cells stain red in mucicannin and all the gi'anules in other cells 

 stain black in iron haematoxylin while in still others both red 

 and black granules are seen in the same cell (fig. 13.) 



Copper chroine haematoxylin. Sections stained in copper 

 chrome haematoxylin show the granules to be deeply stained. 

 The cells are readily classified into the three types already 

 described. The large bulging cells are filled with black stained 

 granules of various sizes. The granules in the type 2 cells are 

 very lightly stained — in many they are so faintly stained that

it is difficult to make out any granules whatsoever. The type 3 

 cells are filled with black granules. 



Sections fixed in the sublimate alcohol bichromate solution 

 and stained in copper chrome haematoxylin show, in the larger 

 ducts, mitochondria either as irregularly distributed granules 

 or as filaments (see Mitochondria.) 



Neutral gentian and safranin-acid violet. These proved to be 

 excellent stains for granules in the lachrymal gland. Tissues 

 fixed in either the sublimate alcohol bichromate or the formalin 

 bichromate sublimate solution show the characteristics alreadv
