When the heat dilates a portion of the air, this portion, lighter than the other, rises to a more elevated place and is immediate- ly replaced by another and a colder portion. What occurs daily in our apartments, is but a counterpart on a small scale of the great changes in the atmosphere without. The sea and land breezes within the tropics afford a good illustration of the effects of a comparative warmth and rarity of the air. The heat of the earth from the sun rarities the air, and the cooler and denser air from the sea flows in, causing the sea breeze—and at night the greater duration of the warmth of the sea, which from its being more deeply heated than the earth retains its heat after the earth has cooled, produces a flow of air from the land, causing the land breeze. The effects of wind upon the lungs arise from the temperature and humidity of the atmosphere manifested in transporting fogs from the sea, and from the distribution of injurious emanations, etc. Temperature.—Although the quantity of heat given off from the sun is without doubt
