freezing Arctic cold, while the uselessness of legs has been avoided 

 by changing the fore limbs into paddles and enclosing the hind ones 

 in the body, where a rudimentary form of them still exists. Only 

 one condition of life escapes her skill; the whale can breathe noth- 

 ing but air and must rise to the surface to get it. Even here she 

 has modified the matter by making it possible for one long breath of 

 one to two minutes to last him during a ten to twenty minutes' stay 

 under water, nor did she forget to adapt his tail peculiarly to this 

 difficulty by a horizontal shape, differing from that of his fish neigh- 

 bors, but just what he needs for the quick upward stroke when he 

 must go to "blow." In this connection it should be said that the 

 "spouting" at these times is due to the rapid condensation of the 

 warm vapor of the breath when it strikes the chill atmosphere, ex- 

 actly as moisture collects on a window pane against which we 

 breathe, and had nothing to do with any water taken in by the whale 

 with his food.
