Having already in various ways put before you his skull, spout-hole, jaw, teeth, tail, forehead, fins, and divers other parts, I shall now simply point out what is most interesting in the general bulk of his unobstructed bones. But as the colossal skull embraces so very large a proportion of the entire extent of the skeleton; as it is by far the most complicated part; and as nothing is to be repeated concerning it in this chapter, you must not fail to carry it in your mind, or under your arm, as we proceed, otherwise you will not gain a complete notion of the general structure we are about to view.

In length, the Sperm Whale’s skeleton at Tranque measured seventy-two feet; so that when fully invested and extended in life, he must have been ninety feet long; for in the whale, the skeleton loses about one fifth in length compared with the living body. Of this seventy-two feet, his skull and jaw comprised some twenty feet, leaving some fifty feet of plain backbone. Attached to this backbone, for something less than a third of its length, was the mighty circular basket of ribs which once enclosed his vitals.
