With beautiful full-page Illustrations. Cloth Gilt, 5s. "The volume is prettily got up, and the views of Arctic scenery are about the best we have seen in any recent work of the kind."--_Athenæum._ "Thanks to English pluck and perseverance, combined, in so many instances, with the ability to write a book, we have become as familiar with Arctic-life scenes and adventures as they can be made so by description. In the present well-got-up little volume, we have an account of the first voyage of the _Pandora_.... We can heartily recommend Lieut. Innis-Lillingston's narrative--his first attempt, as he tells us, at book-writing--as giving a graphic account, in a very unpretentious style, of his most interesting, but perilous cruise.... As a gilt book, we can also recommend the _Land of the White Bear_, for it is exceedingly well illustrated, and both in letter-press and binding is in the Messrs. Griffin's usually good style."--_U.S. Gazette._ THE LAST FOUR DAYS OF THE "EURYDICE." By Captain E. H. VERNEY, R.N. With Portrait of the "Eurydice." Cloth. 2s. 6d. "Capt. Verney has done his work remarkably well, and with the best possible taste.
