    (i as if they were nuclei. When the epithelial surface of thr distal side of the cornea is inspected, the layer of cells is from 7 to 10 cells deep near the wound, and they lie not only flat- wise, but obliquely, and in some cases almost perpendicularly to the surface of the cornea, and cannot be distinguished in form from those which occupy the intercalary plasma or callus of the wound. That portion of the cut of section 3 into which the iris penetrates has been opened by the slight withdrawal of the iris from contact with the borders of the cut, and the tip of the prolapse is covered by a pointed mass of rounded, oval, elongated and variously shaped cells imbedded in a homogeneous material. At this region the substance of the cornea is spongy, opened out by the separa- tion of the laminas, and very few lymphoid cells appear, while the corneal corpuscles are rather numerous. At this point, too, a small quantity of lens matter is found between the iris and the corneal cut. On the posterior surface of the proximal iwrtion of the cornea, in section 3, the epithelial cells of the posterior elastic lamina are numerous and distinct. In sections 4, 5, 6, 7, 8 and 9, it is on the proximal side of the cut that the epithelium takes on special activity. In section 10 it is jDretty equally divided between both sides. In section i the epithelial activity is decidedly greater upon the distal side of the cut, and the cut itself is filled with a large mass of new-formed material apparently composed of lymphoid cells exclusively, and at one point these cells break through the epithelium just below the cut. In section 2 the epithelial activity is also greater upon the distal side of the cut, and lymphoid cells seem to be forcing their way through the epithe- lium of the surface, and the cornea below the epithelium on both sides of the cut is dotted with lymphoid cells. These grow less numerous as one approaches the posterior surface of the cornea. In section 4 the intense activity of epithelium is found on the proximal side of the cut, and in this region the corneal activity is especially noteworthy on this side and defi- cient on the other side. In section 5 the epithelial activity is very great on the proximal side and almost wanting on the distal side,
