every second or third day, not oftener, or the animal will 
suffer; together with applications twice' a day of the mer¬ 
curial col. until the opacity is removed. The salt and water 
solution is to be used daily to remove discharge, and also 
allowed to run into the conjunctival sac. In operating, care 
must be used in making the puncture, as a large opening may 
result in a disastrous fistula; also in the directing of the knife 
in puncturing, use care so as not to wound the iris. This can 
easily be avoided by not entering the anterior chamber 
too deeply, and by directing the knife in the direction of the 
centre of the cornea. Complications may ensue of hernia of 
the iris, ulcer of the cornea, or anterior synechia, together 
with fistula, and escape of the lens and vitreous already men- 
tioned ; 
these, 
however, can be avoided bv 
7 m/ 
care and clean- 
liness, and judgment 
in operating.
