Q. Is the air made cold in a similar way?
A. Yes. The air resting on the earth is made cold by contact: this cold air makes the air above it cold; and cold currents or winds shake the whole together, till all becomes of one temperature.
Q. Why is meat very subject to taint on a moon-light night?
A. In a bright moon-light night, meat radiates heat very freely; and is, therefore, soon covered with dew, which produces rapid decomposition.
Q. Why do plants grow rapidly in moon-light nights?
A. In bright moon-light nights rapid radiation is carried on, and dew is plentifully deposited on young plants, which conduces much to their growth and vigour.
Q. Why is evening dew injurious to health?
