Excerpt from Archives of Ophthalmology and Otology, 1878-1879, Vol. 7 To stain the cornea, I at first tried nitrate of silver. The cornea of a cat was taken out immediately after death, and was put into a two-per-cent solution of nitrate of silver for one half to one hour; then it was washed with distilled water, and, finally, for several days left under the influence of a very mild dilution of acetic acid. Instead of the acetic acid, in later experiments, I substituted lactic acid, which proved even more satisfactory than the former. After being prepared in this way, the cornea of the cat was ready to be split into lamellae. The specimens were mounted with equal parts of glycerin and water.
