The edges of these bones are fringed with hairy fibres, through which the Right Whale strains the water, and in whose intricacies he retains the small fish, when openmouthed he goes through the seas of brit in feeding time. In the central blinds of bone, as they stand in their natural order, there are certain curious marks, curves, hollows, and ridges, whereby some whalemen calculate the creature’s age, as the age of an oak by its circular rings. Though the certainty of this criterion is far from demonstrable, yet it has the savor of analogical probability. At any rate, if we yield to it, we must grant a far greater age to the Right Whale than at first glance will seem reasonable.
