Excerpt from A Handbook of the Diseases of the Eye: And Their Treatment The fifth edition of this book was issued in January, 1895, and has been for some months out of print. In this edition the pages in the first chapter of former editions on Some Elementary Optics have been omitted to make room in the book for other matter. After all, it may be reasonably expected that the student will bring with him to the study of eye disease, not only a good knowledge of the anatomy and physiology of the eye, but also that acquaintance with optical laws which is required for the proper understanding of the refraction and accommodation of the eye, and of the theory of the ophthalmoscope.
