Treatment. — Tapping through the sclerotica, followed 

 by continuous pressure, secondary infiltration may occur, 

 and tapping may be again resorted to. This treatment has 

 been successfully adopted by the author on two occasions, 

 the eye being punctured immediately behind the outer 

 margin of the cornea. In one operation a drachm of clear 

 watery fluid was removed ; in the other, half-an-ounce of 

 a deep amber-coloured fluid, approaching red. After each 

 evacuation the eye assumed its natural size and position ; 

 a cold wet sponge was placed over it, and maintained in 

 situ by a head cap. The sponge was re-applied daily for a 

 week ; and then one drop of a weak solution of iodine was 

 each morning placed on the eye-ball for the removal of 

 the opacity, and the result proved satisfactory. In persistent 

 cases the iapplication of iodine round the eye, and atropine 

 injections, are sometimes beneficial. 



Congenital dropsy of the aqueous chambers is not un- 

 frequently present in in-bred dogs, especially toys.
