Those who now sail to India speak of the size of these animals and their mode of appearance, but as coming neither in bodies nor frequently, yet as repulsed by shouts and by the sound of trumpets. They affirm that they do not approach the land, but that the bones of those which die, bared of flesh, are readily thrown up by the waves, and supply the Ichthyophagi with the above-mentioned material for the construction of their cabins. According to Nearchus, the size of these animals is three and twenty orguiae in length.About 140 feet. Arrian says twenty-five orguiae, or about 150 feet.
