DUCTLESS GLANDS- — TAYLOR 713 



in water-tight compartments. It is, however, at the present time 

 impossible to do otherwise. 



We should look upon the secretions of the ductless glands rather, 

 I think, as forming with the blood a suitable environment, an appro- 

 priate fluid medium to bathe the cells of the tissues. When all secre- 

 tions are present in their correct proportions, the cells are healthy, 

 they flourish and grow normally. If, on the other hand, one or other 

 constituent of this nicely balanced mixture be present in reduced or 

 excessive proportion, the environment becomes unsuitable and the cells 

 suffer. Their development along the particular paths which heredi- 

 tary impulses direct them is thwarted, and abnormalities result. 



In order that there shall be physiological harmony, each endocrine 

 gland must play its part in tune with its fellows.
