564 FORMER CHARTS AND PLANS. 
was coasted, as well as the north-eastern side of Tierra del 
Fuego, by Malaspina ; and the charts of his voyage not only vie 
with any contemporaneous production for accuracy and detail, but 
are even now quite sufficient for the general purposes of naviga- 
tion. 
The Strait of Magalhaens has been explored by several navi- 
gators ; but, among the numerous plans of it extant, those of 
Sir John Narborough and Cordova are the most correct. The 
first is particularly noticed in the late Admiral Burney’s very 
useful work, and the result of the last has been published in 
the Spanish language, and is entitled « Ultimo Viage al Estrecho 
de Magallanes.” A second voyage was also made by Cordova to 
the Strait, the proceedings of which form an appendix to the 
above work. It is furnished with a good general chart of the 
coast, another of the Strait, and many plans of the anchorages 
within it. Byron, Wallis, Carteret, and Bougainville, had already 
made considerable additions to Narborough’s plan, from which a 
chart had been compiled that answered all the purposes of general 
geographical information, and might even have been sufficient for 
navigation : for the latter purpose, however, Cordova’s chart was 
much superior ; but, being published in Spain only, and its 
existence little known in England, 1 found great difficulty in pro- 
curing a copy before I sailed, for my own use. 
The southern coast of Tierra del Fuego, between Cape Good 
Success, the southern limit of Strait le Maire, and Cape Pillar 
at the western end of the Strait of Magalhaens, was very little 
known. Cook’s voyage affords several useful notices of the coast 
between Cape Deseado and Christmas Sound, and the Dutch fleet 
under Hermite partially explored the neighbourhood of Cape Horn: 
a confused chart of this coast, however, was the best that could 
be put together; and although Mr. Weddell has more recently 
published an account of the harbours and anchorages near Cape 
Horn and New Year Sound, yet little available benefit was derived 
from it, because these different navigators having confined their 
examinations to small portions of the coast, it was difficult to 
connect their respective plans, even on so small a scale as that of 
the general chart. 
The western coast of South America, which is very intricate, 
extending from Cape Victory (the north-west entrance of the
