mucous membrane extends in the shape of minute 

 papillae. In the conjunctiva palpebrse the epithelium 

 is thin, but stratified pavement epithelium; there are 

 no papillae, but the sub-epithelial mucosa that is, the 

 layer situated between the epithelium of the surface 

 and the tarsal-plate contains a dense network of 

 capillary blood-vessels. 



402. Passing from the eyelids on to the eyeball, 

 we have the continuation of the conjunctiva palpebrse 

 i.e., the fornix conjunctive and, further, the con- 

 junctiva fixed to the sclerotic, and terminating at the 

 margin of the cornea the conjunctiva bulbi. The 

 epithelium covering the conjunctiva fornicis and con- 

 junctiva bulbi is stratified epithelium, the superficial 

 cells being short columnar; next to the fornix the 

 superficial cells are beautiful columnar, and the 

 mucosa underneath the epithelium is placed in regular 

 folds (Stieda, Waldeyer). Towards the cornea the 

 epithelium of the conjunctiva assumes the character 

 of stratified pavement epithelium, and minute papillae 

 extend into it from the mucosa, 



403. The mucous membrane is fibrous tissue, 

 containing the networks of capillary blood-vessels. 



Into the fornix lead minute mucous glands, em- 

 bedded in the conjunctiva fornicis ; they are the glands 

 of Krause. Similar glands exist in the distal portion 

 of the tarsal-plate. 



404. The blood-vessels of the conjunctiva ter- 

 minate as the capillary network of the superficial 

 layer of the mucosa, and as capillary networks for the 

 Meibomian glands, Krause's gland, &c. Around the 

 corneal margin the conjunctival vessels are particu- 

 larly dense, and loops of capillaries extend from it 

 into the very margin of the cornea. 



405. The lymphatics form a superficial and 

 deep network. Both are connected by short branches. 

 The deep vessels are possessed of valves. The super-
