    XI. An Investigation into the Functions of the Occipital and Temporal Lobes of the Monkey s Brain. By Sanger Brown, M.D., and E. A. Schafer, F.R.S., Jodrell Pm&ssor of Physiology in University College^ London.* Received November 24,—Read December 15, 1887. [Plates 48-50.] The experiments which we here record were performed during the precedfk^Vmter and spring in the physiological laboratory of University College, but their formal publication has been hitherto deferred because we were desirous of keeping some of the animals in which the lesions had been established under observation during several months, in order that any modification which that lapse of time might produce in the symptoms should be duly recorded. But, although not hitherto published, several of the cases, while still under such observation, have been brought before the notice of both the Physiological and the Neurological Society of London, and have been examined at different times by various persons interested in the subject of cerebral localisation, besides being familiar to the regular workers in the laboratory. In this way we have repeatedly had the opportunity of showing most of the symptoms which we are about to record, nor have we inserted any detail as to the accuracy of which there could, to an unbiased mind, be the slightest doubt. All our experiments have been performed with the view of establishing certain lesions, uni- or bi-lateral, embracing definite areas of the cerebral cortex ; and they have been confined, or nearly so, to the occipital and temporal lobes. In the perfor- mance of the operations strict antiseptic precautions were employed, the dressings being fixed by a collodion cap. On the fourth or fifth day after the operation this cap * I desire to acknowledge the assistance T have received, both from the Association for the Advance- ment of Medicine by Research and from the Government Grant Fund of the Royal Society, in aid of this series of researches. By a grant obtained from the Association many of the expenses attendant upon the procuring and keep of the animals have been met, while the Government grant has enabled me to secure the services of an able assistant (Mr. B. P. France), who has devoted a large part of his time to a careful ]post-mortem investigation of each case, with a view to the precise determination of the extent of the lesion, together with consequent degenerative changes in other parts of the central nervous system. The latter part of Mr. France’s work must necessarily still occupy a considerable time, and any results which it may yield will be the subject of a future communication.—E. A. S.
