If he will now imagine that every one of these membranes is turned into stone, he will understand the formation of the madrepore's skeleton, and its relation to the soft investing flesh.
Mr. Gosse, the naturalist, to whom we are indebted for many striking facts relating to the beautiful inhabitants of the sea, has given a charming description of the living madrepore in one of his pleasant books.
