1130. THE ELIMINATION OF A CER- 

 TAIN QUANTITY OF WATER WOuld be * 



necessary to dissolve and float away the solid elimina- 

 tions, but the removal of water in large quantities would 

 rapidly diminish the entire quantity of Blood circula- 

 ting in the Body, though not the heat-producing part ; 

 that would, of course, pass through its rounds, and pro- 

 duce heat so much the more rapidly. The kidneys, 

 therefore, assist in regulating the heat of the body.

 into the stomach will MANIFEST THEIR ACTION THROUGH THE KIDNEYS, has

 the two ? There is none : the ordinary circulation soon subjects all the 

 Blood to the action of these organs, and it shows the rapidity of the 

 circulation.
