�APPENDIX. [C. The comenting lime-stone in the rock ? this island, is very like ?ome of the more eompact portions of the stone of Ouadaloupe, which contains the human skeletoas, the hardaess and fi?tcture being nearly the same in both. The chief difference of these rocks seems to arise from the na- ture of the comented subetancos ;?which, in the Ooada= loupe stone, being themselves calcareous, am incorporated, or melted as it were, into the coment, by insensible gra- dation*; while the quartzose sand, in that of Dirk Harto?'s Island, is strongly eontrssted with the calcareous matter that surrounds itt. But, wherever the imbedded fragments in the !aiter consist of lime-stone, their union with the coment is eomp!ete.
