Much of the information acquired in our journeys will be found in the several chapters which describe them, and which the various sections of the map are intended to illustrate. It will suffice therefore here to indicate the general structure and character of the island. The navy-surveys show that the island of MADAGASCAR has a length of 818 geographical miles, measuring from Cape Ambro on the north to Cape St. Mary’s on the south. The position of the former is in lat. 12° 2′ S.: that of the latter is lat. 25° 40′ S. The greatest breadth of the island from Cape St. Andrew to Tamatave is 354 miles: the longitudes of these two points being, long. 44° 30′ E. and long. 49° 28′ 30″ E. respectively. These longitudes have been fixed by reference to the Observatory in Cape Town. The island is a long oval, pointed at the northern end; and its major axis lies in the direction of N. 16° E. While a crevasse and channel of great depth separate it from the continent of Africa, the Farquhar Islands, at its north end, the Séchelles with their red clay, and the coral reefs in the Indian Ocean seem to me to connect its granite hills with the Laccadive and Maldive Islands and with the mighty forces which in Southern India threw into their present position the Nilgiri and Kunda hills. The island was probably the noblest portion of some great continent which stretched away from Hindustan to the south-west; and which shared in the tropical flora and fauna of India in an early stage of the earth’s history, and was separated from it while both were still young.
