the bottom, the bird could no doubt pinch up the skin so as to get a secure hold of it. The various little tactile movements of the mandibles upon the fish by which the latter would be first grasped between, and then passed carefully down them, to lie against the one last caught, can be pretty well imagined, and they could be very effectively aided by the rubbing or pressing of it, on either side, against the sand, rocks, stones, etc., of the bottom. It must be remembered, too, that the mandibles open like a scissors, so as to be wider apart at the tips than at the base, which would diminish the difficulty; and moreover, each fish is so deeply indented by the sharp, cutting blades—which, however, do not seem to pierce the skin—that, although alive—reflecting possibly on the beauty of maternal affection—they would be likely to "cleave to their mould" like putty, for a little while after the pressure were relaxed.

I think that the broad, blade-like bill of the puffin has to do with this power that the bird possesses of holding many fish at a time, and that the razorbill whose beak is of the same type, and who bites the fish across in just the same way, is in the habit of doing so also. Be this as it may, the guillemot, whose bill is quite differently shaped, holds the fish, as a rule, in a different manner, longitudinally namely, with the head towards the throat, and the tail drooping over to one side. This is not invariable; but I have never myself seen a bird bring in more than one fish at a time. It is the same, I think, with the black
