ADULTERATION OF COFFEE.

The following opinion front Dr. Ure has been ob-
tained by parties interested in the coffee trade, with a
view to its circulation among the retail dealers previously
to its coming into force. It will be recollected that it
was maintained by the late Chancellor of the Exchequer
that there was no reliable method of detecting the adul-
teration of coffee with chicory. The error of this state-
ment was demonstrated by the Lancet, but it bas been
thought advisable to take further steps to make a simple
process generally known:—
" COPE OF DR. ERE 'S OPINION ON THE POWER. OF DIS-
COVERING THE ADMIXTURE OF CHICORY WITH Cop-
FEE, FORWARDED TO CHARLES H. BURTON, 27,

MINCING-LANE.
"No problem in science is simpler or more certain
than the detection of chicory-, or of similar substances,
in coffee powder. Ground roasted coffee imparts to cold
water merely a pale sherry colour, whereas when it is

liquid in the stems of the tubes will show, by the variable
clop:hs of the tinetures,the presence and proportion of coffee
and chicory in each of them. An apparatus for making
this experiment maybe bad for one shilling, and would
give test results of sufficient precision.

THE CHINESE RAT-EATERS.—The Chinese, who
are emigrating to California on a large scale, are, it is found,
amongst the most ingenious, laborious, economical, and
docile labourers among the mines. They demand less
wages, and California is so abundantly supplied with rats,
that they can live like Celestial Emperors and pay very
little for their board. The rats of California exceed the rats
of our older states, just as nature on that side of the conti-
nentsexcels in bountifulness of mineral wealth. The Ca.
lifornian rats are incredibly large, highly flavoured, and
very abundant. The most refined Chinese in California
have no hesitation in publicly expressing their opinion of
" them rats."

ALTERATION OF MAILS FROM CHESTER.—We are
informed that the Liverpool mail, which has hitherto been
di.patched at noon, and at four o'clock r.x., will in future be
dispatched at ten o'clock A.X. and 2.40 P.M. The reason as-
signed for this alteration is that the letters dispatched at ten
A.M. will be in time at Liverpool for the mid.day delivery,
and those dispatched at 2.40 r.m. for the afternoon delivery;
but we conceive that, however advantageous such alteration
may be for Liverpool letters, some consideration should have
been had for those parties who have correspondents in the
north, and which the late noon post gave; unless the Post-
master-General will allow two more letter-carriers to effect
an early delivery, and thus enable those parties to receive
their letters in time to answer by the mail at ten o'clock.—
