PREFACE.

The Addresses, Lectures, and Essays gathered together in this volume have appeared at intervals during the past seven years, and I can give no better reason for republishing them in their present form, than the fact that three earlier collections of a similar nature have been received with favour, and, indeed, have not yet ceased to be in request.

I beg leave to offer my best thanks to the Editors and Publishers of the various publications in which these pieces have appeared, for their kindly accorded permission to reprint them.

London. October 1881.
