harbour which he calls Carnley's Harbour, and the three others all having confined their remarks to the northern or Laurie Harbour, we had but an imperfect notion of the entire group, even as regards its dimensions, until the recent visit of Captain Musgrave.

From the cursory examinations made by Mr. Enderby, it would appear that the island must be considerably broader than is represented on D'Urville's chart. Of course the very imperfect sketch given by Bristow cannot be taken as giving a correct idea of the island.

The following imperfect notices of the group are collected from the Narrative of the 'Voyage of Discovery, &c., of H.M.S. "Erebus" and "Terror,"' vol. I.; the 'Narrative of the United States Exploring Expedition,' vol. II.; 'Le Voyage de "L'Astrolabe" et "La Zelée,"' par M. Dumont d'Urville; and the 'Narrative of Four Voyages,' by B. Morrell. These sources have been also combined in a brochure, by C. Enderby, Esq., F.R.S., 'A Short Account of the Auckland Islands,' &c., London, 1849; and see also the 'Quarterly Review' for June, 1847.

Mr. McCormick, the naturalist to Sir James Ross's Antarctic Expedition, remarks that the formation of the Auckland Islands, as well as Campbell Islands, is volcanic, and constituted chiefly of basalt and greenstone. He also calls attention to Deas Head, in Laurie Harbour, north of Shoe Island, as being of great geological interest, exhibiting fine columns 300 feet high, which are highly magnetic. The loftiest hill, Mount Eden, at the head of Laurie Harbour, attains an elevation of 1,325 feet, is rounded at the top, and clothed with grass to its summit. Another hill in the west rises to nearly 1,000 feet.

Productions.—Dr. Hooker, whose observations have been published in connection with the voyage of the 'Erebus' and 'Terror,' under the title of 'Flora Antarctica,' remarks that, 'Perhaps no place in the course of our projected voyage in the Southern Ocean promised more novelty to the botanist than the Auckland Islands.
