<on that fide, where the pain was. 
I prefume it will not be difficult to conceive, how 
it fhould happen, that thefe inflammations fhould ex- 
cite fuch different fymptoms, when we reflect, that, 
in the incifion of the cornea, the cornea only fuffers ; 
and in couching, the CQftjttnftiva, the Jclerotica , the 
choroides , and the tunica retina , are puncftured ; 
moft of which organs are either tendinous or nerv-

examination. However, this is not to be underftood 
as a conftant fact ; fome patients diftinguiftfing ob- 
jects immediately from the time of the operation.
