SYSTEMATIC ANALYSIS OF APPARATUS. 71 



196. THE APPARATUS OF SMELL is double, right and 

 left, and composed, acted upon, and acts, as follows : 



Apparatus of Smell, 

 Three kinds of organs. 



Objects, Air, Nose, Nerves, Ganglia, Mind. 

 Cause. 34 5 Sensations. 



FIG. 75.

Fig. 75 represents a section of the nose near its partition, toward which 

 the observer is supposed to look. The section is carried back into the 

 cranium, and down into the mouth and throat. I is the Ganglion of 

 smell, just above the roof of the nose, on which it rests, and through nu- 

 merous holes in which the nerves of smell, 1, extend ; 2 and 3 are divisions 

 of nerves, one twig of 3 extending through an opening in the bony roof 

 of the mouth to the skin lining it ; u is the uvula, or tip of the hanging 

 palate. The white line from it, up to 3, shows the termination of the par- 

 tition, behind which the eye can look into the other nostril, and see x, the 

 opening into the Eustachian tube, leading to the middle ear. (See Fig. 73.) 



ORGANS OF APPARATUS OF TASTE. 



19Y. SAVORY PROPERTIES EXIST in the minute parti- 

 cles of certain objects that must be dissolved for the ex- 

 hibition of their savors, and applied to nerves, when each 

 one will produce its appropriate sensation. 



198. To DISTINGUISH SAVORS, therefore, and learn

 Recording to the cut? 197. How do ? 198. What is necessary ?
