 epithelium of the fascia. Thus a serous sac or lymphatic space is formed 

 by the parietal layer of this sac, which lines the orbital cavity, in conjunc- 

 tion with the visceral layer which covers the posterior two-thirds of the 

 globe of the eye; this sac is the capsule of Tenon.

 surface of the palpebras or eyelids. The conjunctiva is a continuation of 

 the integument of the lid, modified so as to simulate a mucous membrane. 

 The portion associated with the eyelid is known as the palpebral con-
