The only right that nature knows anything about is the right which she has conferred on every creature, to do whatever it is strong enough to do—and that is might. But when might is well guided, all is well.

And yet it has several smaller ones in its bill, besides. How is this done? For, to catch the big fish, it must have opened the beak a good deal. That one, however, is right at the base of the bill, as though it had been caught first. This, I think, supports my ideas as to the modus operandi. I do not see how so large a fish could be caught, without letting out any little ones that had gone before it. But if it were caught first, the beak, which can cut into the body, to the bird's convenience, need not be opened more widely, on the next occasion, than it would be if it held only a small fish. Did the big fish occupy any other position in the bill than that which it does, it would be against my theory; situated as it is, it is for it. Pray heaven, then, I don't see another puffin with a big fish!—for it may be held differently.

I have now seen, more in extenso, another young kittiwake killed by a herring-gull. Herring-gulls are
