That bats are clean and not inclined to fly into your hair, are but two small facts in this fascinating little book about them. In his simple text, accompanied by his very accurate and descriptive pencil drawings on every page, Mr. Ripper tells a lot about bats-physiology, hearing mechanisms, life cycle, daily habits, and the many species from vampire to Oriental painted, and their world habitats. Too, he conveys his own interest in the balanced world of nature.
