Since the unsuccessful attempt at the end of last century to extend Austrian commerce with the Indies and the coast of Africa, by founding a few colonies in those places, no vessel sailing under the Austrian flag had again visited the Nicobar Islands, and accordingly, on the dispatch of an Imperial ship-of-war to those waters, it was naturally wished that she should on her voyage to China visit this group, on whose shores the Austrian flag had once been unfurled as a symbol of possession. On this occasion, however, the object was rather scientific than political. It was intended, so far as the time allotted for visiting these islands and the appliances at hand admitted, to undertake inquiries as to the most important geodetical points, together with astronomical, magnetic, and meteorological observations, and at the same time to make investigations and collections of the various objects of natural science, and thus to complete as it were the valuable labours carried out in 1846 by the Danish Expedition to the Nicobar Islands. The following pages are simply limited to giving a popular narrative of our own stay on this interesting island group, while more circumstantial information of the various scientific results obtained there will be deferred till the appearance of the special works being drawn up by the members, each in his own special section. On 25th February, at 10 A.M., the naturalists, accompanied by the officers in charge of the scientific apparatus, and the midshipmen, after very considerable difficulty, succeeded in effecting a landing on the island of Kar-Nicobar, in a bay protected by a coral reef (by observation 9° 14' 8'' N., and 92° 44' 46'' E.), between the villages of Moose and Sáoui. At this point the surf beats incessantly over the huge reefs of coral upon a waste of gleaming white sand, which stretches in graceful curves from one point of rock to that next adjoining. The few fruits which have been thrown up, or been carried hither, probably from some distant shore, have struck root in this coral sand, and a coronal of luxuriant palms, with their slim stems, and loaded with thousands of nuts, serves as food for man.
