The sutures are visible also inside the skull

It should not be thought because of the false doctrines of certain people 72 that these agglutinations are less visible in the hollow of the skull where the brain lies than the three sutures previously described, and for this reason are never called sutures.

Their outline (L L in figure 6) [sutura parietomastoidea et squamosa] can be seen inside the skull exactly as that of the sutures, which do not look as much like sutures inside the skull; but because they are less convoluted, especially the coronal suture, they look more like a line [sutura plana] or a harmonia. These squamous agglutinations are not joined along their entire course like scales resting on top of each other. For at the point where they first leave the lambdoid suture, they take on the look of a suture outside and inside the skull for some distance (C to G in figs. 3, 4). Moreover, the portion of these agglutinations that is closest to the coronal suture (H to A in figures 3 and 4) must also be considered common to the vertex [os parietale] and the cuneiform bone (O in figs. 3, 4) [os sphenoidale].
