A. a shortsighted eye; B. an arrow which it attempts to perceive, but is prevented by the convergence of the passage of the visual rays to foci, at C., before they reach the retina at D. E. the same eye similarly situated, showing how by the interventions of a concave lens, G., the rays are diverged, and the image of the arrow, F., accurately converged to the retina at A.

The tear gland of the eye. The tears are carried from this factory b little ducts (b) and are poured over the surface of the eye. They serve to keep the eye moist, so that it can be moved about in its socket easily by the muscles. They also serve to wash out substances that get into the eye. The tears go into openings (c c) and pass through two ducts which unite in one (d e) which ends in the nose.

"Diagrams illustrating two stages in the development of the vertebrate eye. A, showing the relation of the ectoderm, the brain vesicle, and the optic vesicle. The right side of the figure shows a later stage than the left. B, later stage, showing the lens, eye-ball and retina in position. b.v., brain vesicle formed by the invagination oof the ectoderm (ect.); l, lens; mes., mesodermal tissue; o.n., optic nerve; o.s., optic stalk; o.v., optic vesicle, a portion of the brain vesicle; r, retinal layer; v.h., interior of eye-ball which comes to contain the vitreous humor." — Galloway
