mcnt, and {b) a mechanical dialysis ol' water and crystalloids in 

 solution through the capsule under sufRcient pressure to wash the 

 actively secreted material through the collecting tubule and on 

 towards the pelvis of the kidney. 



Other Glands of Elimination. 



Of the physics of the other detoxifying glands, little or nothing 

 is known. The largest of these is the liver, but beyond the 

 isolation of enzymes, the physico-chemical mechanism has not 

 been to any great extent investigated. 



The intestine. Much waste matter is excreted by the large 

 intestine and here the physico-chemical mechanism is more clearly 

 indicated (see Chap. XXVIII.). 



Skin glands — sweat excretion will be considered under regula- 

 tion of temperature (Chap. XXXII.), and elimination by the lungs 

 under Transport (Chap. XXIV.).
