    PLATES VI & VII (continued). Pig. 8. —a and n. Two ultimate branches of two different nerve-trunks, from the cornea of the frog, showing very distinctly the precise manner in which the one branch anastomoses with the other. The anas- tomoses are effected by the mutual change of the fibres. X 350. 9. —Prom the cornea of the frog. Bundles of nerve-fibres, forming networks. Connected with them may be seen a triangular body, from which fibres proceed in different directions. Some fibres of the bundles pass close to this body without any intimate connec- tion with it. The triangular body contains granular matter, which appears to have collected in two places, assuming the appearance of two dark spots. X 350. 10. —Triangular body, from which fibres spring in three different directions. Prom the cornea of the frog. X 350. 11. —Network of pale nerve-fibres, and network of the branches of the cornea-corpuscles, from the cornea of the frog. These two kinds of networks lie on different planes, and the relation between them is well shown, x 350. - 12. —Shows the course, size, and relative position of the primitive nerve- fibres in the branches of the nerves distributed to the cornea of the mouse. X 350. 13. —Nervous plexus in the cornea of the mouse. The general arrangement of the bundles of nerve-fibres in the formation of the plexus, and the special bodies connected with them, are well seen. X 250. 11.—One of those special bodies which are seen in connection with the nervous plexus of the cornea of the mouse. Besides a nucleus, it contains granular matter. Bundles of fibres proceed from it in three different directions, x 350. 15.—Another body of the same kind, in which the nucleus has undergone division. Prom the cornea of the mouse, x 350. 10.—Prom the cornea of man. Small nerve-branch, which divides into two smaller ones; and from the pressure to which the thin section of the cornea has been subjected, the nerve-fibres of one branch ap- pear separated from one another, x 350. 17.—Shows the manner in which the fine bundles of nerve-fibres are arranged in the formation of the plexus existing in the human cornea, x 350.
