[PREFACE]

The present work is the natural product of some years devoted to a study of the speech and habits of monkeys. It has led up to the special study of the great apes. The matter contained herein is chiefly a record of the facts tabulated during recent years in that field of research.

The aim in view is to convey to the casual reader a more correct idea than now prevails concerning the physical, mental, and social habits of these apes.

The favourable conditions under which the writer has been placed, in the study of these animals in the freedom of their native jungle, have not hitherto been enjoyed by any other student of Nature.
