From The Hindu Archives, April 6, 1926: A curious operation

In an effort to save a boy’s eye, a piece of frog’s skin was grafted on the eyeball at West London Hospital. 

There is every hope that within three days the operation, which was performed by a well-known ophthalmic surgeon, will have proved effective. The piece of skin was taken from the inside of the lower jaw of the frog.

An official of the hospital explained that under the microscope the skin of the rest of the body looks rough and raised, whereas the skin covering the eyeball is the same as that of the lower jaw of the frog—flat, like a tessellated pavement.
