ACCESSORY ORGANS OF THE EYE: 
With a morstened sponge clean the exposed portion of 
the eyeball and the eyelids from dirt. 
I. The Eyelids. The upper and lower eyelids di- 
verge from each other, leaving an oval space through 
which the front of the eyeball is seen. The points at 
which the two lids meet are known as the inner and 
outer angles or canthi of the eye. 
2. The Meibomian Glands. On the inner margin 
of the edge of each lid will be seen a number of short 
yellowish lines passing inward for a short distance, 
arranged at right angles to the free edge: these are 
the Meibomian glands. 
3. The Conjunctiva. The under or inner surface of 
each lid is covered by a loose mucous membrane, the 
conjunctiva. Follow this backward into the orbit ; it 
is soon reflected upon the surface of the eyeball, 
covering over the whole of the exposed portion. The 
conjunctival mucous membrane consists then of two 
parts, one covering the inner surface of the eyelids 
and one the external surface of the eyeball. The line 
along which the mucous membrane is reflected from
