highly refractive. Then the (5) endothelial layer, com- 

 posed of a single layer of cells. This layer is reflected, 

 on the anterior surface of the Iris. In or on the cornea 

 <tre no blood vessels. The anterior ciliary arteiies 

 furnish branches, which approach the limbus, forming 

 loops. Blood vessels on the cornea are indicative of 

 either a pathological condition or an attempt of 

 nature to repair. The nerves come from the ciliarj'-, 

 which pass the ciliary body and form a plexus around 

 the border of the cornea. Their terminal fibrillse are 

 most abundant in the epithelium and anterior layers 

 of the cornea. Some few twigs come from the con- 

 junctival nerves. 



Injuries and Wounds.— Many varieties — clean cut, 

 -contused, scraped, etc. Clean cut, if not too large, 

 usually heal and leave no trace. Contused wounds 

 are apt to cause suppuration. 



The great danger is of injury to the lens, which 

 would be apt to result in cataract, or to the iris, which 

 may prolapse, or, becoming adhered to the corneal 

 puncture, cause staphyloma. 



Treatment — The primary treatment is to place the 

 eye in a state of rest and allay irritation by soothing 

 applications. Atropine and cocaine should be applied 

 several times daily ; atropine 1 to 120, or stronger if 

 need be ; cocaine 4%. Cold compresses if seen early 

 enough. If the epithelium is abraded a few drops of 

 olive oil allays irritation. The compress bandage re-
