Keratoma 5.

4. KERATOMA.

In our nomenclature the terms 'Keratoma' and 'Keraphyllocele' are both used to indicate the condition we have just described.

There are some, however, who reserve the term 'Keratoma' for horny tumours occurring only on the sole, and for that reason we draw special attention to the word here.

Keratoma may thus be used to describe what we have called keraphyllocele directly that growth makes its appearance at the sole, and is there able to be cut with the knife.

Keratoma probably offers us the best analogy we have to corn of the human subject.
