Object Lessons on the Human Body / A Transcript of Lessons Given in the Primary Department of School No. 49, New York City

A series of primary-level object lessons presents the human body in simple, didactic terms, naming head, trunk, limbs and their parts, and explaining basic functions of breathing, the heart, blood, arteries and veins. It gives practical hygiene rules such as keeping the mouth closed, avoiding unsafe objects, and preferring nasal breathing because it warms and cleanses air. Diet and drink are defined as sources of good blood, while alcohol and tobacco are described as poisons that impair growth, thinking, and health. The lessons also cover limb structure, joint types, cartilage, ligaments, and common injuries, using questions to reinforce learning.
