SIR RODERICK I. MURCHISON’S ADDRESS. [May 24, 1858. 
western, as well as on tlie eastern, shore of the gulf. A table of 
maritime positions, just printed at the Admiralty, and embodied in 
the latest edition of the chart of the gulf, will enable all map 
makers to correct the hitherto almost unknown outline of the coasts 
of that kingdom. 
In Australia , a survey of Port Jackson has been made by the 
officers of H.M.S. Herald , and is in course of publication at the 
Admiralty ; some additions also have been made to the approaches 
to Princess Poyal Harbour. Here, and on Breaksea Island, lights 
have just been established as a guide to the anchorage for the 
Australian mail steamers, which at present all call at this port on 
their homeward voyage. 
New Zealand. — Detailed coast charts of the entire circuit of this 
group of islands, the fruit of ten years’ labour of Captains Stokes and 
Drury, with their zealous staff of assistants, on an uniform scale of 
5 miles of longitude to an inch, or on an average scale of one mile 
to a quarter of an inch, 13 in number, are now engraved, as are 
also a complete series of the numerous ports and havens dotting the 
extensive sea-hord. 
Those singular arms of the sea, forming a network of harbours on 
the south shore of Cook Strait, one of them Queen Charlotte Sound, 
famous as the chief place of resort of the circumnavigator Cook, are 
being engraved on a scale commensurate with their nautical import- 
ance, and on their completion, by the close of the present year, it 
may he considered that the hydrographic features of Hew Zealand 
are fully delineated. 
In Vancouver Island and in the Straits of Juan de Fuca, Eosario, 
and the Haro Channel, a survey is in progress under Captain 
Eichards, of H.M.S. Plumper , ably seconded by his staff of assist- 
ants, Messrs. Mayne, Bull, Pender, and Bedwell ; the Bay of Se- 
miahmu has been examined, and the site of the recently discovered 
gold mines fixed at some 50 miles up the river Frazer. On the 
Oregon coast two charts, for which we are indebted to the U.S. 
Coast Survey of this region, from Diego Bay to Vancouver Island, 
have been published at the Admiralty ; and in the Gulf of Califor- 
nia, Captain Flarvey, in H. M. S. Havannah , zealously assisted 
by Mr. Hull, Master r.n., has rectified the positions of various 
points of that little known coast, which have been inserted in the 
charts. 
In the River Plate Lieut. Sidney, r.n., has completed a plan of 
Buenos Ayres and its roadstead, which has been published; while
