PREFACE
Reading edition
In this little book the author recounts, first hand, a number of instances—out of many more known to him—illustrating the evolution of the mental and moral faculties in lower animals. Animal behaviour is a study which at all times gives much pleasure and amusement; but its supreme importance and interest is found in the fact that it places in our hands the master-key which unlocks the secrets regarding the Evolution of Human Morality.
