* The essential parts of the eye are inclosed in a tough outer coat, the sclerotic, to which the muscles moving it are attached, and which in front changes into the transparent cornea. A little way back of cornea, the crystalline lens is suspended, dividing the eye into two unequal cavities, a smaller one in front filled with a watery fluid, the aqueous humor, and larger one behind filled with a clear jelly, the vitreous humor. The sclerotic is lined with a highly pigmented membrane, the choroid, and this is turn is lined in the back half of the eyeball with the nearly transparent retina, in which the fibers of the optic nerve ramify. The choroid in front is continuous with the iris, which has a contractile opening in the center, the pupil, admitting light to the lens which brings the rays to a focus and forms an image upon the retina, where the light, falling upon delicate structures called rods and cones, causes them to stimulate the fibres of the optic nerve to transmit visual impressions to the brain.
