A circnniscribed swelling connected with the bone Nodes, and periosteum, attended by considerable pain, worse at night, appearing on the cranium shortly after the receipt of an injury, is a traumatic node, the result of a localised inflammation of the periosteum. 24. A f ungating mass, of ten pulsating synchronously Hernia Cerebri, with the brain, consisting of cerebral substance, more or less mingled with inflammatory products, following laceration or sloughing of the dura mater, the result of a com]30und fracture of the skull, or the removal of a portion of the skull-cap with a trephine for injury or disease, is a hernia cerebri or protrusion of the brain. It is termed a false hernia cerebri when the protruded mass consists mainly of inflammatory exudation and granulation tissue, and true hernia cerebri when it is composed chiefly of real cerebral substance. 25. A small fluctuating swelling, situated upon some Collections of . . . cerebro-spinal part of the vault of the cranium, m some cases exhibit- fluid, ing slight pulsation, more or less completely reducible, varying in size from time to time, but generally be- coming larger and more tense during violent expiratory efforts or on lowering the head, usuaLy occurring in children, and following an injury to the head, generally unaccompanied by any external wound, is a collection of cerebrospinal fluid beneath the tissues of the scalp.* This condition is generally the result of a simple fracture of the vault of the skull, whereby the subarach- noid space, or possibly one of the ventricular cavities cf the brain having been laid open, the cerebro-spinal fluid escapes through the crack or fissure in the bone, and gives rise to the localised swelling beneath the tissues * Clement Lucas, ' Guy's Hospital Reports,' 1876, 1881.
