This represents an extensive experimental work on the eyes of animals and man. The material was as fresh as possible in the human cases, as early as an hour after death. An elaborate technic was worked out for the study of the permeability of the choroid and retina as well as for the retina alone. The study was made first on the permeability of the tissues for water and for various alkaline and acid solutions as well as dyes. The permeability from within out, i. e., from retina toward sclera, as well as from without in, was estimated. The influence of various drugs was also studied. The author found that sodium iodide solution 0.04 per cent increased, atropine sulphate 1: 50,000 reduced, and pilocarpine chloride and, even more, physostigmine salicylate increased the permeability of the retina for water. The significance of these experiments for the pathology of the eye may
