a Scientific Intelligence. 
In structure the sponge is composed of an intertexture of granular 
matter and pin-like silicious spieule. Several species of Cliona are indi- 
eated by European naturalists, but are not characterized with sufficient 
detail to determine whether the one above indicated is distinct or not 
from them. 
. L. further added, it might appear only of scientific interest to ob- 
serve a structure so low as the sponge is classified in the organic king- 
dom, endowed with the power of penetrating such dense and hard bodies 
_as the shell of the clam and oyster, but he suspected that the agency of 
the boring sponge was a highly important one in the sequence of natural 
phenomena, as it is a means by which dead shells are rapidly decomposed 
to be dissolved in the ocean water, where they may again serve as the 
elements of construction of the habitations of the rising generations of 
molluscous animals. In confirmation of this view Dr. L. stated, that an 
extensive bed of oysters, which had been planted by Mr. Thomas Beasley, 
at Great Egg Harbor, and which was in excellent condition three years 
since, had been subsequently destroyed by an accumulation of mud. The 
shells of the dead oysters, which were of large size and in great number, 
Cliona that they may be crushed with the utmost ease, . 
the agency of this sponge the dead shells might have remained in their
