Summary

The following account of recent discoveries of sunken rocks in the neighbourhood of the Philippines, though they have been reported to the Admiralty, and do not possess any general interest, yet seem to deserve a place in the publications of the Hakluyt Society.

A rock was discovered in the Sulu seas by the Spanish steamer Magallanes, commander Don Miguel Lobo, on the 3rd July, 1849. It was on a level with the surface of the water, and surrounded by breakers on the Takút Pabúnúwan Bank, the least depth of water on which, according to Horsburgh, is three fathoms, and six according to Captain Dalrymple's chart. “It is a rock of an elliptic figure, distant seventeen or eighteen miles from the southwest part of Pilas; is nearly on a level with the water, but it showed a little above water at the time it was examined: soundings nine to twelve fathoms all round it at a boat's length from the breakers; three or four fathoms further off no bottom with twenty-five fathoms Bearings N.E. islet of Duo Bolod S. 65° E. S.W. islet of Duo Bolod S. 61° E., the island of Vitinan S. 15° E.; and the centre of the most northern part of Pilas Island N. 38° E. Rock in latitude 6° 17′ north, and longitude, according to Capt. Dalrymple's Chart, 127° 31′ E. of Cadiz. It is situated three miles from the N.E. part of the bank described by Horsburgh. We steered from it S.W.¼W. for about three miles, and found ourselves in shallow water, and sounded successively 11, 7, 6, 5½ 5, and 4 fathoms of water.”
