The Biology of the Blood-Cells with a Glossary of Hematological Terms. For the Use of Practitioners of Medicine
Journal of the American Medical Association
In this small volume the authors have succeeded in presenting the essential known facts of this important, and at the same time difficult, branch of ophthalmology. A great deal has been written on this subject, and in this book the authors have not presented any new facts or proposed any new theories, but have endeavored to group the facts which are absolutely necessary for the correct understanding of oculomotor affections, particularly those which are apt to be overlooked by the general
... tioner, as a correct analysis of the various forms of oculomotor disturbances is of the highest importance in diagnosing the different diseases of the brain and nervous system. Not the eyes alone but the entire nervous system must always be taken into account in oculomotor affections. After a brief summary on the fundamental laws governing the normal eye movements, with the anatomy and physiology of the ocular muscles, a few pages are given to the practical application of prisms, and the remainder of the book is devoted to the pathology of the different forms of oculomotor disturbances with their symp¬ toms and diagnosis. Contrary to the method usually adopted in text-books, of enumerating the various diseases and then describing their symptoms, the authors have done just the reverse, beginning with the symptoms and then leading up to the disease which causes them. It is really thus, as the authors state, that the problem presents itself to us in prac¬ tice. The patient does not come with the name of his disease, asking for the symptoms ; he relates his symptoms and we should from them diagnose the disease and deduce the nature and seat of the lesion. The section on the differential diag¬ nosis of paralysis of individual ocular muscles is admirably stated. The classification of the different rotations of the eye as brought out by the double images is easily compre¬ hended, especially if one has familiarized himself with Duane's table. The latter part of the book, which deals with the seat and etiology of the oculomotor affections, gives the essential facts of each case, so far as they are known, clearly and briefly. The authors are to be congratulated on having given to the busy ophthalmic surgeon this multum in parvo, which will serve him, as they say, not as a hand-book, but rather as a handy book. Principles of Surgery.
