of preparation, on account of the fluidity of the medullated 

 fibres. 



II. ON THE MODE OF NERVE TERMINATION EFFECTED BY 



MULTIPOLAR CELLS. I have elsewhere described small pale cells 

 (fig. 89) possessing numerous processes adherent to the alveoli, 

 and for the most part smaller than the salivary cells. I re- 

 gard these as nerve cells, and consider them as entering into 

 communication, not only with the salivary cells, but also with 

 the nerve fibres. 



All later inquirers (Kolliker, Boll, Heidenhain) have with 

 remarkable unanimity and with great precision described these 

 multipolar cells as indifferent structures forming a reticulum,

and properly to be regarded as belonging to the connective 

 tissue. According to Kolliker and Boll, these cells constitute 

 the membrana propria, which I have already described. 



The above-named inquirers silently assume that the opinion 

 I hold of the direct continuity of these multipolar cells with 

 the glandular epithelium by means of thick and anastomosing 

 fibres is erroneous. Boll was unable to discover these com- 

 munications, but refers to apparent connections, and is of 

 opinion that the multipolar cells, with their intercommunica-
