chance to meet the eye ; but only in accordance with the 

 rigid prescripts of the animal body's genesis. 



3074. The animal body separates into two series of 

 organs, which, corresponding with, pursue a proximal 

 course in relation to, each' other ; into the Anatomical 

 systems and the Sensorial organs, unto which the sexual 

 parts appertain. 



3075. The number of the sensorial organs is 5, and 

 they thus stand according to their genetic development 

 one above the other : 



Tactile sense or Skin. 

 Gustatory sense or Tongue. 

 Olfactory sense or Nose. 

 Auditory sense or Ear. 

 Optical sense or Eye. 



3076. In animals, which are characterized by the 

 sense of feeling or touch, the other sensorial organs must 

 be either still wanting, or if present but imperfectly con- 

 ditioned, i. e. not constituted like those of man, who is 

 the type, pattern, or paragon for every formation. 



3077. Their sensations are limited to those of general 

 touch or feeling, and of those derived through the medium 

 of the other senses we meet with but feeble mani- 

 festations. 



3078. Their body itself will only be a tegmnentary 

 body, with the organs subordinated to the integument, 

 namely, the viscera. They are therefore devoid of a true 

 tongue, of a nose, and of ears and eyes consummated 

 after the fashion of these organs in man ; they are devoid 

 of an osseous, muscular, and myelonal (spinal chord) 

 system, and therefore of the nose " in toto," as being the 

 anterior extremity of the myelon. 



3079. Such are what have been called the Invertebrate 

 animals, which are consequently, in accordance with 

 their physiological signification, Splanchnic ^Tegmnentary 

 animals. 



3080. The tongue exhibits for the first time in Fishes 

 a resemblance to the human structure, while their nose, 

 ears, and eyes have not yet attained the latter grade of
