THE COKNEA 



After the. anterior portion has had every- 

 thing removed from it there will be left 

 nothing but the first coat or tunic of the eye 

 the anterior portion of the sclerotic and 

 the cornea, The way the cornea seems to fit 

 into the sclerotic is not quite as one is led to 

 believe when told that it fits into the sclerotic 

 much the same way in which a watch crystal 

 fits into a watch.* Holding this part of the 

 eye up to a strong light one will see that the 

 sclerotic seems to overlap the cornea in the 

 vertical axis. 



By using the tweezers the cornea may be split. 

 Nothing in the way of locating its layers can 

 be recognized, however, unless a section is 

 made for microscopic examination. The epi- 

 thelial may be scraped off when the cornea is 

 a trifle dry. This is the ocular epithelium re- 

 duced to a layer of flattened cells.
