Popis: | In 1908 Mr. R. H. Worth described a number of stones which had been dredged by Mr. T. R.

These stones included a great variety of rocks such as granites, felsites, diorites, and other igneous rocks, gneisses, schists, slates, and quartzites, Devonian grits, Permian conglomerate, Triassic marl, sandstones of different kinds, Liassic limestones, hard chalks, and flints. |
