    DESCRIPTION OF THE PLATES Illustrating Mr. Bader’s Description of the Human Eye in Health and Disease as seen by the Ophthalmoscope. Fig. 1. Right eye. Fig. 2. Left eye. From a patient, set. 17, suffering severely from inherited syphilis. Both eyes eighteen months ago were impaired by corneo- iritis j both at present are what is termed hydrophthalmic; there exists bare perception of shadows of the left, high degree of weak and of short sight of the right eye. The left eye had been defective as long as the patient remembers. Fig. 1. The yellowish-pink round optic disc (optic nerve) (represented much enlarged) occupies the middle of the figure; diverging from its clear centre we observe numerous retinal arteries and veins (the darker vessels represent the veins). Surrounding the optic disc we see a white figure (the sclerotic, seen through the atrophic choroid and transparent retina). A brownish-black line of pigment intervenes between this white figure and the red colour of the choroid. The latter, near the white figure, has a much lighter red tint, indicating a thin— somewhat atrophic—condition of the choroid. In the red choroid we observe a peculiar network of darker red lines (closer set patches of capillary blood-vessels of the choroid). Fig. 2. Left eye. The optic disc, in the middle of the figure, differs, as regards colour, from the one of the right eye (fig. 1); it appears grey (anmmic) with a clear centre. The retinal vessels, which diverge from it (especially the arteries), are less numerous than in the right eye, while the retinal veins are very varicose, probably owing to morbid changes in the optic disc, giving rise to impeded in- and egress of blood. As regards the white figure round the optic disc, the pigment, the varieties of red colour of the choroid, the same holds good as for fig. 1. Figs. 3 and 4. From the left eye of a person, set. 33, suffering from secondary syphilis. The pupil of this eye was sluggish, somewhat dilated; there were no outward signs of inflammation; with this eye large objects could he recognised with difficulty. The right eye had suffered from repeated attacks of iritis. Fig. 3. The optic disc (optic nerve) and the tunics immediately adjoining it. The somewhat oval-shaped optic disc occupies the middle of the figure; its grey colour is of a lighter tint in the centre (where there are no nerve-fibres, but only connective tissue). The disc is surrounded by a yellowish ring, which shades off into the red colour of the choroid. Diverging from the optic disc, we observe the retinal blood-vessels; some of these are unequally dilated; others, owing to im- paired transparency of the retina, are barely visible in some places. The two yellowish, round, somewhat ill-defined spots, to the left of the optic disc, are supposed to be nodules of lymph, situated in the choroid; a retinal blood- vessel may be seen passing over them. The group of black and yellow spots above and to the right of the optic disc represents atrophic portions of choroid. Fig. 4. A portion of the sclerotic, choroid, and retina of the eye represented in fig. 3. The yellowish, somewhat ill-defined, small round spots, seven in number, are supposed to be nodules of lymph, situated in the choroid. The yellowish spot in
