In June 1793, Messrs. Bampton and Alt, in the English merchantships Hormuzeer and Chesterfield, got embayed on the south-east coast of New Guinea, and after in vain seeking a passage out to the north-east, were forced to abandon the attempt and make their way to the westward, through Torres Strait, which they were no less than seventy-three days in clearing. Among other hydrographical results, was the discovery of large portions of the land forming the north-west shores of this bay, extending from Bristow Island to the northward and eastward for a distance of 120 miles.
M. RUALT COUTANCE.
In 1804, M. Rualt Coutance, commanding the French privateer L'Adele, made several discoveries on the south-east coast of New Guinea which were recorded by Freycinet, from the manuscript journal of Coutance, in the history of Baudin's voyage.* A portion of this is unquestionably the land seen by Captain Bligh in 1792--but in addition detached portions of the shores of the great bight of the south-east coast were seen, as in the neighbourhood of Freshwater Bay and elsewhere.

Mr. Bristow, the master of an English merchant vessel, visited the northern part of the Louisiade Archipelago in 1806, but added nothing of consequence to our knowledge of the group, although various islands were named anew, as if discoveries of his own. His Satisfaction Island is clearly Rossel's, and Eruption Island is St. Aignan's of D'Entrecasteaux.*

CAPTAIN DUMONT D'URVILLE.
Since Bougainville's voyage the southern shores of the Louisiade remained unvisited until the year 1840, when Captain Dumont d'Urville, with the French corvettes L'Astrolabe and La Zelee, during his last voyage round the world, determined upon attempting their exploration. On May 23rd, the expedition (coming from the eastward) rounded Adele Island and Cape Deliverance, at the distance of about twenty miles. Next morning, the thickness of the weather prevented them from clearly distinguishing the features of the land. They steered towards South-east Island, but found close approach prevented by an immense continuous reef, supposed to be part of that seen on the previous day to the southward of Rossel Island. On Conde's Peninsula, some natives and a small village were observed. In the evening a long line of islands (the Calvados group) appeared to the north, and the reef, which before had been continuous, with the exception of some small openings, now existed only as a few isolated patches. D'Urville stood off to sea for the night, and next morning passed close to some low woody islets (Montemont) enclosed by a reef stretching to the eastward, and supporting upon it many scattered islands covered with verdure. Bougainville's chart was found of very little assistance; in the evening, however, they recognised the low wooded isle which he had called Ushant. Several high rocks (Teste Isles) in sight when they stood off for the night served next morning as a connecting point.
On the 26th, a crowd of small islands, mostly inhabited, were seen at a short distance off, and in the background some high mountain summits were visible. Approaching more closely, D'Urville observed numerous channels intersecting the coast which they appeared to divide into a multitude of islands, and it seemed doubtful whether the land seen belonged to the Louisiade or to New Guinea. On the 27th, the two ships reached the Cul de sac de l'Orangerie--the appearance of the land at this place was considered to "agree perfectly with the pompous description" of Bougainville. D'Urville would willingly have searched for an anchorage here, but sickness prevented him from delaying much longer on this coast. Many canoes had been seen during the day, and one with six men at length came off, followed by some smaller ones, each carrying two or three people. The natives could not be induced to venture on board, and for a long time hesitated to receive some presents conveyed to them on a plank, in return for coconuts, a stone axe, and some shells. These natives appeared to be unarmed; by signs they invited the Frenchmen to visit them on shore. D'Urville was now anxious to determine whether, as represented by his charts,* a passage existed between this portion of the Louisiade of Bougainville, and what was then considered to be the south-east extremity of New Guinea, in the neighbourhood of Cape Rodney. Next day, however (28th) a high chain of mountains was seen to occupy the space assigned to the supposed passage. On the 29th, a barrier reef was found extending to the eastward in the direction of the coastline; they were unable to clearly identify Cape Rodney and Point Hood, of the English charts. In the evening D'Urville saw a chain of high mountains which he named Mount Astrolabe, and a well marked headland (Cape Passy) beyond which the coast appeared to trend to the northward. The expedition now shaped a course for Torres Strait, having in seven days made a running survey extending over a space of 450 miles in length, without anchoring or communicating with the inhabitants.**
