    Description of Mr. Bader^s Plates—[continued). the centre, and the one at the lower margin of the figure with brownish-black spots upon it, represent atrophic portions of choroid. Previous to this, lymph and infiltration are supposed to have occupied these parts of the choroid. Rami- fying over these spots and over the uniform turbid red colour of the choroid, we notice blood-vessels of the retina ; some, especially those over atrophic portions of choroid, are abnormally large. In the choroid to the right of the figure we see a large blood-vessel, and along its sides a yellowish line, which may be lymph. Fig. 5. Left eye. From a person, set. 11, sutfering severely from inherited syphilis. Both eyes were large—“ hydrophthalmic ”—and had suffered from corneo-iritis. There was partial loss of sight. The figure represents the optic disc (optic nerve) and the tunics immediately adjt^iuing it. The light grey blue (aummic), somewhat oval-shaped optic disc occupies uhe centre of the figure; diverging from it we see the blood-vessels of the retina; their number and calibre, considering the age of the patient, are much below par. The narrow yellowish-white ring round the optic disc—somewhat ill-defined where it joins the red colour of the choroid—is observed in most eyes in which choroidal changes, with inflammation, have occurred. The yellowish- white and the black spots represent atrophic portions of choroid. Fig. 6. Right eye. From a patient, set. 34, who suffered from secondary syphilis; pupil sluggish, of medium dilatation; no outward sign of inflamma- tion ; bare perception of shadows. The ill-defined grey-white part in the middle of the figure represents the optic disc (optic nerve) and the tunics immediately adjoining it. Diverging from the middle of the grey-white part we observe few thin retinal blood-vessels. Their outlines are very indistinct where they pass from the grey (infiltrated opaque retina) upon the red (transparent retina, subtended by red choroid) portion of the figure. Infiltration, swelling, and loss of transparency are the cause of the altered colour and of the loss of defineduess of the optic disc and adjoining tunics. Fig. 7. Right eye. From a patient, mt. 49, suffering from secondary syphilis ; had iritis in both eyes; bare perception of shadows. The dirty red, ill-defined sketch, occupying the middle of the figure, represents the optic disc (optic nerve) with a narrow strip of the tunics adjoining it. No defined retinal blood-vessels, no details of the surface, boundary, &c., of the optic disc are visible; this is owing to infiltration and to concomitant morbid changes of the choroid, retina, and of the adjoining vitreous substance. Fig. 8. Right eye. From a patient, set. 47, suffering from secondary syphilis ; pupil sluggish, medium dilatation, no outward inflammation; perception of large objects. Had iritis in the left eye. The optic disc (optic nerve) (represented much enlarged) occupies the middle of the figure. The greyish-red ring defines its outline; the optic disc, compared with the red colour of the choroid, has a lighter turbid red colour. Diverging from it we observe a few retinal blood-vessels; their outlines, owing to impaired transparency of the adjoining structures, are indistinct. The choroid (the red surface which surrounds the optic disc), instead of having a clear transparent red colour, appears turbid red; this is owing to impaired transparency—from chronic inflammation—of the choroid, of the retina, and of the adjoining vitreous sub- stance.
