An increase of one deg FT should be mode approximately per 5 deg redaction in north latitude. 1 Dotted pardon of winter comfort fine was extrapolated beyond test data. Rg. 10___ ASHAE Comfort Chart for Still Air* k Physiological Principles tirnnm air conditions for full term infants and young children up to school age. Satisfactory air conditions for these age groups are assumed to vary from 75 to 68 F with natural indoor humidities. For children (having high metabolism) at school, in winter clothes, 70 F has been considered correct, with 55 F recommended for gymnasiums. REFERENCES *C. P. Yaglou, E. C. Riley, and D. J.
