THE LACHRYMAL GLAND 203 



Light cells: The light cells correspond to the large bulging 

 cells (type 1) heretofore described. The secretory granules are 

 not preserved in this solution but an intergranular cytoplasmic 

 network remains. The meshes, which originally possessed 

 granules, now appear empty. This condition is seen also in 

 tissues fixed in Zenker's solution. Irregularly distributed 

 throughout this dark stained cytoplasmic network are seen these 

 minute fuchsinophil granules or mitochondria. The majority 

 are slightl}' elongated simulating somewhat bacilh. Others 

 again are round, cocci like. They are seen in every portion of 

 the cell from the base to the summit, (fig. 14). In no instance

have I seen in these large bulging cells mitochondria arranged 

 in the form of filaments at the base of the cell. Nor is this to 

 be anticipated, for these cells in other fixations (formalin Zenker 

 and alcohol bichromate sublimate solution) are filled with gran- 

 ules from the base to the summit. Occasionally larger fuchsino- 

 phil granules are seen which resemble the secretion granules in 

 size and shape, and are seen surrounded by the darker cyto- 

 plasmic network. These secretion granules when present show 

 as much affinity for fuchsin as do the mitochondria. I have
