This unpretentious book does a pretty successful job of putting into simple, clear language the complex functioning of life, both vegetable and animal. It answers many questions for curious children: What makes you breathe? what are bones? what are germs? and so on. Too bad it skirts the most urgent questions in children's minds -- the only mention of reproductive processes is the old ""bees and flowers"" -- which doesn't answer the real questions. Too bad, also, that the book is so unattractive in format and illustrations. It has all the ear marks of the old fashioned school reader.
