Dr. Boeckmann has introduced, in the treatment of the nodules growing into the cornea, the division of the cornea in front of the nodules; through the scar formed by the healing of the wound, they hardly ever grow. We have seen such a case in which, on the one side of the scar, no actual nodules, but only a clouding appeared, and we were later able to examine the eye anatomically. The nodule reached like a rampart close up to the scar, and all its cells were full of bacilli. On that side of the scar in the clouded part of the cornea, there were found only a few scattered cells containing bacilli; no vessels had penetrated the scar, and only a very few cells had succeeded in making their way through. The treatment is therefore a very desirable one in order to preserve the pupil free. We have been able to prepare no bacillary preparations from the _retina_, as we have not seen the affection since the discovery of the bacilli; the two brown clumps which are figured in _Plate VII, Fig. 3_, lay in the outer granular layer of the retina. As already indicated, the testicles are affected with leprosy in all nodular cases. The affection is both inter-tubular and intra-tubular. In a testicle only slightly affected, we found bacilli everywhere in the endothelium of the vessels, and in several dilated vessels white blood corpuscles filled with bacilli (_Plate X, Figs. 5_ and _6_); and in some places also bacilli lying free between the red blood corpuscles (_Plate X, Fig. 7_). At the same time, and especially where the affection is more marked, the bacilli penetrate into the seminal canals, and lie grouped in their walls around the nuclei (_Plate IX, Figs. 4_ and _5_, _Plate X, Fig. 1_), and their epithelial cells are more or less filled with them (_Figs. 1, 2_ and _4_).
