The diploe is the most porous, the softest, and most cavernous part.
-
The bone at the middle of the head is double, the hardest and most compact part being the upper portion, where it is connected with the skin, and the lowest, where it is connected with the meninx (dura mater); and from the uppermost and lowermost parts the bone gradually becomes softer and less compact, till you come to the diploe.
-
The tough outer table is more difficult to cut than the softer and more vascular diploe, and the inner table is denser than either, but more brittle.
A Manual of the Operations of Surgery For the Use of Senior Students, House Surgeons, and Junior Practitioners Joseph Bell 1874
-
In many old skulls, however, the diploe is wanting altogether, and the two tables are amalgamated, and often very thin.

It consisted of its two well-marked tables of solid bone, corresponding in their dermal character, the outer to the cuticle, the inner to the true skin, and the intermediate cellular layer to the _rete mucosum_; but bearing an unmistakable analogy also, as a mechanical contrivance, to the two plates and the _diploe_ of the human skull.
-
The spongy middle plate must, like the diploe of the skull, have served to deaden the vibrations of a blow dealt from the outside.
