917. Exercise and Clothing
Exercise warms, invigorates and purifies the body; clothing preserves the warmth the body generates; fire imparts warmth externally.
Therefore
, to obtain and preserve warmth, exercise and clothing are preferable to fire.
918. Ventilation
Fire consumes the Oxygen of the air, and produces noxious gases.
Therefore
, the air is less pure in the presence of candles, gas, or coal fire, than otherwise, and the deterioration should be repaired by increased ventilation.
So the Loveliest Woman may Lack Virtue.
