Rh from the cerebellum through, the spinal canal. For I believe that much of a man's character will be found betokened in his backbone. I would rather feel your spine than your skull, whoever you are. A thin joist of a spine never yet upheld a full and noble soul. I rejoice in my spine, as in the firm audacious staff of that flag which I fling half out to the world.

Apply this spinal branch of phrenology to the Sperm Whale. His cranial cavity is continuous with the first neck-vertebra; and in that vertebra the bottom of the spinal canal will measure ten inches across, being eight in height, and of a triangular figure with the base downwards. As it passes through the remaining vertebræ the canal tapers in size, but for a considerable distance remains of large capacity. Now, of course, this canal is filled with much the same strangely fibrous substance—the spinal cord—as the brain; and directly communicates with the brain. 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.

But leaving this hint to operate as it may with the phrenologists, I would merely assume the spinal theory for a moment, in reference to the Sperm Whale's hump. This august hump, if I mistake not, rises over one of the larger vertebræ, and is, therefore, in some sort, the outer convex mould of it. From its relative situation then, I should call this high hump the organ of firmness or indomitableness in the Sperm Whale. And that the great monster is indomitable, you will yet have reason to know.
