| It occurs in the Dublin limestone, and resembles a coral or madrepore. |
| One need only glance at the photographs of osmotic productions to recognize the forms of madrepore, fungus, alga, and shell. |
| All around is a sea of mounds covered with sand, where the houses stood, mostly built of madrepore, and laid out in streets. |
| Constructions in madrepore resist rather well the seisms, frequent but with low intensities in the region. |
| The madrepore corals are called reef-builders, but not in the sense of constructors of reefs. |
| The madrepore pier had been nearly swept away, and the houses near the water were flooded. |
