The morphology and evolutional significance of the pineal body : being part I of a contribution to the study of the epiphysis cerebri with an interpretation of the morphological, physiological and clinical evidence . -. THE PINEAL BODY 183 4. Zaiophus californianus. In the sea-lion, although it isdifficult to discern the four types of cells already described withclearness, as in the forms already noted, nevertheless, in certainareas there appear many large cells with extensive nuclei whichstain deeply. Here and there scattered throughout the bodyappear large cells of relatively the same size as those just men-tioned, the nuclei of which, however, stain but faintly. Smallcells with deeply staining pycnotic nuclei are present in numbersabout equal to that of the first type while a small variety ofcell whose nucleus stains feebly is the least common varietyobserved. The cells arrange themselves in cords or columnswhich, upon transverse section, seem to be circular. Thesecords apparently are much convoluted and not infrequently asection of what appears to be the same cords is seen in transverseas well as longitudinal outline. There is a rich connective tissuenetwork which appears to surround the cell cor
