stains, referred to later, were employed for the differentiation of the 
cellular elements in the gland. 
THE STRUCTURE OF THE NoRMAL Restinc GLAND. 
If a thin, fresh section of the normal resting gland be examined in 
aqueous humor, with low magnification, the two cell groups described 
by Miiller can readily be discerned. Many cells, occurring always in groups

are found to contain highly refractive granules, while other less con- 
spicuous groups of cells are filled with granules of a low refractive index. 
Light and dark areas in the gland are thus mapped out with sharp 
distinctness, even with slight magnification. An examination under high 
magnification reveals the fact that all of the cells of both groups are 
loaded with granules. From this it can be at once inferred that the 
granules found in sections of the fixed gland are not artefacts produced 
by the precipitating action of the hardening fluid, but are in reality 
pre-existent in the cells. In the fresh preparation, a careful ‘examination
