BEING A VERY FAMILIAR TREATISE ON ASTRONOMY.

Our opinion is, that science cannot be too familiarly dealt with; and

though too much familiarity certainly breeds contempt, we are only

following the fashion of the day, in rendering science somewhat

contemptible, by the strange liberties that publishers of _Penny

Cyclopædias_, three-halfpenny _Informations_, and twopenny _Stores of

Knowledge_, are prone to take with it.

In order to show that we intend going at high game, we shall begin with the

stars; and if we do not succeed in levelling the heavens to the very

meanest capacity--even to that of

[Illustration: AN INFANT IN ARMS--]

we shall at once give up all claims to the title of an enlightener of the

people.

Every body knows there are planets in the air, which are called the

_planetary_ system. Every one knows our globe goes upon its axis, and has

two poles, but what is the axis, and what the poles are made of--whether of

wood, or any other material--are matters which, as far as the mass are

concerned, are involved in the greatest possible obscurity.

The north pole is chiefly remarkable for no one having ever succeeded in

reaching it, though there seems to have been a regular communication to it

by post in the time of Pope, whose lines--

"Speed the soft intercourse from zone to zone.

And waft a sigh from Indus _to the pole_,"

imply, without doubt, that packages reached the pole; not, however, without

regard to the _size_ (SIGHS), which may have been limited.

The sun, every body knows, is very large, and indeed the size has been

ascertained to an inch, though we must say we should like to see the

gentleman who measured it. Astronomers declare there are spots upon it,

which may be the case, unless the _savans_ have been misled by specks of

dirt on the bottom of their telescopes. As these spots are said to

disappear from time to time, we are strongly inclined to think our idea is

the correct one. Some insist that the sun is liquid like water, but if it

were, the probability is, that from its intense heat, the whole must have

boiled away long ago, or put itself out, which is rather more feasible.

We do not think it necessary to go into the planets, for, if we did, it is

not unlikely we should be some time time before we got out again; but we

shall say a few words about our own Earth, in which our readers must, of

course, take a special interest.

It has been decided, that, viewed from the moon, our globe presents a

mottled appearance; but, as this assertion can possibly rest on no better

authority than that of the Man in the Moon, we must decline putting the

smallest faith in it.

It is calculated that a day in the moon lasts just a fortnight, and that

the night is of the same duration. If this be the case, the watchmen in the

moon must be horridly over-worked, and daily labourers must be fatigued in

proportion. When the moon is on the increase, it is seen in the crescent;

but whether Mornington-crescent or Burton-crescent, or any other crescent

in particular, has not been mentioned by either ancient or modern

astronomers. The only articles we get from the moon, are moonlight and

madness. _Lunar_ caustic is not derived from the planet alluded to.

Of the stars, one of the most brilliant is _Sirius_, or _the Dog-star_,

which it is calculated gives just one-twenty-millionth part of the light of

the sun, or about as much as that of a farthing rushlight. It would seem

that such a shabby degree of brilliancy was hardly worth having; but when

it is remembered that it takes three years to come, it really seems hardly

worth while to travel so far to so very little purpose.

The most magnificent of the starry phenomena, is the Milky Way or _Whey_;

and, indeed, the epithet seems superfluous, for all _whey_ is to a certain

extent milky. The _Band of Orion_ is familiar to all of us by name; but it

is not a musical band, as most people are inclined to think it is. Perhaps

the allusion to the _music of the spheres_ may have led to this popular

error, as well as to that which regards Orion's _band_ as one of _wind_

instruments.

We shall not go into those ingenious calculations that some astronomers

have indulged in, as to the time it would take for a cannon-ball to come

from the sun to the earth, for we really hope the earth will never be

troubled by so unwelcome a visitor. Nor shall we throw out any suggestions

as to how long a bullet would be going from the globe to the moon; for we

do not think any one would be found goose enough to take up his rifle with

the intention of trying the experiment.

Comets are, at present, though very luminous bodies, involved in

considerable obscurity. Though there is plenty of light in comets, we are

almost entirely in the dark concerning them. All we know about them is,

that they are often coming, but never come, and that, after frightening us

every now and then, by threatening destruction to our earth, they turn

sharp off, all of a sudden, and we see no more of them. Astronomers have

spied at them, learned committees have sat upon them, and old women have

been frightened out of their wits by them; but, notwithstanding all this,

the _comet_ is so utterly mysterious, that "thereby _hangs a tail_" is all

we are prepared to say respecting it.

We trust the above remarks will have thrown a light on the sun and moon,

illustrated the stars, and furnished a key to the skies in general; but

those who require further information are referred to Messrs. Adams and

Walker, whose plans of the universe, consisting of several yellow spots on

a few yards of black calico, are exactly the things to give the students of

astronomy a full development of those ideas which it has been our aim to

open out to him.
