    half to one inch posterior to the coronal suture, and the upper two inches. The m )tor centres are found in the convolutions on each side of the fissure. CONTUSION OF THE SKULL. This form of injury can only take place in those parts of the skull where the diploe is present. They are not such serious in- juries as Pott and others believed, except where there is an external wound. Suppuration and osteomyelitis have, however, been occasionally observed. Contusions are frequently produced by gun-shot. Necrosis of the part struck; suppuration in the bone, or between it and the dura-mater, followed by pyaemia, may take place. Contusion or laceration of the brain substance, either at the place struck, or the opposite side of the brain, may also occur. Con- tusions in the temporal and frontal regions are most liable to the dangerous consequences which occasionally follow this form of injury. FRACTURES OF THE SKULL. These injuries form 278 per cent, of all fractures. They do not present the ordinary symptoms of fracture elsewhere. Mobility, crepitus, deformity, or even much displacement are usually absent. Their serious nature chiefly depends upon the associated injury of the brain. Fracture of the skull may be simple or compound, may be associated with more or less extensive injury to the brain, and laceration of the dura-mater, or this membrane may be intact. Fractures are the result of external violence. They are divided into those of the base and those of the vertex. Each variety may present peculiar symptoms. The nature and causes of the injury and its effects differ in individual cases, as also do the diagnosis, prognosis, and treatment. FRACTURE OF THE BASE. These fractures, as a rule, assume the form of fissures, are usually compound, and very often fatal in their consequences.
