_Polar Expedition._
It is known by the experience of all former voyages to the arctic
circle, that towards the end of the season, in consequence of the heat
radiating from the lard, the ice is detached from the shores of these
seas, and floats southward. Ice, therefore, does not detach from other
ice, but from the coast. Taking this principle with us, when we find
that our expedition traversed a surface of some hundred miles, we
conclude, whatever was the extent of that mass drifting south, it must
have left an equal extent of open water in its original place in the
north. We also infer, that there must be land at the north pole, from
which this body was separated; and that if it could have been entirely
crossed, Captain Parry and his companions would have found a clear sea
for the boats, and had little difficulty in reaching Polar
Land.--_Literary Gazette_.
_Pemecan._
This substance (mentioned in our recent abstract of the Polar Expedition
as part of the provision for the crew) consists of meat prepared in the
same way that the Indians prepare their provision of buffalo or deer.
The flesh, _beef_ in this case, is cut into stripes, and dried by
the smoke of wood. It is then beaten into a powder, and an equal
proportion of fat being melted, the whole is mixed up together into a
solid mass. It is evident that more of real sustenance from animal
matter cannot be combined in any less bulky or burdensome compound. It
makes an excellent and very nutritious soup.
_Egyptian Architecture._
It is somewhat surprising, that among the crowd of novelties, and
very especially of attempts to depart from the received models of
architecture, the _Egyptian_ has not taken its share. It is true
that some very partial attempts have been made; in the metropolis, we
believe, not exceeding two; and if we add to these a school recently
erected at Devonport, a mausoleum at Trentham for the Stafford family,
and an iron-manufactory now erecting in Wales, we have probably
enumerated the whole. Such as the examples have been, they have not
spread; and, indeed, we may say, that they have scarcely attracted any
notice, whether for good or evil; though the publicity and singularity
of aspect of the most accessible specimen in Piccadilly might have at
least been expected to distinguish it, in the general eye, from the
buildings by which it is surrounded. As to the public, we find no
difficulty in accounting for this. This style has not been pointed out
to them, and they have not been desired either to admire or dislike it.
Why the architects have neglected it, they must themselves explain,
since we believe there have been but two in that profession who have
been concerned with the buildings to which we have alluded, the last
named of these being an attempt of a dillettante in the art. As to the
specimens where it has been thought fit to introduce the Egyptian window
or doorway in churches of a Greek design, we consider the attempt faulty
and censurable. This is a false and misplaced ambition after novelty,
which marks far too much of what has recently been effected in our new
churches.--_Westminster Review._
_Coinage._
Coins are generally completed by one blow of the coining-press. These
presses are worked in the Royal Mint by machinery, so contrived that
they shall strike, upon an average, 60 blows in a minute; the blank
piece, previously properly prepared and annealed, being placed between
the dies by part of the same mechanism. The number of pieces which may
be struck by a single die of good steel, properly hardened and duly
tempered, not unfrequently amounts at the Mint to between 3 and 400,000.
There are eight presses at the Mint, frequently at work ten hours a day,
each press producing 3,600 pieces per hour; but making allowance for
occasional stoppages, the daily progress of each press may be reckoned
at 30,000 pieces; the eight presses, therefore, will furnish a diurnal
average of 240,000 pieces.--_Quarterly Journal._
_The Ornithorynous._
This remarkable animal, which forms the link between the bird and beast,
has a bill like a duck, and paws webbed similar to that bird, but legs
and body like those of a quadruped, covered with thick, coarse hair,
with a broad tail to steer by. It abounds in the rivers of New Holland,
and may be seen bobbing to the top every now and then, to breathe, like
a seal, then diving again in quest of its prey. It is believed to lay
eggs, as a nest with eggs in it of a peculiar appearance was some time
ago found. It bears a claw on the inside of its foot, having a tube
therein, through which it emits a poisonous fluid into the wounds which
the claw inflicts; as, when assailed, it strikes its paws together, and
fastens upon its enemy like a crab.--_Cunningham's New South
Wales._
_Sheep_
Are bred to an immense extent in New South Wales. In 1813, the number of
sheep in the colony amounted to 6,514; in 1821, to 119,777. The
exportation of wool to England during the last year exceeded a million
of pounds, and at the same rate of increase, in 1840, will reach to
between 30 and 40 millions of pounds. Bullocks are recommended for
draught in preference to horses, and the speed of a well-taught, lively,
strong bullock is little short of that of a horse.--_Ibid._
_Garden Rhubarb._
To force garden rhubarb, sow the seed on a rich moist border in the
beginning of April. Thin the young plants during the summer; in the end
of October, carefully transplant them into forcing-pots, five or six in
each pot. Place them in a northern aspect, to recover the effect of
their removal from the seed-bed, and in a month they are fit for
forcing.
