of heat is caught in the act of running away,
and made to do useful work in some way or
other. Here is another range of formidable
dimensions, which claims credit for its
Stourbridge fire-clay back, its frontage susceptible
of variation in size, and its bars hung on
hinges to facilitate cleansing. Here is another,
adapted to the wants of boys or girls in a
boarding school; it has a formidable array of
sixteen spits, on which sixteen joints of meat
may be impaled at once; and the bars,
instead of being solid rods, are hollow tubes
filled with water, as a means of economising
heat. Here is a range in which the inventor
has sought to indulge the Englishman in
what he so much loves, an open cheerful fire,
and at the same time to have the means of
speedily converting it into a closed fire to
economise fuel. Then we have stoves in
which fire lumps are used; that is, slabs or
bricks of Stourbridge clay are built into the
sides and back of the stove, for the sake of
the great power which this substance
possesses of retaining heat. Then we have the
American Improved Excelsior, a sumptuous
name for an air-tight double oven cookery
stove; in which the hot air, instead of being
allowed to roam about hither and thither,
is brought to work in a definite way at a
definite spot. Every imaginable mode is
adopted, in these various ranges, and grates,
and stoves, and ovens, to effect this heat-
economy; if the heat is not required to act
directly upon the food, it is made to heat a
vessel of water, or a cavity which may serve
as a baking oven, or a plate of iron which
may be useful as a hot plate for dishes. Only
save the heat, and you may be certain of finding
it a useful servant in some way or other.

Commend us forthwith to this ingenious
roasting-jack, called the Automaton. See
how, in front of the range, is placed a sort
of hemispherical oven; how a hollow tube
projects from the lower part of this oven;
how this tube thrusts itself into an opening
beneath the fireplace of the range; how, by
the heat in the interior of the oven, a current
of air is sucked through the tube; how this
current sets in rotation a van wheel; and
how this wheel twirls round the hooks to
which the joint of meat is suspended. Let
not material philosophers think that they
alone understand the production of a current
of wind by rarefaction due to the action of
heat; here we have it all, in this roasting-
jack. And see, in another instance, how Mr.
Remington brings the theory of reflected
heat to throw dignity upon his roasting-
jack. Look at the concave metallic reflectors
above and below, reflecting the otherwise
wasted heat upon the savoury joint; look at
the cunning little hole in the middle of the
lower reflector, to let the rich essence drop
from the meat into a little cup below; and
look at the similar hole in the upper reflector
through which the essence may be poured
down to baste the meat They use a concave
metallic speculum, with a hole in the middle
for the reflecting telescopes; and so they do
for these roasting-jacks; therefore, &c. &c.

The bachelor's kettle is a crafty means for
inducing a man to remain a bachelor, by
making his life as easy as a glove. See what
he can obtain for three shillings. He asks
his landlady, or Polly the housemaid, to
purchase one penny-worth of patent firewood;
which firewood consists of a sort of wheel or
a sort of gridiron mysteriously formed of
small pieces of wood, resined to make them
more captious and peppery. One of these
structures he places in a little stove or grate;
he kindles it; he places the stove on the hob
to give the smoke and the chimney a chance
of becoming acquainted; he surmounts the
pile by a flat tea-kettle containing water; and
by the time the farthing wheel or gridiron
has burnt itself out, there is boiling water
enough to make moderate coffee for a
moderate man. And if he will consume two patent
firewoods instead of one, and has a little flat
pan adapted to his apparatus, he can manage
to dish up a steak or chop while the coffee
is brewing. Bachelorship apart; there is
really something in this power of making a
cup of coffee for one's self, say before starting
by the six o'clock train on a winter's
morning, and before fires are lighted or housewives
stirring.

A coffee-pot is not a coffee-pot now: it is a
mechanical pneumatico-hydrostatic piece of
apparatus. Let us not for one instant imagine
that making a pot of coffee is a trifling affair,
beneath the dignity of scientific cookery. Ask
the inventor to explain the action of his coffee-
pot. "Sir," (he will thus discourse) "there
are here different vessels or receptacles, which
come successively into use. This glass vase,
at the top, is furnished with a long narrow
tube descending nearly to the bottom of this
metallic urn. We put boiling water into the
vase; it descends through the tube into the
urn. We put the ground coffee upon a small
perforated silver plate within the urn. We
apply a spirit lamp beneath, and—"  "Oh,
I see; the water boils up through the tube
to the coffee." "Pardon me, Sir, it does not
boil up; it is driven up. Steam, formed on
the surface of the boiling water in the urn,
forces by its elasticity the water up the tube
into the glass vase, where it acts properly
upon the ground coffee. We then remove the
lamp; the formation of steam ceases; a
partial vacuum is formed in the urn; and
the external air, pressing on the liquid in the
open vase, forces it first through the coffee-
grounds, and then through the perforated
silver-plate, into the urn below." "Oh,
indeed!" "Yes, in a cheaper apparatus we
boil on an open fire; but the urn with the
spirit-lamp is a much better contrivance.
The apparatus is elegant in design, it is very
simple in use, it is free from disagreeable
odour, it enables you to make your coffee
on your breakfast table, it boils the coffee
