D&KIN'S ROYAL PATENT COFFEE.
On introducing this extraordinary and highly important in-
vention, it will be necessary, In the first instant e, to point out the
evils and imperfections arising from all other principles if roasting
and preparing Coffee at present in use.
coffee is almost universally roasted in an iron cylinder, which is
turned by hand or steam power over a coke fire. The Coffee is let
in and out of the cylinder by means of a slide, which is the whole
len:4th of the pylinder, and which it is next to impossible to render
perfectly air-tight ; the consequence of this defect is, that the sul-
phur,.us and noxious fumes if the coke penetrate into the cylinder
an I 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 orless impregnated
with gallic and mallic acids, which acids, acting upon the iron, form
gatlates 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,rised, 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 moat freely. This vicious acid continues
forming with the iron the acetate thereof, and imparting the same to
the Coffee, which receives, in addition, a sillphurous flavour from the
coke. It should be observed, that se 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 pyroligneoue acid upon either iron or copper cylinders is well
known; with the former a compound is formed which, if not de-
chiedly injurious is 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 process, which is nothing more nor
less than a species of destructive distillation, what possiblevel chance
has the aroma of this valuable berry of being properly deoped ?
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,
bei,,g exceedingly sluggish, and containing the vicious and noxious
acids, would remain behind, giving to the Coffee that canker,ms,
acrid, end metallic taste, that renders the infusions of this otherwise
most valuable and wholesome berry a beverage avoided by
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. .
he 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 iron. A SILVIER cylinder is substituted, and
the heat is obtained by means of the atmospheric air passed over hot
plates, by which plan, as neither the Are.-nor thalumes thereof,. are
in any way allowed to be in contact with the cylinder, the evi
the
ls
arising from the sulphurous vapours of the coke mixing with
Coffee are entirely avoided The SILYER cylinder is so constructed
that, through apertures made for the purpose, the vegetable vapour
which contains the vicious acids from the Coffee, 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 sufficietly roatted in a SILVER cylinder, and
after being cooled down inn a SILVER cooler, is ready for purchasers
who buy their Coffee whole whilst the Coffee tkat is supplied
ground, is pulverised between powerful stones, and for better
preservation from the atmosphere, is recommended to purchasers
packed in glass bottle-, 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
authorities on chemistry, medical jurisprudence, :and 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 the 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 se 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
" prevented, the separation of acid vapour is more gradual and coin-
" 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.

TER IL IT Y —Whatever is unproductive is with-
out intrinsic value. Mae and his Maker alike condemn that
which " yields no fruit," and we find large tracts of land abandoned
for the same reason thst caused tho barren fig tree to be cursed.
This curse clings to Sterility in every shape ; it brings upon the earth
famine. But the malediction breathes loudest and deepest into the
ear et these of the human race who remain childless ia a community
which must altogether fail, without continual additions. Not only
do such encounter the silent scorn or pity of their fellow creatures,
but their own hearts condemn them ; wealth brings no consolation
It ishe awi remarkablefeless fact that thereturn unproductivenesschildless of soilhems and
to t bosom—brings no for the .
species arises from similarity of cause. Some lands are
the produce of vitiated strata that yields an offspring as
unhealthy as itself. Others nurture in their juices the poison of
minerals, which form the foe to vegetation. Others again lose value
by being to* early worked, before they are excess cultivation, Some
soils, originally fertile, become barren by of tillage ; others
are spoiled by unwholesome manures ; and others, again, by the
want of perseverance and nerve In the husbandman. Mark the ana-
he
logy ! Man also is too often vitiated by the parent whom
springs. Man is too often ruined by the indiscriminate use of mine-
rals, such as mercury, &c. Man also tries his constitution too early,
and avertasks it too late. Man, by unwholesome contact can also in-
fect his f-ame ; and, to render the comparison complete, man can
render a naturally vital constitution unproductive through ignorance
of his organization and diffidence in his powers. Nor does the analogy
cease here. The detriments to cultivation above detailed have been
recently se entirely overcome by modern improvement in agricul-
ture, that farmers are now enabled to produce crops almost from
stone itself; and, in like meaner, Sterility in the human race is now
removable througk the profound, discoveries in physic which enlighten
the present age. In testimony of this, a volume has recently been
produced which fills the heart with hope and is calculated to remove
Sterility altogether. It is from the pen of Messrs. J. L. CURTIS
AND CO., Consulting Surgeons, 7, Frith. street, Soho-square,
London, and bears the title of " MANHOOD: The Causes of its
Premature Decline, with Flail Directions for its Perfect Re-
storation ;" and is sent by W. STRANGE, bookseller, Si,

14 O V E is the leading feeling of the human
breast. More exalted than mere passion, it soars high above
every other impulse of nature, and is not only stronger than a v arice
from
,
but more engrossing even thaw ambition. No man is exempt
its influence, er can avoid its sway ; and business, pleasure, philo-
sophy, and divinity itself become neglected under the enthralling
power of LOVE, which, unlike most things, increases in intensity
with time, until it receives the sacred consummation of marriage.
When union does not take place, however, this passion, this
fervour, this golden tide of the manliest feelings becomes a deadly
polk.n in the heart, which now darkens, as it before bright-
ened, all things upon earth. How is it that men, of most un-
changeable habits, will change at the very altar, and after a life-
time spent in the fulfilment of every engagement, snap the very con-
tract asunder which should be most binding to an honourable mind?
