 sus. Where it passes from 

 the lids to the globe it is 

 thin and very loose and 

 forms thefornix conjunctivce. 

 Now, as its name indicates, 

 it joins the bulbus and pal- 

 pebrse together. It envelops, in addition to the above, 

 the anterior portion of the haw {membrana nictatans) 

 in a particular fold, and covers the caruncula lachry- 

 malis and enters the puncta. At the margin of the 

 cornea one may not trace it, although it is represented 

 by a layer of pavement epithelium. At the surface of 

 the caruncle it shows some very fine hair bulbs. (See 

 conjunctiva.) 



Eyelashes (cilia.) — Two rows, at free borders of the 

 lids. Act as a shield against foreign particles, dust, 

 etc. Their follicles are surrounded by sebaceous glands 

 and the glands of Moll (which are small tubular glands 

 resembling ceruminous glands.) 



These various glands serve to lubricate the eye by
