ing fibres between the two. The stroma of the conjunctiva 

 (kk, fig. 393) terminates as a thin wedge between the epithelium 

 and the tissue of the cornea. The latter (b V, fig. 393) is con- 

 tinuous with the sclerotic (b b"), the outer portions of the 

 sclera inclining more towards the central part of the thickness 

 of the cornea than the internal and middle, so that in a meri- 

 dianal section the part where the transparent cornea and the 

 opaque sclera meet is arcuate (fig. 393). It is very difficult to

 connective tissue of the sclerotic. 



In section and in specimens that have been teased out, the 

 two kinds of fibres appear to pass into one another without
