INTRODUCTORY NOTE
The addresses which make up this volume were
written by Professor Drummond between the years 1876 and 1881, and are now
published to meet the wishes of those who heard some of them delivered, and in
the hope that they may continue his work.
They were never prepared for publication, and
have been printed from his manuscripts with a few obvious verbal corrections. A
few paragraphs used in later publications have been retained.
Of the memorial sketches the first was originally
published in the Contemporary Review, and the second in the North
American Review.
December, 1897.
