Three parts in One: Part I: Plants; Part II: Animals; Part III: Air, Water, Heat, Light, ...Illustrated by numerous engravings. Children are busy observers of natural objects, and have many questions to ask about them. But their inquisitive observation is commonly repressed, instead of being encouraged and guided. ......

He has divided this volume into 3 parts, PLANTS, ANIMALS, and AIR, WATER, HEAT, LIGHT, etc.
