The full presidential address recently delivered before the British Association
by Sir Arthur Keith, which has been so widely discussed, is published by Messrs. Watson in the Forum Series, under the title of Concerning Man's Origin, at the low price of is. The little book is a mine of interesting and up-to-date information by one of the greatest of our living scientists, and contains additional matter as well as the address. That this is a book to buy and study and keep is a cliché we have no hesitation in using, for it expresses exactly what we mean. Every 'clergyman, especially, should study Sir Arthur, for whatever our opinions, we cannot afford to neglect the considered judgments of one of the best minds of our day.
