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.
