Awaking. 



2766. The awaking takes place of itself through the 

 origination of a new polarity in the brain during the 

 afflux of arterial blood, whereupon the dreams follow 

 which precede the act of waking. During sleep the 

 plant continues to act, the unloaded cortical substance 

 becomes again oxydized and charged; tension arises 

 between it and the medulla, and with this come the 

 dreams. This encephalic polarity is imparted to the sensi- 

 tive and motor nerves, and the organs open. If external 

 stimuli are superadded, all this happens somewhat earlier. 

 The act of awaking is invariably, however, a restoration 

 effected, or brought about, by the plant, and especially 

 by the circulation. 



2767. Man would therefore wake up had there also 

 been no world of the senses; but then he would not 

 continue awake, but at once relapse into slumber, and 

 sleep the eternal death. 



III. Functions of the Organs. 



2768. The functions of the organs are the functions 

 of the system associated or combined, just as the organs 

 are but ultimate evolutions of the systems existing 

 under similar relations. The organic functions are al- 

 ways therefore in a state of concatenation with other 

 systems, and there can be no organ which acts in an 

 isolated manner. 



'2769. By this character a new field for sympathy has 

 been opened. All the organs operate through sympathy. 

 Sympathy is therefore the result of parallel systems, or 

 also of antagonisms between the factors of a single sys-
