only to stimulate this Missionary movement, just now the great question of our Church, but also to help forward in some degree the regeneration of Africa.

In that introduction the reader is reminded of the interest belonging to Dr Livingstone's work, aims, and reception both at Oxford and Cambridge, as well as of several other matters of moment.

Professor Sedgwick's Prefatory letter must be called a valuable contribution to our literature. His object in writing it was three-fold, involving weighty considerations. He was not only desirous of bringing out into bold relief the true character of the natives of Central Africa, but he was doubly anxious to record his abhorrence of African slavery. This he has boldly done. With characteristic ability he touchingly exhibits the wickedness of this curse of Africa, together with its cure on the one hand; whilst, with nice discrimination on the other, he points out the leading traits of Livingstone's character, as those of a Christian hero, seen transparently by the light of his own works1. Such a contribution from such a pen, hearty, honest, conclusive as it is,-will live long after its writer has been numbered among our Cambridge mighty dead, the protest of the friend of Clarkson and Wilberforce against the negro's wrongs, and the witness of the noble sentiments of him who was foremost among us all in according to Dr Livingstone that warm and distinguished reception, which was so much his due.

1 Prefatory Letter, pp. 218-223.

I am aware that this volume has a somewhat incongruous appearance when examined according to the strict rules of book-making. I ask the critics to spare me on this head. In explanation I take leave to say that unavoidable circumstances have produced this irregularity, and not the want of power or of a better plan, on my part, for the arrangement of its pages.

My design in putting forth this publication was to call general attention to the greatness and vast results of Livingstone's work; as well as to the weight and number of the negro's needs. This was not all. My main object was that of striving to stir up public sympathy and Christian activity in the cause of Africa. One seemed to see this sight, to hear this plaint, only; on the one hand, the negro's gesture and cry of agony for redress going up continually before the throne of God;-and, on the other, Livingstone witnessing that unutterable woe-listening to that passionate appeal: and, with his soul so deeply stirred within him, coming home to tell his countrymen of their complicity in deepening that woe, and of their ability and duty to try and alleviate its pangs.

We have heard his story, pondered its detail and acted on its suggestions; herein are recorded some of its fruits, reminding Christian England of her duty not to neglect his charge-deliberately left with our Church and Universities to keep open those regions of Central Africa which he has unlocked; and to give to the inhabitants thereof the blessings of Evangelization and civilization.

Dr Livingstone has indeed LEFT A TRACK behind him! not only in this seat of learning but also in those of Oxford and Dublin. He has sown seeds in soils wherein have been cultivated for centuries bright genius, deep research, high resolves and great deeds, which will in the end produce marvellous and enduring fruits in Africa.

The confidence expressed in the introduction to the first Edition, with regard to the energy and large-hearted piety of the members of the University of Oxford, ought to have been stated more precisely than in such a passing notice. The passage stands thus;.' We may conclude that a corresponding good effect was produced by his visit to Oxford, where he pronounced like burning words with equal power and grace1.'

At the time of writing that introduction neither had I nor any one else here conferred with our Oxford friends with regard to Livingstone's visit and lectures there. Now that deputations (of which I was a member) sent from Cambridge on behalf of THE OXFORD, CAMBRIDGE, AND DUBLIN MISSION TO CENTRAL AFRICA,' have been honoured by so generous and distinguished a reception among that learned body on two occasions, I can reiterate from the testimony of many witnesses how great an impression was likewise produced in Oxford by Dr Livingstone's visit. What was wanted there was a record of that visit similar to this, in order to keep that interest alive and thereby to ensure lasting results.

It was with great pleasure that I learned from many persons who were present at the Livingstone gathering in the Sheldonian Theatre, that the two Cambridge lectures herein republished are mainly a reproduction of the Oxford address; precisely so in matter, and frequently so in expression.

: Hence in one point of view, especially when the mission is taken into consideration, the title of the book might have been changed with some propriety into that of DR LIVINGSTONE'S OXFORD AND CAMBRIDGE LECTURES.' In this sense I ask our Oxford friends to adopt this work, since it presents a portrait of their Livingstone meeting, as well as echoes their own sentiments and feelings, with regard to Africa and the work of Christian Missions.

It will be seen by referring to the introduction beforementioned1 that I proposed therein to devote the proceeds of the sales to the purchase of books for two libraries, and for Sichuana Bibles for Central Africa. I am sorry to say that a considerable loss instead of gain, on that edition, prevents me from carrying out so desirable an object. Dr Livingstone took the books with him to Africa which were presented to me for him, and if any person is desirous of increasing that library I shall be pleased to take charge of any books presented for the purpose.

With no small amount of care and labour I have collected from various sources the new information which 1pp. 4-8.

we have received from time to time since the publication of this book respecting the proceedings of the Zambesi expedition; as well as some statements of great importance with regard to other similar expeditions and the general well being of Africa1.

I thought it highly desirable also to state briefly the origin and history of the Oxford, Cambridge, and Dublin Mission to Central Africa; as well as the principles on which it is based. This is done in order that this volume may be more completely a hand-book to the mission, and in acknowledgement of the kindness of the committees in recommending its perusal to the friends of the mission. Finding also that this work has generally been made such a hand-book for the preparation of speeches, lectures, &c., on the Central African question, I have hence been encouraged to make it a more complete manual than ever it was for so desirable a purpose.

I have printed at the end of this book the extracts from Dr Livingstone's letters, which have from time to time appeared since he left the country. This is a valuable contribution, since there is so much freshness, vigor, and information in his correspondence3.

Several improvements on the former volume have herein been made. Running titles and continuous paging have been adopted: what few typographical or other errors existed have been corrected; as well as occasional emendations in diction made.
