1, epithelium ; 2, anterior homogeneous lamina ; 3, snbstantia propria eornese ; 4, posterior 

 homogeneous (elastic) lamina ; 5, epithelium of the anterior chamber ; a, oblique fibres 

 in the anterior layer of the substantia propria ; 6, lamellae, the fibres of which are cut 

 across, producing a dotted appearance ; c, corneal corpuscles appearing fusiform in section ; 

 d, bundles of fibres cut longitudinally ; e, transition to the sclerotic, with more distinct 

 fibrillation, and surmounted by a thicker epithelium ; /, small blood-vessels cut across 

 near the margin of the cornea. 



The sclerotic coat is composed of dense fibrous tissue, the bundles 

 of which are intimately interlaced. It is thickest at the back of the
