SYSTEMATIC ANALYSIS OF APPARATUS. 81 



mind must have means there from which to discharge 

 an influence to act through the conducting medium 

 upon the parts that are to directly cause the motion. 



258. THE SIMPLEST FORM OF MOTORY APPARATUS 

 imaginable, would be a Ganglion to produce an influence 

 at the option or will of the mind, a nerve to conduct the 

 influence, and a part or organ to receive the influence 

 and shorten (contract) or lengthen (relax) accordingly. 



259. AN APPARATUS COMPOSED OF ONLY THREE OR- 

 GANS will seem to be too simple for the purpose of pro- 

 ducing nervous motion, when the great number and ap- 

 parently complicated motions in the Human Body are 

 considered, some of them almost infinitely delicate, as 

 in producing the shades of speech, and others as rude 

 and as strong as the grasp of a madman. 



260. Query. Is it possible that every nervous mo- 

 tion, each mental expression and the beating of the heart, 

 the winking of the eye and the inhalation of air, the 

 voice of command and the whispered lullaby, the beck- 

 oning hand and the repulsing foot, the writhings of 

 anguish and the merry laugh of joy, the ploughman's 

 labor and the boy's play, are all performed by the action 

 of an apparatus so simple as to be composed of only 

 three kinds of organs ? 



261. IN FACT, ONLY GANGLIA, J^ERVES, AND MlJSCLES 



are necessary for constituting a motory apparatus, and 

 performing all the varied nervous motions in the Human 

 Body not only, but also in the bodies of all animals ; 

 the swiftness of the bird, the strength of the beast, the 

 wriggling of the serpent, and the hum of the insect, are 

 due to the same three kinds of organs of a motory ap- 

 paratus. 



262. Inf. THE MOST PERFECT AND WONDERFUL RE- 

 SULTS are produced in the Divine architecture of the 

 Human Body in the simplest manner. 



263. THE REASONS WHY THE THREE KINDS OF Mo- 



258. What is ? 259. What will seem ? 260. What is ? 261. What neces- 

 sary for motion ? 252. How arc produced ? 263. What are ?
