At this point theforce recedes or diminishes, permitting the outer table toresume, through its elasticity, its normal contour. Depressed fractures are never seen at the base, butusually a fissure runs from the anterior or posterior con- 86 RAILWAY SURGERY. dyloid fossa, irregularly up on the sides of the base of theskull (see Fig. 38). All fractures of the vertex are associated with a lesionof the soft parts, and are frequently in a state of comminu-
