MAKING TEA.—Dr. Lardner, in his treatise oil
heat, remarks that vessels intended to contain a liquid at
higher temperature than the surrounding medium, and to
keep that liquid as long as possible at the higher tempers'
tore, should be constructed of materials Which are the worst
radiators of heat. The tea-urns and tea-pots are beat
adapted for their purpose when constructed of polished
metal, and worse when constructed of black porcelain. A
black porcelain tea-pot is the worst conceivable material cot
that vessel, for both its materials and colour are good radii-
tors of heat, and the liquid contained in it cools with 01
greatest possible rapidity. On the other hand, a bright metal
tea-pot is best adapted for the purpose, because it is the
worst radiator of heat, and therefore cools as slowly as poll'
Bible. A polished silver or brass tea-urn is better adapted to
retain the,heat of the water Shan. one ,pf a. dull.brown colour,
such as is commonly used. A tin kettle retaies the heat of
water boiled in it more effectually, if it be kept clean and
polished, than if it be allowed to collect the smoke and soot,
to which it is exposed from the action of the fire. When
coated with this, its surface becomes rough or black, and Is
a powerful radiator of heat.
BENEFIT OF ADVERTISINO,—Of all the facilities for
business afforded by newspapers, the advertising columns
afford the greatest. They put it in every man's power to
send his business-card into all houses and families; to make
himself ever present, to > peak for his own cause, whenever
the discussion of a subject interesting to himself comes 51P•
If he is a dry goods dealer, and in the family sewing circlet
the want of any article of clothing, or if any ornament 11
spoken of, the ready newspaper tells the story, and directs
them where they may at once supply themselves. The
stove-dealer, the coal-dealer, the milliner, tailor, shoemaker;
grocer, baker, and, in fact, every tradesman or dealer, whose
craft ministers to the comfort or necessaries of a family or
individual, finds his best and surest friends in the newspape,r.
The dullest times are precisely those when a man should so"
vertise the most. If the customer has little money to ex'
pend, he -very naturally looks about him to see where the
1 ttle can be disbursed to the most advantage. To rosin
about town and make inquiries, costs more than it comes to;
consequently, that tradesman who publishes his terms and
h's wares, is sure of ten times the amount of the sum invested.
The papers that are full of advertisements are not the best to
make an announcement in; twenty to one if your advertisr
ment is not overlooked; but those journals that contain
plenty of local news and general matter, which attract the
public mind, and whose columns are not crammed with ad'
vertisements.

MELANCHOLY SUlClDE.—Considerable excitement
was created in Wakefield yesterday, by a rumour, which
unhappily proved but too well founded, that Mr. Henri
Illingworth, of the firm of Illingworth and Hicks printers
and booksellers, had committed suicide by cutting his throat.
It appears the rash act was perpetrated in the pzivy adjoin-
ing the house, in Burton-street Deceased had been indis-
posed for some days previously, and is supposed to have per-
petrated the rash act in a tit of despondency. He was for
many years an active member of the board of streets com-
missioners, by whom his loss will be deeply felt. Some
neighbours observed that he appeared rather wild and un-
settled in aspect on Thursday, but no apprehensions were
entertained of the fatal catastrophe which so shortly ensued.

SCHOOLS FOR ST. JAMES'S, WESTMINSTER.—Tbe
governors of the poor have purchased a site of twenty acres
of land, adjoining Battersea Common, Surrey, where indus-
trial schools for boys, girls, and infants are about to be
erected under the superintendence of Mr. Charles Lee, archi-
tect. These schools are to be strictly industrial. The larger
portion of the boys will be occupied on the land, by which
means they will gain health, and be fitted for country or colo-
nial employment, instead of swelling the large pauper popu-
lation of London, the certain effect of bringing them up as
shoemakers and tailors in London workhouses.—The Builder.
SUICIDE FROM LONDON-BRIDGE.—Yesterday morn-
ing a female leapt into the water at London-bridge, and was
drowned. On the tide receding the body was discovered im-
bedded in the mud on the north shore, and removed to the
dead-house of Allhallows Barking, Seething-lane, to be owned,
and for an inquest; it is that of a female about 30, fair com-
plexion, and respectably dressed.
coroner's inquest wag held on Wednesday at
Rochdale' to inquire into the circumstances attending the
death of William Mills, a carter, aged twenty six years.
On the 4th of October the deceased and some other men
were drinking at a public-house in the town, and appeared
to have got into a squabble, half-fight, half-play, in which
Mills was borne to the floor and struck or kicked about the
back of the neck by James Ashworth, a farmer in the neigh-
bourhood of Blue Pits. The result of the kicks or blows
was complete paralysis of the lower extremities, partial
paralysis of the upper members, and an impediment to the
free action of the kidneys and other viscera. He was re-
moved to his home, and medical aid procured, but all that
the best skill could effect was unavailing, and the man died
-on Friday last. The paralysis was not however the imme-
diate cause of death, but " bed sores," the result of the long
confinement to which he was subjected. Ashworth was taken
before the magistrates immediately after the unfortunate oc-
currence at the public-house, and liberated on recognizances
to appear 'when called for to answer any charge arising out
of it; he has also been sued in the County Court for assault-
ing Mills, and was ordered to pay 301. damages, the last in-
stalment of which he paid some days ago; and he attended
with his solicitor before the coroner to answer any charge
that may there be made against him. On making a post
morteni examination of the yit was found that the para-
lysis resulted from an extravastation of blood between the
arch of the cavity from the spinal marrow and the spinal
cord itself, this pressed on the latter with considerable force.
The inquest was adjourned to the 7th of May. The point as
to the share that Ashworth had in the fatality may prove a
nice one.

