304 THE BIOCOSMOS PARTICULARIZED. 



implicitly the whole of them. The immediate 

 material taken is not entirely used ; it is ana- 

 lyzed, separated into the useful and useless, 

 the latter being finally thrown off as waste. 



First in order comes the Digestive System 

 in its entirety, which embraces a flexible line 

 of organs strung along and connected with 

 the alimentary canal, through which the food 

 passes from stage to stage undergoing many 

 changes, as if in a chemical laboratory. The 

 mouth starts with the first act of division 

 which the teeth continue, till mingled with 

 saliva the first pulp is formed and driven 

 down the oesophagus. In the stomach the 

 chyme is prepared by additional processes, 

 and then follows the chyle, a milky mass 

 which the intestinal absorbents separate, tak- 

 ing up the nutritious part and passing it into 

 the blood, while the non-nutritious part is 

 rejected. Physiologists say that the proteids 

 and sugars (carbo-hydrates) are stored first 

 in the liver whose automatic action turns them 

 over to the blood gradually, as they may be 

 needed; while the food-fats pass by their own 

 line into the blood. At any rate the end of the 

 Digestive System is attained when the prod- 

 uct of all its manifold organs is turned into 

 the circulation. 



The next fact, accordingly, is the distribu- 

 tion of the digested aliment to the every point
