Handbuch der biologischen Arbeitsmethoden

Abstract

This portion of the work, Abderhalden's “Handbuch,” is the direct continuation of parts 3 and 41 which dealt with the biophysical methods used in investigating the living eye and its sensitivity to light. The first section, by Dr. Vogt of Basel, is devoted to the method of examining the eye with light from which the red rays have been absorbed by passage through a concentrated solution of copper sulphate and a weak solution of erioviridine. With such light, investigations of the yellow spot are rendered much easier and more accurate. Thesecond section of 76 pages,by Dr. Baslerof Tübingen, deals with methods which in the main are intended to investigate the functions of the retina and its various parts. Sharpness of vision, irradiation, and detection of movement are some of the subjects dealt with. The concluding section, by Dr. Struycken of Breda, describes the photographic method he uses for studying the movement of the eyeball from side to side. The treatment is in general more wordy than is desirable, but the work brings together in an accessible form a large amount of information hitherto buried in memoirs, published in most cases abroad.
