The laminae of the feathers of birds are kept together by teeth that hook into one another, “as a latch enters into the catch, and fastens a door.” The eyes of the mole are protected by being very small, and buried deep in a cushion of skin, so that the apertures leading to them are like pin-holes in a piece of velvet, scarcely pervious to loose particles of earth.
