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.
