the character upon the same general prin- 

 ciple as by watching the effects of the stimulation upon the muscles of 

 expression over a term of years. We say of a person who laughs readity 

 that he is jolly. If we do not see him laugh, but could see the cerebral 

 organ which governs the stimulations of the muscles engaged in laugh- 

 ter, we should know from their size that they were in frequent activity 

 and that the man was jolly. Furthermore, if such organ lay on the ex- 

 ternal part of the brain and underneath a thin portion of the skull, there 

 is nothing violent in the supposition that there might be a bulge or 

 prominence in the skull over that organ, which would give a skilful 

 manipulator an intimation of the relative importance and activity of 

 such organ. To this extent, then, it is reasonable to say bumpology 

 might go. Those faculties which have pronounced muscular expression 

 might be read in brain prominences provided such prominences were ac- 

 cessible, and provided further, that such expressions were exclusively 

 the result of such faculties. For example, there are cells which 

 control the muscles by which a man takes off his hat. Suppose these 

 .could be found on the external surf ace of the cerebrum ; the phrenologist
