402 THE SOCIAL ORGANISM. 



besides coming gradually to consist of better ingredients, 

 also grows more complex. An increase in the number of 

 the unlike organs which add to the blood their waste mat- 

 ters, and demand from it the different materials they sev- 

 erally need, imj^lies a blood more heterogeneous in compo- 

 sition — an a. 2^io7'i conclusion which, according to Dr. 

 Williams, is inductively confirmed by examination of the 

 blood throughout the various grades of the animal king- 

 dom. And similarly, it is manifest that as fast as the 

 division of labour among the classes of a community, 

 becomes greater, there must be an increasing heteroge- 

 neity in the currents of merchandise flowing throughout 

 that community. 



The circulating mass of nutritive materials in individual 

 organisms and in social organisms, becoming alike better in 

 the quality of its ingredients and more heterogeneous in 

 composition, as the type of structure becomes higher; 

 eventually has added to it in both cases another element, 

 which is not itself nutritive, but facilitates the process of 

 nutrition. TVe refer, in the case of the individual organ- 

 ism, to the blood-discs ; and in the case of the social or- 

 ganism, to money. This analogy has been observed by 

 Liebig, who in his " Familiar Letters on Chemistry," 

 says: 



" Silver and gold have to perform in the organization of the 

 State, the same function as the blood corpuscles in the human 

 organization. " As these round discs, without themselves taking an 

 immediate share in the nutritive process, are the medium, the 

 e-sential condition of the change of matter, of the production of 

 the heat, and of the force by which the temperature of the body 

 is kept up and the motions of the blood and all the juices are de- 

 termined, so has gold become the medium of all activity in the life 

 of the State." 



And blood-corpuscles being like money in their func- 

 tions, and in the fact that they are not consumed in nutri-
