The large anterior lobe appears to be made up of two distinct portions (histologically 
distinct), viz. a front part composed of syncytial strands of cells, with well-defined nuclei 
and a few intervening sinusoids, or rather capillaries, since the endothelial walls are

large clumps of cells, the cell-outlines being quite distinct and the majority of them 
having deeply stained cytoplasm of a somewhat granular character; the nuclei are

large and distinct.* In this part many large sinusoids occur, filled with erythrocytes ; 
a few of the above-mentioned deeply-staining cells occur in the front part of the anterior 
lobe, but the majority in the front part are syncytial and the cytoplasm but lightly 
* In these clumps, some of the cells possess much clearer cytoplasm, which is not deeply stained with eosin ; 
in this respect the anterior lobe resembles that of the human pituitary gland.