It is stated that W. R. Collett, Esq., has declined
the invitation of the democratic section of the Lincoln Con-
servatives to contest the city at the next election, and that
the Protection Society have determined to give their support
to Sir E. B. Lytton, Bart , as the second Protectionist candi-
date.— StaVbt d Mercury.
COLCIIESTER.—The total population of the sixteen
parishes comprising this borough is 19,344, exhibiting an
increase of 1,554 over the census of 1841—rather a small
ratio compared with many other towns of similar size. An
excess of female population seems almost universal ; but
in this respect Colchester is somewhat remarkable in show-
ing a difference of nearly 2,000 on the side of the
ladies! The following is a summary :—Houses inhabited,
4,939; ditto uninhabited, 301 : ditto building, 14; total,
5,.154. Population, males, 8,723; females, 10,621 • total,
19,344. Total population in 1841, 17,790; increase in 1851,
1,554.

AN ELDERLY Tnro.—According to the return
given in to the officer who collected the census papers, there
a wife, and a wile's sister—whose joint ages
amount
is .
are three parties in the village of Balloch of Culloden—a
to no less a ±tgure than 1,415 years! The phe-
nomenon explained in this way—the "gudman " put
husband,
himself down at 506 (meaning fifty and six years), the
wife at 505 (tit'ty-five),. and the wife's sister at 404 (forty-
four).—Inverness courier.

The workmen employed on the Vierzon Railway,
near Riom, struck on the 11th, and left off work, demanding
to have two hours accorded them per day for their breakfast
and dinner, in place of an hour and a half. About 150 left
the line, and with their tools on their shoulders entered the
town. Not more than 30 men remain still at work. The
men who struck were, in general, labourers employed in the
cuttings.— Ga/ignuni.

As the master-tailor of the 24th Light Infantry,
stationed in the barracks de l'Etape, at Orleans, was, three
days ago, quietly dining with his wife, the floor of the apart-
ment suddenly gave way, and they were precipitated to the
cellar, together with all the furniture, &c. By extraordinary
good luck, neither the man nor his wife were injured. The
accident was caused by the sudden giving way of a rotten
boara,,Galignani,

TBE ENAMEL LED DAGUERREOTYP-E
The process of enarnellieg the Deguerreotypc,
vented by Mr. Beard, and to which we briefly al'
luded in The Sun of Thursday, is, we are satisfied,
by far the most important improvement in the art, of
photography which has been introduced since
Daguerre produced his first photograph. Up to the
.
period of the discovery and application of this enamel
by Mr. Beard, light, the creator of the photograph,
also its great destroyer ; and in the course of a feW
years, sometimes in the course of a few months, tne,
photographic image vanished altogether, decompose"
by the light and air. Various were the devices pro-
posed to fix and maintain the photograph in its
tine splendour, but all proved unsucceesful, and it
seemed as though evanescence was to be for evet
the fate of the Daguerreotype. Various varnishes.
were suggested of a similar character to those used
for oil paintings, but when applied some (If,
them decomposed the Daguerreotype, " smudging.,
it, and thus destroying it, or they cracked, gnu
thus spoiled it, as the rubbing necessary to row/
the varnish effectually rubbed out the image.
length, after a series of carefully conducted exPe:
riments, Mr. Beard succeeded in discovering this
enamel, w roc is applied to the DaguerreotyPe
under a pess of heat, and which effectual
burns in the colours and the form traced upon the piste:
in a somewhat analogous manner to that in which the
Chinese burn in the colours and figures in theft
:
finest specimens of porcelain ; and as in the finest
specimens of porcelain, so in the enamelled
daguerrotype, the figure's and colours are
indelible. 'We saw a specimen at Mr. Beard's eats'
blishment in King William-street on Thursdays
which effectually demonstrated the superiority of this
process of enamelling over every other. It was a piste'
to certain portions of which only the enamel had
;
been applied. In those portions to which the enamel
had been applied, the form and the colours were,
as perfect and as vivid as they were on the day at
was taken, whilst in every other portion of the plate
form and colour had become completely obliterated
by the action of the atmosphere. This invell.
tion gives to the Daguerreotype the permanence
and the beauty of oil or of encaustic painting.

FRENCH POLlCE.—Apartments have been engegea
during the present week for a number of the French police,
who are intended to be located in the metropolis during "'",

AUSTRIAN MINING COMPANY,--.00 Thursday 6
special general meeting of the shareholders of this comPanY
took place ar, the office in Throgmorton-street, City, to re.
ceive a report from the trustees of the company. Mr. Sa:
muel Amory took the chair. Some dispute took place aboui,
the non-admission of shareholders who had neglected to PO
their last call, which ended by their not being allowed t°
take part in the proceedings. Mr. Kennedy, ti.e secretary,
read a very voluminous report, from which it appeared that
the enormous claims of a few dissentient shareholders to be
repaid their original advances with interest, prior to the dig'
solution of the old company, which they maintained by a Pe"
tition in Chancery, had been dismissed by Vice-Chancellor
Bruce, and slice that period the same parties had been lea
to offer a compromise. The accounts showed that (the Om
expended by the company in the last twelve month!,
amounted to 8,0001., and there was a balance at the banker '
of 1,101/. 55. 11d. The report was adopted. A resolution
was passed appointing Messrs. Cunningham and Wilkinson
to represent the old company in negotiating with the SP!:
nish directors of the new company. Another resolution was
passed for allowing the trustees to take legal proceedings
against the dissentient shareholders for the expenses the
company had been put to by their litigation. After A vote
of thanks to the trustees, the meeting adjourned.
