2404. The movements of the facial muscles corre- 

 spond to those of the limb-muscles. Upon this depends 

 the interpretation of dumb-show, or the art of physi- 

 ognomy. 



3. Nervous Organs. 



2405. Nervous organs are liberations of individual 

 parts of the nervous system, and their endowment with a 

 peculiar function or sensation. 



2406. The liberations of the nerves are combinations 

 with the other anatomical systems at the spot where they 

 have attained their highest evolution. 



2407. Each system, however, has its peculiar process. 

 Through the reception or adoption of the systems into 

 the nervous system, a peculiar sensation must therefore 

 originate. 



2408. Peculiar sensations are sensations of sense. 



2409. The combinations of the anatomical systems 

 with the nervous system, whereby the former have been 

 subordinated to the latter, are consequently sensorial 

 organs, or organs of sense. 



2410. In the sensorial organs the processes of the 

 several systems attain unto sensation. They are brains 

 of the anatomical systems. 



2411. There are as many senses as there are different 

 anatomical systems, and consequently senses belonging 

 to vegetative and animal life. 



2412. The number of vegetative systems is 3 ; the 

 vascular, intestinal, and pulmonary system. 



2413. The most complete combination of the vascular 

 with the nervous system is the integument constituting 

 the tegumentary sense, or sense of feeling. 



2414. The most complete combination of the intes- 

 tinal system with the nerves is the tongue intestinal or 

 gustatory sense. 



2415. The most complete combination of the lungs 

 with the nerves is the nose pulmonary or olfactory 

 sense.
