    In a paper on the Cocainised Eye, before the Ophthalmo- logical Society on January 8th, 1885, I mentioned the use of the combination of cocaine and atropine in producing a very large dilatation of the pupil, and showed how this could be utilised in cases of iritis. Since then I have been trying how best to use such a combination, but the ex- pense of the drug till lately has restricted me in the number of my cases. I first tried using cocaine at the hospital after the patient had been using atropine in the intervals of his visits, and hoping, perhaps, that the increased mydriasis produced might be kept up by the atropine used at home. A solution of atropine and cocaine was next tried when the patient could afford to pay for it, but finding how badly such a solution keeps, even with care, I gave it up for some discs which Messrs. Savory and Moore made for me. Those discs contain -^^^ grain of cocaine hydrochlorate and ■jiiVo grain of atropine in each, and have answered all my requirements, being easy of application, constant in action, and very reliable. The following case in a healthy eye shows how quickly this combination produces an ad niaxt- miim dilatation of the pupil. E. G , aged six, pupils 5 mm., equal, act well to light and accommodation; 2.24 p.m., disc of cocaine and atropine in left eye; 2,29p.m., no effect on pupil, slight
