Die Ophthalmologische Physik, und ihre Anwendung auf die Praxis

Abstract

THE advances in the department of Ophthalmology have of late years been so rapid and important, that either thoroughly-revised editions of the standard works or altogether new books have become a sheer necessity. The volume before us comes under the latter category, and is the work of a gentleman well known as an able physicist. The present part is occupied with the Dioptrics of the Eye; the defects in it that are due to spherical and chromatic aberration; the terminology employed to indicate the different functional relations of the several parts to one another and to light, as æquatorial, median, and sagittal planes, axes, visual lines, field of vision, angle of elevation, &c.; the principles of perspective and of the construction of the microscope, the ophthalmoscopic investigation of the eye, and the adaptation of convex and concave lenses for hypermetropia or myopia, and lastly, a section on light and colour. The parts we have read appear to be clearly and intelligibly given, and with something like French method and order. The mathematical formulæ introduced are not beyond the comprehension of an ordinary well-instructed reader, and the diagrams are numerous (123 in number) and instructive.
