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



tions, in some instances closely resemble salivary cells, so that 

 the possibility of a false impression is conceivable. 



But as I am satisfied that I have seen the connection of the 

 multipolar cells with salivary cells, I hold it to be my duty, 

 especially on account of the importance of all that depends upon 

 it, to prove this point with the most rigorous scientific accu- 

 racy. As I have more recently on many occasions observed such 

 connection, I may remark that we are here engaged with the 

 examination of completely isolatable cells, which communicate 

 with one another by means of a thick anastomosis, and the two 

 points of attachment of which may be seen in perfect profile 

 (fig. 90, ABC). One of these cells is pale, striated, with many 

 radiating processes, and with the body almost entirely filled 

 with the. nucleus (fig. 90, B). The other is round or slightly poly- 

 gonal, with abundant granular protoplasm and a relatively 

 small nucleus.

As the observations were made upon rabbits, the fully deve- 

 loped salivary cells of which have so stereotyped an appear- 

 ance, I regard it as absolutely impossible that I should have 

 mistaken any other cell for a salivary cell. Moreover, I have 

 actually seen the connection whilst the salivary cells in 

 question were still adherent to others, and forming part of the 

 characteristic mosaic (fig. 90, A and c). 



It follows therefore that the multipolar cells cannot be con- 

 nective tissue cells, as maintained by Kolliker, Heidenhain, and 

 Boll ; for the true salivary cell is an enlargement of a medul-
