PREFACE TO THE THIRD EDITION
I much regret that the demand for a new edition of this book should come at a time when circumstances prevent me from undertaking such a revision of the work as I feel to be required. Since the appearance of the Second Edition many important facts bearing upon the subject have been brought to light, new theories have been advanced, and old theories, supported by fresh arguments, have been revived. To all this, however, I can do no justice, as I am at present being engaged in anthropological research in Morocco. This edition is, in consequence, a mere reprint of the second. But I purpose, after my return to Europe, to issue an Appendix, in which the book will be brought more up to date and some criticism will be replied to.
