FORMING ALBUMEN, FIBRINE, CASEINE. 189 



iron is present in the blood, serving to impart to 

 it a red color, and a little silicon and potash are 

 found in the solid skeleton parts of plants and 

 animals. These kinds of molecules are scientifi- 

 cally combined together to form the mechanisms 

 of living plants, and of the animals in which finite 

 intelligences on earth for a brief time have local 

 habitations. The immediate seat of human intel- 

 ligence, the brain, according to Fremy, is composed 

 of seven parts of albumen and five of fatty matter, 

 with a little phosphorus and sulphur, and the 

 remaining seventy-five parts of water. In this 

 arrangement of molecules in cells, tubes, and con- 

 ducting nerves, constituting the brain, human 

 intelligence is enthroned, and by it receives and 

 transmits communications from and to the objects 

 of the external world. 



As each individual molecule serves as an elec- 

 trical machine for developing a peculiar reaction, 

 so each kind of groupings of molecules similarly 

 serves to develop a peculiar electro-mechanical 

 reaction, which constitutes the characteristic prop- 

 erties of various compound substances. 



The annexed table exhibits the proportionate 

 quantities of each of the four most excitable kinds 

 of elementary molecules, which are utilized as 

 food for developing plants and animals, animal 

 warmth and motive-power ; and also as fuel for 

 developing heat, light, and the motive-power of 

 steam.
