Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Virginia a very pleasant memory; to my hosts, Professor and Mrs. Scott Buchanan; to Professor Buchanan for con versations and suggestions out of which these lectures arose; and to the Revd. M. C. D’arcy, and Mr. F. V. Morley for their criticisms. It is a pleasure to me to think that these lectures were delivered at one of the older, smaller and most gracious of American educational in stitutions, one of those in which some vestiges of a tra ditional education seem to survive. Perhaps I am mistaken: but if not, I should wish that I might be able to encourage such institutions to maintain their communications with the past, because in so doing they will be maintaining their communications with any future worth communicating with.
