Anatomy

Now comes the Baling of the Case. But to comprehend it aright, you must know something of the curious internal structure of the thing operated upon.

Regarding the Sperm Whale’s head as a solid oblong, you may, on an inclined plane, sideways divide it into two quoins,* whereof the lower is the bony structure, forming the cranium and jaws, and the upper an unctuous mass wholly free from bones; its broad forward end forming the expanded vertical apparent forehead of the whale.

And what is still more, for many feet after emerging from the brain’s cavity, the spinal cord remains of an undecreasing girth, almost equal to that of the brain. Under all these circumstances, would it be unreasonable to survey and map out the whale’s spine phrenologically? For, viewed in this light, the wonderful comparative smallness of his brain proper is more than compensated by the wonderful comparative magnitude of his spinal cord.
