Proceeding westward along the great volcanic chain of the East Indian Archipelago, _Solor Strait_ is represented in a chart published by Dalrymple from a Dutch MS., as fringed; as are parts of _Flores_, of _Adenara_, and of _Solor._ Horsburgh speaks of coral growing on these shores; and therefore I have no doubt that the reefs are of coral, and accordingly have coloured them red. We hear from Horsburgh (vol. ii, p. 602) that a coral-flat bounds the shores of _Sapy_ Bay. From the same authority it appears (p. 610) that reefs fringe the island of _ Timor-Young_, on the N. shore of Sumbawa; and, likewise (p. 600), that _Bally_ town in _Lombock_, is fronted by a reef, stretching along the shore at a distance of a hundred fathoms, with channels through it for boats; these places, therefore, have been coloured red.—_Bally_ Island. In a Dutch MS. chart on a large scale of Java, which was brought from that island by Dr. Horsfield, who had the kindness to show it me at the India House, its western, northern, and southern shores appear very regularly fringed by a reef (see also Horsburgh, vol. ii, p. 593); and as coral is found abundantly there, I have not the least doubt that the reef is of coral, and therefore have coloured it red. JAVA.—My information regarding the reefs of this great island is derived from the chart just mentioned. The greater part of _Maduara_ is represented in it as regularly fringed, and likewise portions of the coast of Java immediately south of it. Dr. Horsfield informs me that coral is very abundant near _Sourabaya._ The islets and parts of the N. coast of Java, west of _Point Buang_, or _Japara_, are fringed by reefs, said to be of coral. _Lubeck_, or _Bavian_ Islands, lying at some distance from the shore of Java, are regularly fringed by coral-reefs. _Carimon Java_ appears equally so, though it is not directly said that the reefs are of coral; there is a depth between thirty and forty fathoms round these islands. Parts of the shores of _Sunda Strait_, where the water is from forty to eighty fathoms deep, and the islets near _Batavia_ appear in several charts to be fringed. In the Dutch chart the southern shore, in the narrowest part of the island, is in two places fringed by reefs of coral. West of _ Segorrowodee_ Bay, and the extreme S.E. and E. portions are likewise fringed by coral-reefs; all the above-mentioned places coloured red.
