Elements of Natural Philosophy Le Roy C. Cooley

1873. The great aim of this book is to present the most elementary facts of Natural Philosophy, in such a way as to exercise the child in constantly observing phenomena and in drawing inferences from what he observes. Whenever a child is old enough to ask questions as: ""What makes the thunder?"" or ""Where does the rain come from?"" or ""Why are the clouds so pretty?"" is old enough to begin the study of natural philosophy and God.
