II. On the Indications for Operative Treatment, and on a New Operation, "Keratectomy," after severe Injuries of the Eyeball; with cases. By W. SPENCER WATSON, M.B., F.R.C.S., Surgeon to the Royal South London Ophthalmic, and to the Central London Ophthalmic Hospitals. (Received May 30th, 1871.) (Abstract.) In the case of penetrating wounds the occurrence of glaucomatous symptoms is shown to be the most urgent indication for operative treatment, viz. either linear extraction or iridectomy. At a later stage, after the subsidence of the acute symptoms, iridectomy may be required, or the removal of the cataract indicated; and these operations are most likely to be successful when all signs of active congestion have disappeared. Cases in illustration are given. The prospect of the complication of sympathetic ophthalmia is always possible when the stage of congestion with pain and photophobia is much prolonged, and whenever a foreign body is left in the injured eye. Under these circumstances the removal of the injured eye is sometimes necessary. But if constitutional treatment can be properly carried out, the removal of the injured eye may be postponed or altogether averted. A case in illustration is here given. In traumatic and idiopathic cases of suppurative ophthalmitis the operation of keratectomy is proposed, and in one case has been performed successfully by the author. Its object is to establish a fistulous opening in the cornea, through which the morbid products of the inflammation may escape freely until such a time has elapsed that the tissues may have recovered. It is suggested that in some cases of threatened suppurative ophthalmitis keratectomy might prevent the anticipated mischief. III. The Modifications produced on the Temperature of the Body by the local application of cold and heat. By FREDERICK BARHAM NUNNELEY, M.D. AssistantPhysician to the City of London Hospital for Diseases of the Chest, and to the Hospital for Sick Children. (Received May 30th, 1871.) (Abstract.) Experiments detailed in this paper have yielded the following results : any 1. That immersion of one extremity in iced water did not cause alteration in the temperature of the other extremities or the body generally, unless the subject of experiment was in a state of more or less nervous exhaustion, or there was decided coolness of the surrounding air, when a fall of temperature occurred. 2. That a slight rise of temperature in the body generally, and a more considerable one in the extremities, followed immersion of a hand or foot in water hotter than the blood, amounting under the tongue to about 1° F., and in the extremities to 1° to 3° F., above the normal standard, and that— 3. If at this time any one of the extremities was put into cold water, a fall of temperature below the normal, slightly marked in the body generally, and much more so in the extremities very shortly commenced. If the hand or foot was now withdrawn from the water, reaction became established, and the natural temperature was slowly attained. Such results would appear to show that for cold to act locally a disturbance of the conditions which maintain the normal balance of temperature is necessary first of all, viz. such as is caused by undue heat, and they suggest the idea that these variations of temperature may be regarded in many respects as parallel to those attending a slight rigor, and that they are not always the result of reflex agency. IV. On a Simple Method of removing Silver Wire when employed in cases of Ununited Fracture. By FRANCIS MASON, F.R.C.S., Assistant-Surgeon to St. Thomas's Hospital. (Received June 13th, 1871.) (Abstract.) The object of the paper is to describe a plan of fastening the broken fragments with a needle and a loop of wire so arranged that in withdrawing the needle the loop of wire is released, and thus may be removed without pain to the patient, and without injuring the bone or soft parts. At the conclusion of the meeting the President drew the attention of the Fellows to the intended change in the times of meeting which had been adopted at the last Anniversary, and which would commence with the next Session, viz. that the first meeting of the Society would be on the second Tuesday in October, instead of in November; and also further men tioned, that to allow of the alterations connected with the Society's Meeting Room being carried out previous to the commencement of the Session, the Library would be closed during the months of August and September.
