Fig. 30 Sagittal section of the glandular cords of the superior lobe of an 
adult. X 400. 
The nuclei of the columns are spherical in shape, crowded close 
together in the center, and contain a light chromatin network 
and a nucleolus. Between these columns are numerous sinusoids. 
Along the periphery of the columns is a thick layer of granular 
cytoplasm, the granules being small and closely crowded (fig. 30). 
The cytoplasm frequently takes a distinctly acid stain. In 
some eosin-methylene blue preparations the cytoplasm of the 
superior lobe along the periphery of the columns is stained blue. 
With iron hematoxylin this same zone sometimes retains the 
hematoxylin longer than does the chromatin. The granules 
of this part often stain an intense blue with Mallory’s phos- 
photungstic acid stain. On either side of a granular area which 
stains very deeply there may be a clear area where the secretion 
possibly may be forming or has just been given up. I cannot, 
therefore, agree with Tilney (711) who finds only eosinophilic 
cells in the superior lobe and basophilic:in the anterior lobe. 
Besides, as has been noted, in many cases the cells of the anterior 
lobe take eosin quite as readily. Stendell (’13) thought that the 
division of chromophobie and chromophilic portions as described 
by Sterzi and others might not be true in all cases. In the adult 
Acanthias, it seems to me this distinction cannot be sharply 
drawn, at least not with all stains. The cytoplasm of the supe-
