The cornea may be considered as the shield that protects the eye, yet in consequence of its transparency, it is also operative in the production of vision. 4:th. Iris. — This is the movable curtain of the eye, adapts the eye to vision, possesses the property of contraction and ex- pansion ; in its centre is a perforation commonly known as the pupil. The dimension of the pupil depends entirely on its conti-action and dilatation ; in a very dark barn (provided the eye be in a healthy condition), ...the pupil will be very much di- lated ; in a barn well lighted the pupil will be quite small. The iris is a fibro-muscular membrane, abundantly supplied with blood-vessels and nerves, and coated with a, substance known as uvea which is derived from the pigment. The arte- ries of the iris come from the ciliary, its nerves are derived from the ciliary. 5th. Choroid Coat. — This coat or membrane lies beneath the sclerotica ; it extends from the optic foramen to the ciliaiy edge of the cornea ; both of its surfaces are coated with pig- mentj which absorb the rays of light ; the outer coating is en- tirely black ; the inner one is a mixture of black and green, which lines the posterior half of the dark chamber.
