In the filtered IN-Atio 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 inipnrit.ies and
contingent foulness of the water, netasioned principally by
decayed vegetali7e te.att,:,.r.) a slight impregnation by animal
substances, sem:, tathureted hydrogen or coal gas, end ear-
bouiit e:itt gas. Mr. Hume concludes with hearing 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 efii:etual, and highly descry- 1
ing of public encouragement." The same gentleman, at a
subsequent period, analysed two other bottles, and says,
" the opinion I had formei of this new process for fiitering
is fully confirmed." We should add, that the water thus
analysed, A I.THOUGH ror.rosaLv STRONGLY IMPREG-
NATED WITH GAS ANA OTHER 1311YERIT1ES, BECAME
CRYSTALLISED, AND DESTITUTE OF TASTE AND SMELL.
TIM'S It is clearly proved, THAT OF THE FORTY-SIX
GRAINS AND A HALF OF SOLID MATTER ORIGINALLY
PLACED IN TIEE ROYAL FILTER, ONLY SIXTEEN GRAIN./
OF SUB.TANCRIE FAStiED THROUGH IT ; AND NV/110E( SIX-
TEEN GRAINS ARE PROVED TO BE PECULIAR. TO WATER
IN ITS FRIMITIVE STATE, AND NOT AT ALE DELETERIOUS
To HEALTH. However much, therefore, the observation of
the Commissioners may apply to all former systems of
filtration, it is greatly to he 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. Keute,
Dr. Seudainore, 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, fietid water of ehrystaline
brilliancy, and free from taste and smell.

It should be observed that the difficulty of getting
pure wt.ter is very coalition in most of the large towns,
and indeed throughout the ptavinees. The difficulty or
necessity of placing a Filter at this distance is nowremoved.
Portable ones of all dimensions, capable of filtering- from
50 to 500 gallons every 24 hours, have been adapted to
prevent the inconvenieuce alluded to. The expence is from
.Nos. to 41. or 3/.

We trust we have eaid enough to draw general attention
to the merits of a discovery o highly conducive to the
cleanliness, comfort, and health of the inhabitants of this
thickly peopled Metropolis. We shall only add that the
apparatus osay be inapected at the Office of the Patontee,
Mr. George Robins, 69, Strand, opposite the Adelphi
Theatre ; where the public ore invited to have ocular de.
tnonstration of the efficacy of this remedy.
