VERRILL.—Some very interesting specimens were recently pre- 
sented - the Peabody Museum of Yale College, by Dr 
rimble, of New These are fragments of white Italian 
marble, from a cargo wrecked off Long Island in 1871, and taken 
up this year. The exposed — of the slabs are thoroughly 
penetrated to the depth of one to two inches by the crooked and 
regular borings or galeries of the sponge, Cliona sulphurea V., 
so as to reduce it to a complete honey-comb, readily crumbling 1 in 
the fingers. Beyond the borings the marble is perfectly sound 
and unalterd. The rapid destruction of the shells of oysters, ete., 
by the borings of this sponge has long been familiar to me, 
of its effects upon marble or aac I have not before seen

tures of limestone or other similar materi
