    Ophthalmoscopic Picture of the larger Retinal Vessels. Dr. Schnel- LER.—A long and interesting paper, illustrated by eight figures. From his injections he concludes, that the sw5-vaginal space communicates with the sitpra-vaginal by irregular openings in the outer optic sheath, and by similar openings in the sclerotic with the perichoroidal space. The latter connects by the perivascular space around the venm vorti- cosm with the Tenonhs space, so that injecting material, on the one side through the spaces of the optic sheath, on the other by the scle- rotic spaces, meets in Tenon’s space, or the supra-vaginal space imme- diately connected with it. The sub-vaginal space and the other spaces are, according to Schwalbe’s examinations, to be regarded as lymph spaces. The proof of the communication of these spaces, and their being lined with endothelium plates, go towards showing that they are the roads for the movement of the lymph. A new Method of' determining the Optical Constants of the Eije. Drs. Mandelstamii and Sciioler. Pigment Deposit in the Parenchyma of the Cornea. Dr. Hirschler.— He calls attention to certain deposits of pigment in the cornea pro- pria, which he figures, and has seen cases of: 1st, keratitis dif- fusa parenchymatosa. Iritis serosa. Pigment deposit in both eyes. 2d, keratitis parenchymatosa, episcleritis, iritis double. Pigment de- posit in left eye only. The Visible Movement of the Blood in the Retinal Vessels. Dr, Becker.—An elaborate and interesting article of ninety pages, of es- pecial value to those who are using the ophthalmoscope in general medicine. PiefiUation of the latest Objections to Graefe’s Linear Extraction. Dr. Jacobson.—This is much too long to be sketched here, and should be read carefully by all those now becoming ready to adopt Liebreich’s bold cut through the cornea, as well as those who are reporting on Graefe’s operation, which they in reality never carry out as he said it must be, to insure the success he had with it. Vide Errata in vol. xviii,. Part ii., 1812. Anatomical Examination of Tijpical Retinitis Pigmentosa. Dr. Lan- noLT.—A case which had been frequently seen during life in Professor Horner’s clinic, came under the observation, post mortem, of the au- thor, who reports his very careful histological examination, and illus- trates it with figures. Efect of Optical Glasses on the Power of Vision. Dr. Woinow.— A short article, to be studied with those of Knapp, Hock, Donders and Mauthner. Remarks on Dr. Morano^s Article on “The Nerves of the Conjunctiva.’^ Dr. Helfreich.—A criticism, to be read with Morano’s communication. Vol. xviii.. Part ii., 1872. On Keratitis. Dr. S. Talma.—This article gives the results he pub- lished last year in a communication published in Dutch, in reference to the origin of the pus corpuscles in traumatic keratitis. It was to endeavor to decide whether all the so-called pus-cells of the inflamed cornea were white corpuscles, or whether a p'krt at least were not de- rived from the substance of the fixed corneal corpuscles. The result of his study is, that all pus cells in traumatic inflammation of the cor- nea are wandered blood corpuscles. Histology of the Lamina Cribrosa. Dr. Wolfring.—He concludes
