Now, this occasional inevitable sinking of the recently killed Sperm Whale is a very curious thing; nor has any fisherman yet adequately accounted for it.
Be it said, however, that the Sperm Whale is far less liable to this accident than any other species. Where one of that sort go down, twenty Right Whales do. This difference in the species is no doubt imputable in no small degree to the greater quantity of bone in the Right Whale; his Venetian blinds alone sometimes weighing more than a ton; from this incumbrance the Sperm Whale is wholly free. But there are instances where, after the lapse of many hours or several days, the sunken whale again rises, more buoyant than in life. But the reason of this is obvious.
