(3) Then follows the ground substance, or sub- 

 stantia propria, of the cornea. This is composed of 



lamellae of bundles 

 of fibrous connective 

 tissue. Neighbouring 

 ! jj, lamellae are connected 

 with one another by 

 oblique bundles. 



The fibre bundles 

 within each lamella 

 run parallel to the sur- 

 face of the cornea, but 

 may cross one another 

 under various angles. 



In the anterior 

 layer of the ground 

 substance some of the 

 bundles pass through 

 several lamellae in an 

 oblique manner ; they 

 represent the fibrae 

 arcuatae. 



The fibrils within 

 the bundles, and the 

 bundles, and the la- 

 mellae of bundles are 

 held together by an 

 interstitial, albumin- 

 ous, semi-fluid, cement 

 substance, which, like 

 other similar intersti- 

 tial substances, be-
