in the cornea, and even here the parts were as transparent as other 

 portions of the eye. 



CATARACT— OPERATION. 



13. Six-year-old poodle affected with double cataract. Left in 

 hospital i6th April, i8g8. 



The first signs of disease in the eye had occurred two years before. 

 The lens of each eye gradually became opaque, though that of the 

 left eye was more rapidly affected than the right. 



State on Entry. — The lens of the left eye was completely opaque. 

 On the whitish ground formed by the lens a few striae, arranged in the 

 shape of a star, could be seen, and towards the centre several little 

 greyish spots. The right lens was opaque throughout, but the opacity 

 was a little less marked and more uniform than in the left lens. 



Vision was completely abolished. In unfamiliar spots the animal 

 continually ran against obstacles. 



Treatment. — We were asked to operate, and decided to deal first 

 with the left eye. For three days the eye was prepared by bathing 

 with warm solutions of 3 per cent, boric acid, and with i in 3000 

 sublimate. 



On the 19th the animal was anaesthetised with atropomorphine 

 and chloroform. The operation chosen was that in which the lens is 

 depressed, and was performed by the usual method. Trifling haemor- 

 rhage occurred under the conjunctiva at the point of puncture, and a 

 little blood also passed into the anterior chamber of the eye. During 

 the night the eye was several times fomented with wadding saturated 

 in warm boric solution. The animal's kennel was covered so as to 

 keep it in semi-darkness. The patient readily took milk and a little 

 meat. 



The same treatment was continued during the following days : 

 a little opacity appeared in the anterior chamber, but in a week it had 

 entirely disappeared, together with the effused blood and the ecchy- 

 mosis under the conjunctiva. Even at this stage there was marked 

 improvement. The dog saw sufficiently to choose its path and avoid 

 obstacles. It had no difficulty or hesitation in entering its kennel, 

 whilst previous to operation it always struck against the step in 

 front. 



Remark. — The observations of Berlin, Moller, Randolph, and 

 Contejean show that in the dog accommodation is soon restored. In 

 practice it is well to restrict operation to discission for soft cataracts, 

 and to depression for others. Without doubt these methods are very 

 inferior to extraction, but they have the double advantage of being 

 less dangerous and capable of performance by most practitioners. 



SYMBIOTIC ACARIASIS AND ECZEMA OF THE EAR. 



14. Six-year-old Havanese bitch, entered hospital 30th December, 

 1898. 



History. — During April, 1898, this bitch, which lived in its owner's 

 rooms, suddenly presented a concourse of symptoms apparently due to