_American Canals._
The canals are the most striking internal improvements in the United
States. The Great Erie canal is 360 miles in length, with an average
breadth of 40 feet. It connects the great line of lakes with the ocean
by the Hudson. Another to connect the Hudson with Lake Champlain is also
complete. Above 2,000,000_l._ have been expended on them; and the
annual returns from the tolls alone have already amounted to
120,000_l._ In the state of Ohio, another canal is in progress,
almost equal in magnitude to the Erie canal. On the rivers which it
connects with the lakes, there is a steam-boat navigation of 5,000
miles. In Pennsylvania, the Schuylkill navigation works comprise an
extent of 108 miles, of which 62 are canal, and 46 the river made
navigable. These works are complete. The Union canal, a line of 74
miles, to connect the Schuylkill with the Susqueannah, is in progress,
and will be completed within the present year. These, however, are but a
few of the gigantic strides which America is making in the march of
nations.
_Caledonian Canal._
Between August 1, 1826, and August 1, 1827, 212 vessels have passed
through the Caledonian canal from sea to sea. 295 vessels have made
partial passages through one end of the canal, to and from various
ports; 74 boats, not above 15 tons burden each, have been employed in
the carriage of articles to the fishery stations; and 91 steam-boats
have passed through the canal, all within the period abovementioned.
_Medicine._
A respectable contemporary journal gives the following calculations on
the relative state of the medical profession in London and Paris. The
French have long objected to the multitude of our professors, and the
drugs they employ; and it would seem by this comparative statement that
their objection is not ill-founded:--
In _London_ there are 174 physicians, or 1 physician to 700
inhabitants; 1,000 surgeons, or 1 surgeon to 1,200 inhabitants; 2,000
apothecaries, or 1 apothecary to 600 inhabitants.
In _Paris_ there is 1 physician to 1,300 inhabitants; 1 surgeon to
6,000 inhabitants; 1 apothecary to 4,450 inhabitants.
Being in the proportion of 1 physician in Paris to 5 in London; 5
surgeons in London to 1 in Paris; 7 apothecaries in London to 1 in
Paris.
Supposing, on an average, each of these persons to receive
1,000_l._ a year, the whole income of the medical profession in
London would be 3,474,000_l._ annually.
_Poor Rates._
About the close of the seventeenth century, the poors' rates of England
and Wales were stated, on the authority of parliamentary documents, to
amount to 665,362_l._; and the population of both to 5,475,000. In
1821, the poors' rates amounted to about 7,000,000_l._, and the
population to 12,218,000. Dividing the greater rates 7,000,000_l._
by the lesser 665,362_l._, we have about 10-1/2 to 1, which is the
proportion in which the poors' rates have increased in the last 127
years. And dividing the greater population 12,218,000 by the lesser
5,475,000, give about 2-1/2 to 1, which is the proportionate increase of
population during that space of time.
_Van Dieman's Land Wasp._
The wasp of Van Dieman's Land is a smaller but much more splendid insect
than the English wasp; it has four orange-coloured wings, and horns and
legs of the same colour, a hard body, and a formidable sting. It is an
inhabitant of the forest, and is at war with a spider that makes its
hole in the sandy places, and which is armed with a cap or door, which
it pulls over on the approach of its enemy, or in rainy weather. The
wasp hovers close over the ground, prowling from one hole to another.
Having seized its prey, it immediately kills the spider, and carries it
off to its own hole, when it is said to devour the limbs, and to deposit
its egg in the body to be hatched by the putrefaction that ensues, and
which furnishes food for the young insect produced.
