But look at the penguins of the Southern Ocean; have not these birds their front limbs in this precise intermediate state of "neither
true arms nor true wings"?
Yet these birds hold their place victoriously in the battle for life; for they exist in infinite numbers and of many kinds.
I do not sup- pose
that we here see the real transitional grade
through which the wings of birds have passed; but what special difficulty is there in believing that it might profit the modified descendants of the penguin, first to become enabled to flap along the surface of the sea like the logger-headed duck, and ultimately to rise from its surface and glide through the air?
