can be therefore only 2 animal senses. The osseo- 

 muscular or motor sense is the ear. If the nervous 

 system becomes wholly self- substantial, the nervous 

 sense thus originates, or the eye, in which the brain itself 

 has been planted outwardly, and acts independently of 

 all other systems. 



2077. The vessels form the general system, and there- 

 fore the tegumentary sense surrounds the whole body. 

 Its brain is the spinal cord. 



2078. The four remaining senses are perfections of 

 individual systems at their perfect extremity, and thus in 

 the proximity of the mouth and the brain. They to- 

 gether form the head. The jaws and the tongue obtain 

 their nerves from the medulla oblongata, and this is 

 therefore the brain of the gustatory sense. The brain 

 for the nose is the gray cerebral substance, because the 

 olfactory nerves are its elongations. The ears obtain 

 their nerves from the cerebellum, which is consequently 

 the auditory brain. The eyes are developments of the 

 great brain or cerebrum optic brain. Such is the 

 rationale and signification of the divisions of the brain. 



2. OSSEOUS SYSTEM. 



2079. The nervous mass consists of indifferent, de- 

 oxydized blood-globules. If these be peroxydized, then 

 the highest oxyd of the planet is deposited in them, 

 namely, the earth, and that indeed which was the last 

 remnant in the order of their production, or the calca- 

 reous earth. 



2080. Vesicles or cells replete with calcareous earth 

 are globes. The osseous texture consists therefore of 

 globes ; is only a dense cellular tissue, and thus ranks 

 nearest to the vegetable structure. The basis of the 

 bones is at first a cellular gelatine, which, with increased 

 oxydation, is converted into cartilage. Finally, calcareous 

 earth is deposited in this cartilage. 



2081. In the lower organized animals, who breathe 

 for the most part by means of branchiae, the acid 

 combined with the calcareous earth is an inorganic, or 

 the carbonic acid, i. e. oxygen combdn^d_with,cai'bon, or
