Book excerpt: Excerpt from Lectures on the Errors of Refraction: And Their Correction With Glasses, Delivered at the New York Post-Graduate Medical School, Illustrative Cases From Practice, Both Private and Clinical These lectures to the physicians who attended the section on Diseases of the Eye, at the New York Post-Graduate School, having been received by them with many words of approval, and also with the request that I would publish them, are my reasons for now offering this work upon the "Errors of Refraction" to the profession. I know that many text-books treat this subject in perhaps a more scientific manner than it is here presented, but I have endeavored to make this work as simple and practical as possible. The methods of testing for and prescribing glasses, as herein described, are so simple that they can be readily understood even by one who is not familiar with the science of ophthalmology; and are so written that they will be of service in the hands of the general practitioner, who has too little time to devote to the study of the larger works on Refraction. I believe that there are some subjects which I have discussed that will also be of value to the specialist, in the work of correcting the errors of refraction; as in the lectures on retinoscopy and astigmatism, and in the diagnosis of refraction with the ophthalmoscope. I am indebted to my friend and teacher, Prof. D. B. St. John Roosa, for many of the practical points in these lectures, and likewise for almost all my early teachings on this subject.
