CHAPTER XXIX.

MISCELLANEOUS.

Q. _Why do the BUBBLES in a CUP OF TEA range round the SIDES of the CUP?_

A. Because the cup _attracts them_.

Q. _Why do all the LITTLE BUBBLES tend towards the LARGE ones?_

A. Because the large bubbles (being the superior masses) _attract them_.

Q. _Why do the BUBBLES of a CUP OF TEA FOLLOW a TEA-SPOON?_

A. Because the tea-spoon _attracts them_.

Q. _Why are the SIDES of a pond covered with LEAVES, while the MIDDLE of the pond is quite CLEAR?_

A. Because the shore _attracts_ the leaves to itself.

Q. _Why do all fruits, &c. (when severed from the tree) FALL to the EARTH?_

A. Because the earth _attracts them_.

Q. _Why do persons (who water PLANTS) very_

_often pour the water into the SAUCER, and not OVER the PLANTS?_

A. Because the water in the saucer is _supped up_ by the mould (through the hole at the bottom of the flower-pot), and is transferred to the stem and leaves of the plant by CAPILLARY ATTRACTION, (_See p. 84_).

Q. _Why is vegetation on the MARGIN of a RIVER more LUXURIANT than in an open FIELD?_

A. Because the porous earth on the bank _sups up water_ to the roots of the plants by CAPILLARY ATTRACTION.

Q. _Why is a LUMP of SUGAR (left at the bottom of a cup) so LONG in MELTING?_

A. Because _as it melts_, it makes the tea above it _heavier_; and (so long as it remains at the bottom) is surrounded by tea fully _saturated_ with sugar; in consequence of which, the _same_ portions of liquid will hold _no more sugar in solution_.

Q. _Why does the LUMP of SUGAR MELT more QUICKLY when STIRRED ABOUT?_

A. Because _fresh portions of unsaturated tea_ keep coming in contact with the lump, and soon dissolve it.

Q. _Why does a PIECE OF SUGAR (held in a spoon at the TOP of our tea) melt very RAPIDLY?_

A. Because as the tea becomes _sweetened_, it _descends to the bottom of the cup_ by its own gravity; and _fresh_ portions of unsweetened tea are brought constantly into contact with the sugar, till the lump is entirely dissolved.

Q. _How can a SICK ROOM be kept FREE from unhealthy EFFLUVIA?_

A. Vinegar boiled with myrrh, or camphor, sprinkled in a sick room, will _entirely correct putridity_.

Q. _Why does LIME destroy the offensive smells of BINS, SEWERS, &c.?_

A. Because it combines with the _carbonic acid_ of these places, and converts it into CARBONATE OF LIME, which is entirely _free from smell_.

Q. _Why does CHLORIDE of LIME fumigate a sick room?_

A. Because the chlorine absorbs the _hydrogen of the stale air_; and by this means removes both the _offensive smell_ and the _infection_ of a sick room.

Q. _How can the TAINT of MEAT be removed?_

A. Either by washing with PYROLIGNEOUS ACID,--covering it for a few hours with common CHARCOAL,--or by putting a _few lumps of charcoal_ into the _water in which it is boiled_.

Q. _Why do these things DESTROY the TAINT of meat?_

A. Because they _combine_ with the _putrescent particles_, and neutralize their offensive taste and smell.

Q. _Why should BED-ROOMS, COTTAGES, HOSPITALS, and STABLES, be washed occasionally with LIME-WHITE?_

A. Because the lime _is very caustic_, and removes all organic matters adhering to the walls.

Q. _How can MOULDINESS be prevented?_

A. The perfume of _any essential oil_ will prevent mouldiness from ink, paste, preserves, &c.

Alum, salt of amber, borax, nitre, salt, camphor, charcoal, and pyroligneous acid, are all excellent antiseptics.

Salt, corrosive sublimates, copperas, and alum, all arrest the decay of timber. (_See p. 426._)

Q. _Why will strong SOUCHONG TEA POISON FLIES?_

A. Because it produces _prussic acid_, which destroys their _nervous system_.

Q. _Why is strong GREEN TEA UNWHOLESOME?_

A. Because it contains _prussic acid_, which destroys the _nervous system_.

Q. _Why is a DEAD man TALLER than a living man?_

A. Because at death the CARTILAGES are _relaxed_. So, also, after a night's rest, a man is _taller_ than when he went to bed.

Q. _What is SLEEP?_

A. Sleep is the _rest of the brain_ and _nervous system_.

Q. _Why can we not SEE, when we are asleep with our EYES OPEN?_

A. Because the "RET´INA of the eye" is _inactive_ and at rest.

Q. _Why can we not HEAR in sleep?_

A. Because the drum or "TYMPANUM of the ear" is placid and at rest.

Q. _Why can we not TASTE when we are asleep?_

A. Because the nerves _at the end of the tongue_ (called papillæ) are inactive and at rest.

Q. _Why can we not FEEL when we are asleep?_

A. Because the _ends of the nerves_ (called papillæ), situated in the skin, are inactive and at rest.

Q. _Why have persons in sleep no WILL of their own, but may be moved at the will of ANY one?_

A. Because the "CEREBELLUM" (or _posterior_ part of the brain) is inactive and at rest.

Q. _Why have DREAMERS no power of JUDGMENT or REASON?_

A. Because the "CEREBRUM" (or _front_ of the brain) is inactive and at rest.

Q. _Why are DREAMS such FOOLISH and INCONSISTENT things?_

A. Because the "PINEAL GLAND" is acting _without the brain_; and the _faculty of thinking_ exists in the "PINEAL GLAND," but the _faculty of judgment_ in the "CEREBRUM of the brain."

The cerebrum of the brain occupies the top and front of the skull. The PINEAL GLAND is a small conical gland (about the size of a pea) _in the brain_.

Q. _Why do some persons LOSE all POWER of SENSATION?_

A. Because the "CEREBRUM" (or _front_ of their brain) _has been injured_.

Q. _Why are many persons IDIOTS?_

A. Because the "CEREBELLUM of the brain" _has been removed_ by some accident, or _injured by some disease_.

The cerebellum is all the posterior part of the brain.

Q. _Why does a person FEEL when he is TOUCHED?_

A. The ends of certain nerves (called PAPILLÆ) situated in the skin _erect themselves_ when touched, and produce a nervous sensation called FEELING.

Q. _Why are persons able to TASTE DIFFERENT FLAVOURS?_

A. Because the "PAPILLÆ" of the tongue and palate _erect themselves_ when food touches them, and produce a nervous sensation called TASTE.

Q. _Why do very OLD people LOSE the power of VOLITION, SENSATION, and THOUGHT?_

A. Because their _brain ossifies_; and as the "_cerebrum_" (or _front_ of the brain) goes, they lose the power of _sensation and reason_; and as the "_cerebellum_" (or _posterior_ part of the brain) goes, they lose the power of _volition_.

Q. _Why are OLD people UNABLE to WALK?_

A. Because their _muscles become rigid_.

SUBLIMATES are chemical preparations, the basis of which is quicksilver. In CORROSIVE SUBLIMATES, the quicksilver is _extinguished_, either by vitriol, potter's clay, or some other ingredient.

SUBLIMATION is a similar process to distillation; only _solids_(such as metals) are employed, instead of _liquids_.

Thus the fine _blue_ used by painters is a sublimate, and made thus:--Take 2 parts of quicksilver, 3 flower of brimstone, 8 sal ammoniac; and (having ground them) put them with the quicksilver into a glass retort, luted at the bottom; place the retort in a sand-heat; and (when the moisture is given off) you will have a splendid blue sublimate for painting.
