So much of general as well as special interest is to be learned from the examination of the fundus oculi that no physician nowadays is fully equipped for his work who cannot use the ophthalmoscope. This little hand-book, which can easily be carried in one's coat pocket, is intended for the use of the beginner in ophthalmoscopy and fulfils its purpose well. One finds much more mathematical optics than is necessary for a practical understanding of the use of the instrument, but the very lucid anatomic and pathologic descriptions will be a great aid to the student in the comprehension of what he sees. There are twenty-eight colored plates showing fifty-five fundus pictures, each accompanied by a case history. While some of the pictures are a little sharp and glaring, they are, as a whole, wonderfully true to nature, and much better than those frequently found in more expensive manuals.
