Puzzling

A curious and most puzzling question might be started concerning this visual matter as touching the Leviathan. But I must be content with a hint. So long as a man’s eyes are open in the light, the act of seeing is involuntary; that is, he cannot then help mechanically seeing whatever objects are before him.

But, peradventure, it may be sagaciously urged, how is this? We thought the tissued, infiltrated head of the Sperm Whale, was the lightest and most corky part about him; and yet thou makest it sink in an element of a far greater specific gravity than itself.
