First Course in Biology

Reproduction of the original, first published in 1908. Early 20th-century secondary-school biology textbook presenting plant, animal, and human biology as a unified, practical course favoring observation, experiment, and everyday relevance over rote facts. It offers clear explanations, classroom and field exercises, and an ecological perspective tying structure and function to environment, beginning with chemistry and physics basics before surveying plant variation, selection, ecology, seeds, germination, and roots.
