A NARRATIVE of the life of the author of the present work has been most extensively circulated in England and America. The present memoir will, therefore, simply comprise a brief sketch of the most interesting portion of Mr. Brown's history while in America, together with a short account of his subsequent cisatlantic career. The publication of his adventures as a slave, and as a fugitive from slavery in his native land, has been most valuable in sustaining a sound anti-slavery spirit in Great Britain. His honourable reception in Europe may be equally serviceable in America, as another added to the many practical protests previously entered from this side of the Atlantic, against the absolute bondage of three millions and a quarter of the human race, and the semi-slavery involved in the social and political proscription of 600,000 free coloured people in that country. William Wells Brown was born at Lexington, in the state of Kentucky, as nearly as he can tell in the autumn of 1814. In the Southern States of America, the pedigree and age of a horse or a dog are carefully preserved, but no record is kept of the birth of a slave. All that Mr. Brown knows upon the subject is traditionally, that he was born "about corn-cutting time" of that year. His mother was a slave named Elizabeth, the property of Dr. Young, a physician. His father was George Higgins, a relative of his master.
