On the posterior surface ofthe cornea here and there occur small nodules of endothelialcells. Several small tubercles are seen in the vitreous humor inthe vicinity of the ora serrata. These are made up of branch-ing cells and are surrounded by capsules of young connectivetissue. Some are slightly infiltrated with pus-cells, but theyshow no caseation. The elevated spots in the fundus are found to be tuberclessituated between the choroid and retina and involving bothof these structures (Fig. 7). The rods and cones, and to aless extent the nuclear layers, are replaced by a caseous mass. i^ig- 1-—Experiment 2. Sclerokerati-tis due to dead bacilli introduced into vit-reous of rabbit. Note also minute tu-bercle on membrane of Descemet.
