DAKIN'S ROYAL PATENT COFFEE.
0. introducing this extraordinary and highly important in-
vention, It will be necessary, in the first instance, to point out the
evils and imperfections arising from all other principles of roasting
and preparing Coffee at present in use.
Coffee is almost universally roasted in an Iran cylinder, which is
turned by hand or steam power over a cake fire. The Coffee is let
in and out of the cylinder by means of a slide, which is the whole
length of the cylinder, and which it is next to impossible to render
perfectly air-tight ; the consequence of this defect is, that the sul-
phurous and noxious fumes if the coke penetrate into the cylinder
and mingle with, the Coffee. We will suppose, however, the cylinder
containing the Coffee to be placed over the fire, which is then co-
vered in, cylinder and all, and the process of roasting to be commenc-
ing. The first evidence of this fact is the vegetable vapour which is
given off by the Coffee, and which vapour is more or less impregnated
with Gallic and mallic acids, which acids, acting upon the iron, form
gallates and malates with that metal. The heat continues, the va-
pour is condensed, and forms a most noxious fluid, which Is mingling
with the Coffee, and by the increasing heat is again vap.aised, and
is assisted in its destroying work by one of the most powerful acids
known, namely, by the pyroligneous acid, which is now beginning to
be given off by the Coffee most freely. This vicious acid continues
forming with the iron the acetate thereof, and imparting the same to
the Coffee, which receives, in addition, a sulphurous flavour from the
coke. It should be observed, that so astonishingly great is the quan-
tity of pyroligneous acid formed, that many ounces may be collected
from the roasting a single hundred weight of the berry. The action
of the pyroligneous acid upon either iron or copper cylinders is well
known; with the former a compound is formed which, if not de-
cidedly injurious to health, gives to the berry a most acrid and dis-
agreeable flavour; whilst, with the latter, the result is verdigris.
Again, by the usual roasting prooess, which is nothing more nor
less than a specieli of destructive distillation, what possible chance
has the aroma of this valuable berry of being properly developed?
Supposing for one moment that it were properly developed, it is well
known to be exceedingly volatile, and would quickly escape through
the crevices in the, slide of the cylinder ; whilst the vegetable vapour,
being exceedingly sluggish, and containing the vicious and noxious
acids, would remain behind, giving to the Coffee that cankerous,
acrid, and metallic taste, that renders the infusions of this otherwise
most valuable and wholesome berry a beverage avoided by the deli-
cate, and highly injurious to the health of many who consume it.
For guarding against all these evils, and for doing away with all
those long-complained-of imperfections, her Most Gracious Majesty
has been pleased to grant to Dakin and Company her Royal Letters
Patent.
The plan en which "Dakin's Royal Patent Coffee" is roasted and
prepared is as follows :—The iron cylinder is altogether done away
with, and the Coffee is never, under any circumstance, allowed to
come in contact with from. A. SILVER cylinder is substituted, and
the heat is obtained by means of the atmospheric air passed over hot
plates, by which plan, as.neither the fire, nor the fumes thereof, are
in any way allowed to be in contact with the cylinder, the evils
arising from the sulphurous vapours of the coke mixing with the
Coffee are entirely avoided The AMY Fat cylinder is so constructed
that, through apertures made for the purpose, the vegetable vapour
which contains the vicious acids from the offee, is allowed to es-
cape, whilst the apertures, being closeable at pleasure, are imme-
diately closed as soon as this, the first part of the process of roasting,
is accomplished. The SILVER cylinder then becomes air tight, and
the aroma, which otherwise would escape, is condensed on the berry,
which thereby contains all Its valued and inherent excellence. The
Coffee, after being sufficiently reacted in a SILVER cylinder, and
after being cooled down in a SILVER cooler, is ready for purchasers
who buy their Coffee whole : whilst the Coffee that is supplied
ground, is pulverised between powerful stones, and for better
preservation from the atmosphere, is recommended to purchasers
packed in glass bettle=, containing two pounds each, which are
corked down air-tight, and sealed with the Royal Arms.
DAKIN and CO. will have great pleasure in showing many testi-
monials which they have received from the most eminent physicians,
surgeons, and gentlemen of the faculty, as to the beneficial effects
and advantages of " Dakin's Royal Patent Coffee.* The following
certificate of Mr. Alfred S. Taylor and Mr. Arthur Aikin, the great
aathorities on chemistry, medical jurisprudence,:aad the sanitary
question, will, however, no doubt be deemed conclusive:—
" We hereby certify that we have chemically examined four
. .

