Magnified 300 am indebted to Mr Edgar Beard for the specimen from which this microphotograph wastaken. The cell protoplasm and the reticular tissue between the cells are well shown. Sections of human pineal show it to be composed of epithelium-like cellsarranged in loosely disposed trabeculse with large sinus-like blood-vesselsbetween the trabeculae (fig. 83). In some animals plain muscular tissue,and even striped muscle, has been described in the intertrabecular tissue. 120 The Endocrine Organs The blood-vessels are very numerous. There are no true nervous elements,with the exception of a few fibres perhaps destined for the blood-vessels,but neuroglia cells and fibres are present in abundance. Embedded bothin the interstitial tissue and in the covering of the pia mater are smallround globules of calcareous matter—corpora amylacea, brain sand—which are much more common in man than in other animals, an
