INTERRELATIONS AMONG COMPONENTS 421 



Observation of uniformities indicates, on the contrary, that corre- 

 lated happenings are found in most instances where they have 

 been looked for. That realization is altering the course of physio- 

 logical science. 



I conclude that where recovery and constancy of a component 

 occur, there are interrelations with other components. The equili- 

 brated organism is probably one whose n components are all asso- 

 ciated in such a way that loadings of even a considerable number 

 mil not destroy the ''memory" of that net state of the organism, 

 to which all properties trend when recoveries intervene. 



I conclude that any two or more simultaneous changes in com- 

 ponents, when correlated, show evidence of inherent interrelations. 

 Examples such as water content and heat content, or various 

 properties in physical exercise, furnish coefficients and ratios of 

 preferential change. Diagrams that correlate several components, 

 and resultants that combine components, are of practical use in 

 dealing with numbers of physiological variables. All those vari- 

 ables enter into one general account of the pattern of the organism 

 and the means by which its properties are fixed.
