56 THE INTERNAL SECRETIONS 1920 



well-being and efficiency are impaired until that bal- 

 ance is restored. This is true whether the balance be- 

 tween the endocrine organs themselves is at fault or 

 whether the balance between these organs and the rest 

 of the body is impaired. 



The imbalance manifests itself in certain physical 

 or mental symptoms, and often both. We cannot con- 

 sider balance without thinking of the relationship of 

 the endocrine organs as a whole.
