The author compiles and analyzes returns from numerous colonial schools and training institutions to document attendance, age distribution, and mortality patterns. Results show higher death rates than those of comparable children at home, with infectious childhood epidemics dominating in some regions while tubercular disease is prominent in particular institutions. The analysis connects elevated mortality to poor building construction, inadequate ventilation, unsanitary surroundings, long instructional periods, and scarce play or physical education. It also highlights inconsistent, incomplete record-keeping and concludes that the available statistical material is insufficient to yield fully reliable practical guidance.
