SYSTEMATIC ANALYSIS OF APPARATUS. 125 



469. THE TRUE ELIMINATING ORGANS ARE the Kid- 

 neys and the Perspiratory Glands ; the Digestory Canal 

 (and its appendages, the Liver particularly), Liver, and 

 Lungs, Eliminating in common with other functions. 



470. THE ELIMINATIONS may be correspondingly 

 classed : Renal (of the Kidneys), Perspiration, Intestinal, 

 Hepatic (of the Liver), Pulmonary (of the Lung).

Modificatory Organs. 



471. EVERY ORGAN OF THE BODY THUS FAR CONSID- 

 ERED, it is evident, is constantly modifying the Blood by 

 what it takes from or adds to it. 



472. IT WOULD NATURALLY BE SUPPOSED that SO 



many substances thrown into the current of the Blood, 

 by the Lungs from the Air, by the Digestory Canal from 

 the Food, and by the action of all the organs of the 

 Body, together with what would be left by the organs 

 forming fluids for various purposes, would require some 

 modifying influences, to combine and assort the whole in 

 such a way as to render it most serviceable, or to facili- 

 tate its exit from the Body. 



473. WHAT COULD BE BETTER ADAPTED to the pur- 

 pose of modifying the Blood than to have an immense 

 number of organs, if they may be so called^ so small that 

 they could circulate everywhere with and in the Blood ?
