PICTURE.....-OF THE CONDITION OF THE WATER OF THE
•THAMES, AS SUPPLIED BY wiz COMPANIES TO THEIR
CUSTOMER& . That the inhabitants of the richest, largest,
most populous city in the world—the seat of a more opu-
lent body 'of _ nobility and gentry than is to be found in
any other Metropolis—should, for so long a time, have
been CoilteNted to hare SEEN DAILY RUNNING INTO THEIR.
,CISTERNS, AND TO HAVE USED, FOX ALL DOMESTIC AND
CULINARY PURPOSES, A NECESSARY OF LIFE, tin LOADED
WITH ALL SORTS OF IMPURITIES AS TO. BE PRONOUNCED,

BY PAOFESSIONAL DIEN OF THE FIRST EMINENCE, TO BE
OFFENSIVE TO THE SIGHT, disgusting to the imagination,
and destructive to the health, is a tact that would not
have been credited, and that ought not to have been
credited, but upon evidence unanswerable.
THE RESULT OP THEIR LABOURS IS THE RHOOMMEN-
DATION OF A GENERAL SYSTEM OF FILTRATION-.-A STS-

TEM, ROT. LIMITED TO VIE. FIFTY-TMELEE TDOIISAIKD

Unfortunately, at the moment when the Commissioners
were drawing up their Report, the patent for " The Royal
Filter for Cisterns" had not passed through the tedious or-
deal of office, OR IT WILL NOT BE DOt•BTICD, AFTER READ-
ING THE FOLLOWING TESTIMONIALS, THAT IT MUST HAVE
roktiEn AN IMPOETANT AND HIGHLY SATI'SFACTORY CON..
CLUSION TO THEIR LABOURS.-The subjoined extract from
aFrospeetus, issued by the Proprietor, WILL BE PERUSED
WITH THE LIVELIEST INTEREST BY ALL WHO CONSIDER

CLZANLINE4S TO BE E66PNTIAL TO HEALTH, AND THE

PURITY OF TUE ELEMENT OF NVIIICH WE ARE TREATING,
TO BR NEARLY Of EQUAL IMPORTANCE WITH THE AIR

WE BREATNE :-

" The Royal Filter for Cisterns will be found superior
to all filters hitherto invented, inasmuch as it not wily
POSSESSES THE PGIVEIL OF CLAR/FTING THE WATER. IN A

PRE-EMINENT DEGREE, BUT ALSO THAT or COIIrLETE

PURIFICATION, RENDERING THE MOST TURBID, STAGNANT,
AND PIiTID WATER, OF A CRYSTALLINE BRILLIANCY,
naciivn.ra IT 01 EVERY NOXIOUS INGREDIENT, AND, IN
PACT, PRODUCING NATURE'S NECTAR' IN THE 151(IHAST
rossIBLE PERFECTION ; THAT AS TO SAY, CLEAR ABB
DESTITUTE OE TASTE AND SMELL."
The rapidity of the proeees may be understood by a
single observation, " THAT SO FAST AS ME WATER IS
surri,l6D AT THE TOP OP THE CISTERN, SO FAST IT WILL

DISCHARGE 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 miters, had two bottles sent to him for
analysation; THE ONE TOLL OF ALL SORTS OF ANIMAL
AND VEGETABLE MATTERS IN A STATE OF DECOMPOSITION,
AND STRONGLY IMPREGNATED 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 wells,
superficial springs, or any other source, that is free from
saline and ether soluble salts, not at all injurious to
heal t h. "
In the filtered bottle he found only sixteen grains of
substances, which, on examination, proved to he 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, seine corbureted hydrogen or coal gas, and car-
bonic acid gas. Mr. Hume eencludes 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 has been adopted to filter this
specimen of water to be most effectual, and hi Jhly deserv-
ing of public encouragement." The same gentleman, at a
subsequent period, analysed two other bottles, and says,
" the opinion I hasl formed of this new process for filtering
is fully confirmed." We should add, that the water thus
analysed, ALTHOUGH ruRrOtrELY STRONGLY IMPREG-
NATED WITH GAS AN, OTHER IMPURITIES, BECAME
