ever, in which there is mixed physical form, there is also 

 disharmonious relationship between the bodily organs and 

 the reaction systems. For example, one system may be easily 

 excited, yet others may be extremely difficult to excite. The 

 animal may be overly disturbed in situations involving pain, 

 yet entirely undisturbed in another situation. Again the 

 muscular systems of the limbs may be well developed, yet 

 action limited because of a low energy factor. The factors 

 which influence behavior become mixed and varied, just as 

 do those which determine physical form. In the mixed types,

the harmonious relationship found within each pure be- 

 havioral type is broken up, and the result is a disharmony 

 among the systems. We have diagrammed the variations 

 found within two systems in text-figure 113. A diagram of 

 the constitution is given in text-figure 114. In this case, each 

 vertical plane erected on the circular plane and represented 

 by abo; cdo; etc. indicates reaction systems and bodily 

 process involved in activity. These are not given as the total 

 picture, but to suggest the relationship of the various or- 

 ganismal parts in the pure and mixed types. Points on the 

 line ao of plane abo represent the differences in degree of 

 excitability of the salivary reaction systems and is similar
