It occupies all that cavity which is formed by thebones of the skull; and is surrounded by two membranes ; the firstor outermost of which is called the dura mater, wThich lines the insideof the skull, and prevents its eminences from giving injury to thedelicate structure of the brain. This membrane also serves anotheruseful purpose; it helps to prevent concussions of this organ; for,sending off large folds which enter between the divisions of thebrain, it separates the whole mass into portions, which by its parti-tions it supports and protects from pressure, in the different motionsand positions of the head.
