The purpose of this work is to make the world better acquainted with the character of Livingstone. His discoveries and researches have been given to the public in his own books, but his modesty led him to say little in these of himself, and those who knew him best feel that little is known of the strength of his affections, the depth and purity of his devotion, or the intensity of his aspirations as a Christian missionary. The growth of his character and the providential shaping of his career are also matters of remarkable interest, of which not much has yet been made known. - Preface.
