    purchased, but it is better for the surgeon to prepare this for himself. Sponges maybe needed in plastic operations or in enucleations. They should be properly prepared. Generally the area of opera- tion may be kept dear by gently touching it with cotton soaked in a bichloride solution, or with gauze which lias been sterilized by heat. Anaesthesia.—The indications for general anaesthesia in oph- thalmic surgery are limited. In children or in very nervous adults, and for enucleations, blepharoplastic operations, advance- ments of the muscles, and in some cases of glaucoma, general anaesthesia is necessary. The surgeon must decide between ether and chloroform. As the former is certainly safer than chloro- form, or the mixture of chloroform, ether and alcohol, its use is to be preferred. Cocaine may be employed in two or four per cent, solution, and should be freshly prepared, two per cent, of boric acid being added to the mixture. In lid operations it may be injected beneath the skin. In the operation of curetting lupus and similar growths stronger solutions (10 per cent.) are advised. The influence of cocaiue upon the cornea, causing drying and roughening of its epithelium, may be partly avoided by keeping the lids closed after each instillation. Some surgeons prefer to use gelatine discs impregnated with cocaine instead of the solution. Operations upon the Eyelids. Epilation of the Eyelashes.—Removal of the lashes is per- formed with forceps, known as cilium forceps. Fig. 162. Cilium forceps. The patient being seated in good light the operator with the ringers of one hand puts the lid upon a streteh, at the same time slightly everting its border. The faulty cilia are firmly seized and pulled out with a quick motion. After those which are readily seen have been
