The skeleton is formed of heavy bones containing marrow. The skull (tig. 667) is a spacious capsule, the bony pieces of which art- only exceptionally (Ornithorhynchus) fused in early life, but as a rule they remain for the most part separated by suture throughout life. There are, however, many cases in which in the adult animals the sutures have partly or wholly vanished (Ape, Weasel). The great extension of the cranial capsule is due not only to the large size of the roof of the skull, but also to the fact that the lateral bones.