varieties of coffee—namely, best Mocha, Jamaica, Very Fine and
Good Plantation (Ceylon) Coffee, both in the raw state and as
prepared and roasted by the patent process of Messrs. Dakin. We
have likewise chemically examined samples of the same varieties
of Coffee roasted at the same time 'in tke usual way, and the result
of this examination is that in delicacy of flavour, odour, and as an
article of diet, the Coffee prepared by Messrs. Dakin's process is, in
our judgment, superior to that prepared in the ordinary way.
"We have also examined the apparatus used by Messrs. Dakin

for roasting Coffee, and we find that all the surfaces with which
the Coffee comes in contact during this process are of silver. We
find also that great care is taken so to regulate the degree of heat
and the mode of its application as to render necessary a longer
time and lower temperature to effect the roasting, whereby all
risk of charring the berry or of producing empyreumatic oil is
preveated, the separation of acid vapour is more gradual and com-
plete, and a larger portion of aroma is retained than occurs in the
usual methods of coffee roasting.
" The process of Messrs. Dakin appears to us, therefore, in a
chemical view, better adapted than any yet suggested for procuring
roasted Coffee in a pure and wholesome form.

The canal revenue 'account showed that a net sum of
63,255/. had been received, including 7,751/. from the
last account, and 59,892/. expended in payment of in-
terest on the canal shares and loans, leaving a balance
of 3,363 L
After a short conversation, resolutions were passed,
adopting the report and approving of the arrangement
entered into for leasing the Shropshire Canal fur the

Thanks were voted to the Chairman and directors, and
the meeting separated.

BOUTH•WESTERN RAILWAY.—BRANCH TO DATCHET
—Since the opening of this line, on the 22d of last
month, the number of passengers travelling thereon have
been immense, particularly on Sundays when the wea-
ther has been fine. On the 3d and 10th of this month
more than 4,000 passed and repassed on each of those
days, 62 trains ranning in twelve hours—via., 31 down
and 31 up; to Richmond eleven both ways, going to
Datchet. On Sunday, the 17th, the number was even
greater. The inns and public-houses at Datchet could
not accommodate one- tenth of the number. It is said that
this branch is likely to prove one of the most profitable
belonging to the South-Western Company.
MARYPORT AND CARLISLE RAILWAY.—The commit-
tee of directors appointed at the late half-yearly meeting
of this company to open a negotiation with George
Hudson, Esq., M.P., met that gentleman at the Bush
Inn, on Friday last, and came to an arrangement to the
effect that they will recommend the shareholders to dis-
pose of the line, with all its liabilities, to the York,
Newcastle, and Berwick
Railway Company (of which
Mr. Hudson is chairman) at four per cent.; the arrange-
ment to take effect on the Ist of October next: with this
contingency, that whenever the York and Newcastle
Company divide nine per cent. they are to pay tie
Maryport and Carlisle shareholders five percent. It is
not likely that there will be anrcopposition to the pro-
posed transfer.—Carlisle Patriot. •
LIVERPOOL AND BURY RAILWAy.--The viaduct at
Liverpool is complete, with the exception of five arches
over the dock property. The Walton and Upholland
tunnels are finished, and all the bridges between Liver-
pool and Wigan are built. The double way is laid and
ballasted for that distance. From near Wigan to the
junction with the Bolton and Preston Railway the
bridges are all built and a portion of the permanent way
laid down, and only a few thousand yards of earth-work
have yet to be removed. The large viaducts near Bolton
are in a forward state, that at Bolton being finished with
the exception of the planking. The masonry of the
Darcy Lever viaduct is complete, and two-thirds of the
iron-work is fixed. The stone viaduct at Bury is finished.
The permanent way (double line) is laid through between
Darcy Lever and the Bury viaduct. Several of the plat-
forms and stations are built, and the signals are now
being put up; and should the weather be favourable, the
line may be opened for passenger traffic in October next.
