414 BIOLOGY. 



2445. It is that which is general in the animal. 



2446. The whole animal is naught but a sense of 

 feeling. 



2447. Out of the feeling-sense all other senses must be 

 developed, just as all other systems are developed out of 

 the tegumentary formation. 



Organs of Touch. 



2448. Where, however, the skin has attained to a 

 higher grade of formation, or where it has combined 

 with higher systems, there also will the sense of feeling- 

 be supplied by the former. 



2449. The combination of the integument with the 

 osseous and muscular system, and with a nervous system 

 of its own, takes place in the limbs. Since the motor 

 members are only a liberated thorax, so no other sense 

 can belong to them but that of feeling, which the thorax 

 previously possessed. 



2450. But these sensitive organs are moved, and 

 therefore voluntary organs, digits, or former branchiae. 

 Moveable or voluntary organs of feeling are called tactile 

 organs. The feeling of the motor members is touch. 



2451. The highest feeling necessarily consists in 

 touching, because it has in that become active, while be- 

 fore it was only passive. 



2452. In the situation of the sensitive papillae, the 

 origin of the digits from respiratory organs admits of 

 being still recognized. They are arranged in spiral lines 

 upon the points of the fingers. 



2453. The sexual organs belong as tegumentary de- 

 velopments to the sense of feeling. There is no special 

 sexual sense. 



2. Intestinal Sense. 



2454. Opposite to the general feeling or the integu- 

 ment, the function of the intestine is evolved. In the 

 trunk it is simply busied with its own processes ; when 

 it first mounts or ascends into the head, it becomes sub- 

 ordinated to the nervous action.
