A. Thus:--the air which cases the body _absorbs as much heat from it as it can, while it remains in contact_; it is then blown away, and makes room for a _fresh coat of air_, which does the _same_. Q. _Does the AIR (which encases a naked body) become by contact as WARM as the BODY itself?_ A. It would do so, if it remained _motionless_; but as it remains only _a very short time_, it absorbs as much heat as it _can in the time_, and passes on. Q. _Why do we feel COLDER in WINDY WEATHER, than in a CALM day?_ A. Because (in windy weather) the particles of air _pass over us more rapidly_; and every _fresh_ particle takes from us _some_ portion of heat. Q. _Show the wisdom of God in making the AIR a BAD CONDUCTOR._ A. If air were a _good conductor_ (like iron and stone) the heat would be drawn _so rapidly from our body_, that we must be _chilled to death_. Similar evils would be felt also by all the animal and vegetable world. Q. _Does not the bad conducting power of air enable persons to judge whether an EGG be NEW or STALE?_ A. Yes; touch your tongue against the shell at the larger end; if it _feels warm_ to the tongue, the _egg is stale_; if _not_, it is new-laid. Q. _Why will the SHELL of a STALE EGG feel WARM to the tongue?_ A. Between the shell and the "white of the egg" _there is a small quantity of air_, which _expands in a stale egg_, from the _shrinking of the white_. Q. _Why does the expansion of air (at the end of an egg) make it feel WARM to the tongue?_ A. As air is a very bad conductor, the _more air an egg contains_, the _less heat will be drawn from the tongue_ when it touches the shell. Q. _Why do ladies FAN themselves in summer, to make their FACES COOL?_ A. The fan _puts the air in motion_, and makes it pass more _rapidly over their face_; and (as the temperature of the _air is always lower_ than that of the human _face_) each puff of air _carries off some portion of heat_ from the face. Q. _Does FANNING the air make the AIR itself COOLER?_ A. No; fanning makes the _air hotter and hotter_. Q. _Why does FANNING the air increase its HEAT?_ A. By causing the air continually to _absorb heat from the human body_ which it passes over. Q. _If fanning makes the AIR HOTTER, how can it make a PERSON feel COOLER?_ A. Fanning makes the _air hotter_, but the _face cooler_; because it keeps _taking the heat out of the face_, and _giving it to the air_. Q. _Why is BROTH COOLED by BLOWING it?_ A. The breath causes a rapid _change of air_ to pass over the broth; and (as the air is not so hot as the broth) _it keeps absorbing heat_, and thus makes the broth cooler and cooler. Q. _Would not the air absorb heat from the broth just as well WITHOUT BLOWING?_ A. No; _air is a very bad conductor_; unless, therefore, _the change be rapid_, the air nearest the surface of the broth _would soon become as hot as the broth itself_. Q. _But would not the hot air PART with its heat instantly to the CIRCUMJACENT air?_
