The work contains sailing directions, extracted from English surveyors and navigators. Where the extract has been sufficiently long to make it at all desirable, the Editor, instead of re-translating them from the French, has taken them from the English originals; this has been the case with Hood, Hunter, Blackwood Earle, King, mckenzie, Weddell, and Vancouver. The directions for the outer route from Sidney to Torres Strait have been taken from the Australia Directory, published by the Admiralty, Vol. II., 1859; the' selec tions vary but slightly from those of Captain Kerhallet.
