 plum diluted. Extracb of belladonna. New veffels from the 

 inflamed tunica adnata frequently fpread like a fly's wing upon 

 the tranfparent cornea, which is then called Pterigium. To 

 ftop the growth of this, the principal veflels ffoould be cut through 

 with a lancet. When the inflammation begins to decline, after 

 tiue evacuation any ftimulating material put into the eye increaf- 

 es ! i, which foon removes the new red veflels
