158 DETAILED SYNTHESIS. 



50. THE SECOND GROUP OF THREE ELEMENTS is 



MUCH THE MOST IMPORTANT IN THE BODY, since the 



manifestation of the nervous and muscular powers is 

 dependent on them. 



51. THE ELEMENTS OF THE THIRD GIJOUP are chiefly 

 useful in giving hardness to parts ; they serve admira- 

 bly in the framework. 



52. THE ELEMENTS OF THE FOURTH GROUP are 

 chiefly useful in forming the fluids of the Body. 



53. IRON, though an essential Element, does not, 

 strictly speaking, constitute any part of any tissue or 

 fluid, being part of the contents of the Blood-cells, 4 ect. 



54. ANOTHER IMPORTANT FACT is SUGGESTED by a 

 review of the third and fourth groups. Their compounds 

 in the Body are merely chemical compounds, requiring 

 to produce them no higher order of influence than that 

 which is chemical or terrestrial. 



55. THE ELEMENTS OF THE FIRST TWO GROUPS, HOW- 

 EVER, enter into compounds that cannot be produced 

 except under vital influences. 



56. THE REALLY ACTIVE VITAL PROPERTIES OR CHAR- 

 ACTERISTICS are dependent therefore upon not more than 

 the small number of the six Elements of the first two 

 groups, combined and acting under appropriate influ- 

 ences. 



SECTION II. 



Proximate or Organic Elements or Principles. 



57. THE CHEMICAL ELEMENTS MAY COMBINE, by vir- 

 tue of their own nature, or under the influence of the 

 sun's rays, or that of electricity ; but they will produce 

 merely chemical compounds, which are very different 

 from, very far short of, vital or organic compounds.
