Abstract
IN an investigation of the histology of the pituitary of the perch (Perca fluviatilis) a process of some general interest has come to light. Cells having the appearance of eosinophile leucocytes are present in the middle glandular or transitional lobe, and from them can be traced a succession of cells with fewer and larger inclusions to precise and brightly staining eosinophilic spheres which come ultimately to lie free among the cells of the lobe. In some series these spheres can be seen in all locations from the transitional to the nervous lobe, where they represent the larger elements of the Herring material in this form. Here in turn they appear to break down and form a characteristic granulation.
