The cornea is liable to ossification. Wardrop saw a ease in which the wholeeye had changed its form,and the cornea contained a hard, smooth, oval plateof bone, weighing two grains. A piece of bone was also found between thechoroid coat and the retina of the same eye.* In another case, referred toby Voigtel, a German author,! a piece of cornea, taken from a man sixty * Morbid Anatomy of the Eye, vol. i., p. 74.

It was three lines long,two broad, and weighed two grains. A still more remarkable example is re-ported by Dr. Monet, in the Nouvelle Bibliotheque Medicale, for May, occurred in an old man, and the cornea is said to have been ossified through-out. This transformation is by no means so frequent as the cartilaginous, ofwhich a considerable number of instances are related by authors. Fleshy excrescences have been seen on the cornea. They are occasionallyof a fungous character, and in several instances they have been found to con-tain hairs. These morbid growths appear to have their origin, for the mostpart, on the conjunctival covering of the cornea. Alterations in the form of the cornea occur under two principal varieties,the conical and the spherical, which, as they arise from different causes, re-quire to be considered separately. The conical variety (Fig. 112) is some-times congenital, or begi
