 M. Pholadis, and M. rugosus, the two former penetrating madrepores,

 operation, this tribe, at least, might be considered as producing 

 that eifect by a chemical solvent, which, as the substances acted 

 upon were calcareous, was probably an acid ; although he admitted 

 that the action of tests had not made the presence of such secre- 

 tion satisfactorily apparent, — recommending a prosecution of obser- 

 vations and experiments, as the subject had excited much attention.
