446 THE SALIVARY GLANDS, BY E. F. W. PFLUGER. 



which possess granular soft protoplasm in sparing quantity, 

 contain round highly refractile nuclei, and possess numerous 

 cylindrical highly refractile processes. These are undoubtedly 

 in an early stage of development (fig. 90, c). Even if these cells 

 form a reticulum, this furnishes no evidence of their indifferent 

 nature, since all ganglion cells are beyond doubt parts of the 

 great network of animal tissue. 



Lastly, even if, looking at the great variety of multipolar cells, 

 it be admitted that we are here dealing with cells of different 

 nature and attributes, it still appears to me that we have ob- 

 tained a sufficient answer to one of the above alternatives, and 

 that the multipolar cells must be regarded as small ganglion 

 cells. 



The mode of termination of the nerves here described I 

 have termed that " effected by the means of multipolar cells," 

 an expression which is only in accordance with fact, and to 

 which, consequently, no objection can be raised. 



The remarks hitherto made upon the relation of the nervous 

 system to the salivary glands refer exclusively to the sub- 

 maxillary gland. 



At the same time I have convinced myself that the alveoli of 

 the parotid gland enter into relation with strong medullated 

 nerves in the same manner as has been just described in the case 

 of the submaxillary gland. The parotid, moreover, as well as 

 the sublingual gland possesses salivary tubes presenting similar 

 structural features. Krause has demonstrated the presence of 

 similar multipolar cells in the parotid, and I have also more 

 recently found them in the sublingual gland. If we take into 

 consideration the very similar structure that is thus exhibited by 

 these glands, and the dependence of their activity upon the 

 nervous system, we can scarcely hesitate to believe that a com- 

 plete agreement prevails also in regard to the mode of termi- 

 nation of their secretory nerves. 



As regards the sensory elements of the nervous system, W. 

 Krause* has discovered a simple kind of Pacinian corpuscle, to 

 which he has given the name of " Terminal Gland Capsules." 

 In the majority of animals, however, they are rarely present.
