Heat. 



2564. The chief function of the cell-formation is the 

 process of heat. The cell-process and heat-process are 

 one in kind. Heat is the product of the process of con- 

 densation and rarefaction, and thus of the nutrition and 

 evaporation, both of which happen in the cells, or, if we 

 please, in the capillary vessels. 



2565. In the skin the process of temperature is indi- 

 vidualized. 



2566. All temperature depends upon the process of 

 condensation and rarefaction. At one time it is the 

 nerves, at another the vessels, anon, external influences, 

 which alter or modify it. Animal heat, like the cosmic 

 heat, has been produced by change of the fixation. This 

 change, however, takes place principally in the nutrition 

 and evaporation. 



2567. The fat is the " residuum" or the antagonism of 

 the process of evaporation or water-formation. It is 

 therefore deposited everywhere on the water-organs, 

 beneath the integument, along the intestine and the 

 vessels, around the kidneys, and so on. 



2568. It is, like the adipocire, a product of the aque- 

 ous decomposition. On this account it is subservient to 

 the process of temperature. It is the only isolator of 

 heat, while all other animal bodies are conductors. 



II. Functions of the Systems. 



2569. The functions do not concern the whole body, 

 but only its principal parts. 



a. VEGETABLE FUNCTIONS. 



2570. The vegetative functions are matter-changing 

 processes, which, consequently, correspond directly to 

 the chemical processes, or are rather of one kind with 

 these, but altered by organic elemental bodies.
