Excerpt from On the Use of the Ophthalmoscope in Diseases of the Nervous System and of the Kidneys: Also in Certain Other General Disorders Some considerable parts of the present volume have already been published. I may refer more especially to my paper upon the 'Optic Nerves and Retinas of the Insane, ' which appeared in the volume of Transactions of the Medical and Chirurgical Society for 1868; to an article on Medical Ophthalmoscopy, which appeared in the number of the British and Foreign Medico-Chirurgical Review' for January, 1868;to some lectures on 'Optic Neuritis, ' which appeared in the Medical Times and Gazette between the 9th of May and theist of August, 1868, inclusive; and to some papers on the use of the Ophthalmoscope in tubercular meningitis and in spinal disease, which appeared in the Lancet of May 1st and May 8th, 1869, and of January 15th, 1870. Little or nothing, however, has been transferred to this book as it stood. I have found it necessary to revise the whole, and to re-write large portions, in order to add the results of more experience and to express maturer opinions. Thus a great part, the far greater part indeed of this volume, is now issued for the first time; and its pages might have been almost indefinitely multiplied had I thought it right to use all my accumulated material, and to publish a large number of cases.
