A word or two more concerning this matter of the skin or blubber of the whale. It has already been said, that it is stript from him in long pieces, called blanket-pieces. Like most sea-terms, this one is very happy and significant. For the whale is indeed wrapt up in his blubber as in a real blanket or counterpane; or, still better, an Indian poncho slipt over his head, and skirting his extremity. It is by reason of this cosy blanketing of his body, that the whale is enabled to keep himself comfortable in all weathers, in all seas, times, and tides. What would become of a Greenland whale, say, in those shuddering, icy seas of the North, if unsupplied with his cosy surtout?
True, other fish are found exceedingly brisk in those Hyperborean waters; but these, be it observed, are your cold-blooded, lungless fish, whose very bellies are refrigerators; creatures, that warm themselves under the lee of an iceberg, as a traveller in winter would bask before an inn fire; whereas, like man, the whale has lungs and warm blood. Freeze his blood, and he dies. How wonderful is it then—except after explanation—that this great monster, to whom corporeal warmth is as indispensable as it is to man; how wonderful that he should be found at home, immersed to his lips for life in those Arctic waters! where, when seamen fall overboard, they are sometimes found, months afterwards, perpendicularly frozen into the hearts of fields of ice, as a fly is found glued in amber. But more surprising is it to know, as has been proved by experiment, that the blood of a Polar whale is warmer than that of a Borneo negro in summer.
