If you flatter yourself that you are all over comfortable, and have been so a long time, then you cannot be said to be comfortable any more.

But if, like Queequeg and me in the bed, the tip of your nose or the crown of your head be slightly chilled, why then, indeed, in the general consciousness you feel most delightfully and unmistakably warm.

For this reason a sleeping apartment should never be furnished with a fire, which is one of the luxurious discomforts of the rich.

For the height of this sort of deliciousness is to have nothing but the blanket between you and your snugness and the cold of the outer air.

Then there you lie like the one warm spark in the heart of an arctic crystal.
