The nucleus of the city is built on a ridge of rock (Mount Sceberras) which runs like a tongue into the middle of a bay, which it thus divides into two harbours, the Grand Harbour to the east and the Marsamuschetto to the west, which are subdivided again by three other peninsulas into creeks.
The Ismdo-Malayan sub-region includes the Indian and Malayan peninsulas, Cochin-China and southern China, the Malayan archipelago, and Philippines, with New Guinea and Polynesia, excluding the Sandwich Islands.
If the continuous, unbroken, horizontal extent of land in a continent is termed its trunk,' and the portions cut up by inlets or channels of the sea into islands and peninsulas the limbs, it is possible to compare the continents in an instructive manner.
Small peninsulas are known as promontories or headlands, and the extremity as a cape.
On the south the coast-line is far more irregular, the Arabian Sea, the Bay of Bengal, and the China Sea reaching about to the northern tropic at the mouths of the Indus, of the Ganges and of the Canton river; while the great peninsulas of Arabia, Hindostan and Cambodia descend to about 10° N., and the Malay peninsula extends within a degree and a half of the equator.
