The outerlayer of the choroid, including the large vessels, is well PLATE XIII. Fig. 8 illustrates Mr. R. Affleck Grreevess paper on A Contri-bution to the Study of the Microscopical Anatomy ofOcular Syphilis, illustrated by Three Cases (p. 277). Fig. 8.—Shows a mass of fibrillar tissue between choroid and retina,on the surface of the intact membrane of Bruch. The dark areas in themass are tubes of pigment epithelial cells. Fig. 1 illustrates Dr. Grunjiro Komotos paper on The Patholo-gical Anatomy of the Retina and Choroid after Completeand Partial Removal of their respective Blood Supplies(p. 295). Fig. 1.—Eetina and choroid near the optic disc. The retina isreduced to a swollen necrotic mass. The choroid shows great pigmentdegeneration, the chromatophores being changed into round masses ofpigment. Ophth. Soc. Trans. Vol. XXXV. Plate XIII.

Except in the areajust mentioned, the choroidal pigment is fairly wellpreserved. The inner layers of the choroid, on the other hand, aremuch altered. The chorio capillaris is only recognisablein isolated patches, and then only as a few scatteredcapillaries; in places there is a little new fibrous tissuepresent in the choroid, but not to any marked degree.The membrane of Bruch is for the most part intact, it isdestroyed, in the part immediately surrounding the opticdisc, and is broken through just behind the ora serrata. The retina is for the most part adherent to the choroid,it is extremely atrophic, and in inany places no trace ofthe original arrangement of its layers can be made out.The rods and cones have entir
