what effect do they produce on those that live in them?
A. People in such habitations are rendered unhealthy and weak, paralytic and sick; they grow stupid, simple, ill-natured, and miserable: and little children grow pale in damp rooms; they swell, become consumptive, and die.
Q. How can such rooms be improved?
A. By the repeated and daily admission of fresh air into them; or, what is still better, by holes made in the two opposite walls of the house, one near the floor, through which the external air constantly passes, and expels the foul air through the hole made near the ceiling.
Q. Ought rooms and chambers to be lofty and spacious?
A. Yes; the more lofty and spacious they are, the less liable will the air be to corruption.
Q. How often should they be swept and cleaned?
A. All inhabited rooms and chambers ought to be cleaned every day.
Q. But is it good to sit in very warm rooms in winter-time?
A. No; very warm rooms are very unwholesome, and make people weak, simple, stupid, and sick.
Q. Is it wholesome to dry clothes in rooms, or boil water in ovens, where the steam cannot ascend as in a chimney?
A. No; damp vapours corrupt the air very much, and are therefore unwholesome.
Q. If one be very much chilled in winter, may he immediately approach the fire, or a hot stove?
A. No; for chilblains are produced by exposure to heat after intense cold.
