In the pursuit of another inquiry, namely, the causation of fetal death, in which the examination of the medullae of the new-born was undertaken to determine the presence of hemorrhages,1 a certain set of minute histologic observations was selected, and this was adhered to for all the sections. These items were to include a scrutiny of the leptomeninges, the measured width of the vessel walls, the cellular and vascular content of the choroid plexus, the ependyma, the cranial nerve nuclei, the amount of neuroglia (by count in fields) in the substance of the medullae and the amount of myelin at this stage of development; this forms the subject matter of a communication to appear shortly.
This note is to record the discovery, made during the aforementioned histologic search, of a circular body in the fourth ventricle at the midolivary level, springing from the clothing cells of the ventricle. About
