 the eyeball and the eyelids from dirt. 



1. 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 eve. 



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

 and one the external surface of the eyeball. The line 

 along which the mucous membrane is reflected from
