Bees’ Multiple Eyes.

Every bee has two kinds of eye*— two large, compound ones looking like hemispheres on either side and three simple or single eyes, which crown the head. Each compound eye is really an immense aggregation of eyes, composed at 3,500 facets, which means that every object seen has its image reflected 3,500 times In the bee’s tiny brain. Every one of these facets Is the base of an in'verted hexagonal pyramid, the apex of which is fitted snugly to the head. Each ■ of these pyramid facets may be termed a perfect eye. for it has its own iris and optic nerve.
