    Post-mortem examination.—A large cyst, of the capacity of a bantam's egg, was met with, situated in the right portion of the pons Varolii (fag. 2). The parietes of this cyst, which consisted of attenuated nervous structure, Fig 2. This illustration exhibits a cyst in the substance of the right portion of the pons Varolii, which has been freely opened to show the interior. had given way at the thinnest part during the removal of the brain, owing to the firm adhesion which had formed between the cyst-wall and the dura-mater lining the base of the cranium ; and the interior of the cyst was seen to have been occupied by a quantity of light coloured and glairy albu- minous fluid, containing a number of white albuminous particles, being also lined by a thin film of albumino-fibrinous material. Its outer surface m one or two places had recent shreddy fibrinous material connected with it.* By means ot the cyst, the anterior part of the under surface of the right side of the cerebellum was mucli indented, the whole cerebellum having been, as it were, slightly twisted, and somewhat pushed over to the left side. The under surface of the middle cerebral lobe on the same side was also indented. More- over, the cyst, owing to its position, interfered with the fourth, fifth, and seventh pair of cranial nerves on the right side. Excepting thickening of the arach- noid membrane around the cyst, and distension of the lateral cerebral ventricles with clear fluid, the other parts of the brain were healthy. Remarks.—This cyst was no doubt the result of softening of some scrofulous deposit within the pons Varolii. Besides the symptoms clearly referrible to interference with the fourth, fifth, and seventh cranial nerves above mentioned, and which for my purpose require in this place no comment or further enumeration, this case shows * This preparation is now In the St. George's Hospital Pathological Museum, as Prepa- ration Mo. 11a, Sub-series iv., Series xx.
