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 Conjunctimtis espe- 

 cially affects the lower lid, and particularly the cul- 

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

 semi-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. 

 Pterygium (a little wing, Gr.). — Quite a common 



affection, result of in- 

 flammation and from 

 constant exposure. 

 Consists of hypertro- 

 phy of conjunctiva, 

 and sub-conjunctival 

 tissue. In form it is 

 a triangular vascular 

 prominence, general- 

 ly at the nasal side of 

 the eye, with the base toward the inner canthus and its 

 rounded apex at the edge of the cornea, or encroaching 

 more or less viyon the cornea. We notice two forms>
