Unfortunately, at the moinent when the Corittnissioners
were drawing by their Report, the patent for " The Royal
iltear for Cisterns" had MA passed through the tedious or-
deal of office, Ok IT WILL NOT BE DOUBTED, AFTER READ-
IN4 THE FOLLOWING TESTIMONIALS, THAT IT MUST HAVE
FORMED AN IMPORTANT AND HIGHLY SATISFACTORY CON-
CLUSION TO THEIR LABOU Es.—The subjoined erraet

I WE ERTIATHE:—

" The Royal Filter for Cisterns will he found superior
to all filters hitherto invented, inasmuch as it not only
POSSESSES THE POWER OF CLARIFYING TUE WATER IN A
PRE-EMINENT DEGREE, BUT ALSO THAT Or COMPLETE
PURIFICATION, RENDERING THE IkrOST TURBID, STAGNANT,
AND FOETID WATER, OF A CRYSTALLINE BK/LLIANCY,
DEPRIVING IT OP EVERY NOXIOUS INGREDIENT, AND, IN
FACT, PRODUCING NATURE'S NECTAR' IN THE HIGHEST
!POSSIBLE I'ERFF.CTION ; THAT IS TO SAY, CLEAR AND
DESTITUTE OF TASTE AND S►LELL."

The rapidity of, the process may be understood by a
single observation, " TVAT SO FAST AS THE WATER. IS
SiPPLIED AT THE TOP OF THE clarrtnx, SO FAST IT WILL
DISCHA RG E. ITSELF FROM-THE. BOTTOM."

" But where," the reader will naturally exclaim, " is-
the proof of all this to be found? We must have some-
thing more solid and satisfactory than bare assertions."—
The following statement must, we think, set the doubts of
the most sceptical at rest for ever.
Mr. Hume, the respectable and talented chemist of Long
Acre, who has long been employed by Government in
analysing waters, had two bottles sent to him for
analysation; THE ONE FULL OF ALL SORTS OF :ANIMAL
AND VEGETABLE MATTERS IN A STATE OF DECOMPOSITION,
AND STRONGLY IMPREGN4TED WITH GAS; the other, a
bottle which had contained the same foul ingredients, but
had been purified by the Royal Filter.
In the unfiltered bottle he found, he says, forty-six
grains and a half of solid matter, of which thirty grains
consisted of impurities, and the remaining sixteen grains
were the original ingredients peculiar to the water, and
dissolved in it : " for," he observes, " there is no water,
however pure and wholesome, whether from deep well.,
superficial springs, or any othet source, that is free from
saline and other soluble salts, not at all injurious to
health."

In the filtered bottle he found only sixteen grains of
substances, which, on examination, proved to be the same
materials peculiar to, and soluble in, the water in its pri-
mitive state, and perfectly free from the impurities and
contingent foulness of the water, occasioned principally by
decayed vegetable matters, a slight impregnation by animal
substances, some carbureted hydrogen or coal gas, and car-
bonic acid gas. Mr. Hume concludes with bearing the
following high testimony to the merits of this discovery:
" After a very careful analysis, I cannot hesitate to pro-
nounce the method which bas been adopted to filter this
specimen of water to be most effectual, and highly deserv-
ing of public encouragement." The same gentleman, at a
subsequent period, analysed two other bottles, and says,
" the opinion I bad formed of this new process for filtering
is fully confirmed." We should add, that the water thus
analysed, ALTHOUGH PURPOSELY STRONGLY IMPREG-
NATED WITH OAS AND OTHER. PMFORITIES, BECAME

CRYSTALLISED, AND DESTITUTE OF TASTE AND SMELL.

Thus it is clearly proved, TIIAT OP TOE FORTY-SIX
GRAINS AND A RALF OF SOLID MATTER ORIGINALLY
PLACED IN TDB ROYAL FILTER, ONLY SIXTEEN GRAINS
OF SUBSTANCES PASSED THROUGH. IT; AND WHICH SIX-
TEEN GRAINS ARE PROYRD TO BE PECULIAR TO WATER

IN ITS PRIMITIVE STATE, AND NOT AT ALL DELETERIOUS
TO HEALTH. However much, therefore, the observation of
the Commissioners may apply to all former systems of
filtration, it is greatly to be regretted that, before the close
of their labours, they had not the benefit of the preceding
experiments, and of the following striking testimonials
to the excellence of " The Royal Filter."
Professor Brande, Dr. Clarke, Mr. Brodie, Mr. Keate,
Dr. Scutlamore, and 30 other highly eminent and unpre-
judiced medical men, have each had the Royal Filter
placed in their cisterns, and they all concur in stating
that it renders the most turbid, foetid water of chrystaline
brilliancy, and free from taste and smell.

It should be observed that the difficulty of getting
pure water is very common in most of the large towns,
-end indeed throughout the provinces. The difficulty or
necessity of placing a Filter at this distance is now rcmoved.
Portable ones of all dimensions, capable of filtering from
50 to 500 gallons every 24. hours, have been adapted to
present .the inconvenience alluded to. The expence is from
30s. to 41. er 51.

We trust we have said enough to draw general attention
to the merits of a discovery so highly iranducive to Vie
cleanliness, comfort, and health of the inhabitants of this
thickly peopled Metropolis. We shall only add that the
apparatus 'nay be inspected at the Offiee of the Patentee,
Mr. George Robins, 69, Strand, opposite the Adelphi
Theatre ; where the public are invited to have ocular de-
monstration of the efficacy of this remedy.
