The Author owes some apology to naval and military readers for the apparent presumption with which he has ventured to handle so many details of a professional character; nor indeed would he have undertaken the task without the able advice and correction of officers who were themselves actors in the scenes described. The valuable assistance and co-operation of Captain Hall, who was actively employed in China during the whole period of the war, and whose services in command of the Nemesis need no extraneous encomium, were indispensable to the completion of the work. The Author also gladly avails himself of this opportunity of acknowledging the kindness of Capt. Sir Thomas Herbert, R.N., K.C.B., who obligingly permitted him to have access to his plans and documents; and to numerous other naval and military officers the best thanks of Captain Hall and himself are due. Those readers who are alive to the important progress of steam navigation cannot fail to take a deep interest in the history of the first iron steamer that ever doubled the Cape of Good Hope. In the narrative of her curious and protracted voyage will be found many notices of the places she visited, and in particular of some of the Portuguese slave settlements on the east coast of Africa, at Delagoa Bay at Mozambique, &c. The description given of the Comoro Islands will probably be quite new to most readers. At the end of the work will be found an account of a visit to some of the harbours of the important island of Hainan, which must acquire greater importance through the progressive increase of our commercial intercourse with China; and in the Appendix have been added the new regulations concerning trade in China, and an abstract of the supplementary treaty recently concluded. With much diffidence, but entertaining a hope that the numerous subjects touched upon in these volumes have not been hastily or crudely handled, the Author commits his Narrative to the kind indulgence of his readers. W. D. B. OXFORD AND CAMBRIDGE CLUB, _March, 1844_. PREFACE TO THE SECOND EDITION. The rapid sale of the first edition, and the unexpected favour which the work has met with, have induced the Author to put forth a second edition, in a somewhat condensed and cheaper form. While no passages have been omitted which appeared essential to the completeness of the narrative, and none curtailed which seemed calculated to keep alive the general interest in the current of events, it is hoped, that the condensation of the whole into one volume, will be considered advantageous to a numerous class of readers.
