Book Description
Excerpt from Physiological Optics: Being an Essay Contributed to the American Encyclopedia of Ophthalmology Through the courtesies of Dr. Casey A. Wood, Editor-in-chief of The American Encyclopedia of Ophthalmology, and the publisher, Dr. Geo. Henry Cleveland, of the Cleveland Press, the writer of this monograph has been able to secure a limited number of reprints of the original essay for the use of students and practitioners who may be interested in the field of physiologic optics. The body of the text is in the form presented in Volume XIII of the Encyclopedia. Certain references to other volumes of the set have been changed in this reprint and a few additions deemed necessary by virtue of the isolation of this essay from its context have been placed in the Appendices. The present volume is neither a mere compilation nor does it consist of abstract theoretical discussions, but is a collection of the old and new scientific facts that have bearing upon the practical work of the refractionist and eye-practitioner. I hope that the reader will pardon any indulgence in details relative to some of the topics presented, but I feel that far too little attention is paid, in many cases, to the fundamentals and essentials underlying the science of optics as applied to visual phenomena and that a closer and keener study of these vital details will help make the "practical" man of the right type. I take pleasure in acknowledging my indebtedness to various authors and publishers who have put at my disposal, through the medium of the printed page, such materials as have helped greatly to make this volume what it is. I have drawn freely from the writings of von Helmholtz, Tscherning, Maddox, Stevens, Howe and Savage. In particular do I acknowledge the permission granted by the Editor and the Publisher of The American Encyclopedia of Ophthalmology, The Keystone Publishing Co. of Philadelphia, Dr. Savage, Dr. Howe, Dr. Stevens and Chas F. Prentice, M. E., to have reproduced, or to use the original cuts of, several diagrams and drawings from their books.
