the new growth. There is also general lymphoid infil- 

 tration of the conjunctiva and of the deeper tissues of 

 the lid, including the tarsus, also great proliferation 

 of epithelia and formation of new vessels. In papil- 

 lary trachoma, the location is predominately over the 

 surface of the tarsus, instead of its borders. The 

 enlarged papillae are bright-red, or sometimes red 

 with a bluish cast. Follicular Conjuncpivitis espe- 

 cially affects tlie lower lid, and particularly the cul- 

 de-sac. The follicle is round, or elongated, pale and 

 serai-transparent. Is more prominent and sharply 

 raised above the surface of the conjunctiva, and can 

 be removed or separated from it. Its general arrange- 

 ment is in rows parallel to the free margin of the lids.
