The head is generally divided into the Cranium, or that part which contains the brain, and the Face.

Plate XXIV.
The head is generally divided into the Cranium, or that part which contains the brain, and the Face.
The bones of the cranium are not closed together, as they are in the adult, but are separated to a considerable distance, in certain parts, and connected by a strong membrane. These membranous spaces are called Sutures and Fontanelles, and a knowledge of them is absolutely necessary, as a means of ascertaining the position of the head.
