PURE WATER.

rliflE ROYAL FILTERS,
Sole Office 163, STRAND, LONDON, opposite the New
Church.

To purify Foul Water like that supplied to the Inhabitants of the
principal Cities and Towns in England, replete with every species
of offal and myriads of animalculaa, and to convert it forthwith
into an enlivening wholesome and chrystaline beverage like the
Mountain Spring, is one of the most difficult problems of science
which thousands in every age and country have attempted in ♦ain,
having produced at best a vapid sickening beverage, till the happy
electro-chymical invention of ROBINS'S ROYAL FILTERS
appeared. This has justly been characterized by one of the
highest practical authorities, as " The only effectual and whole-
some mode of filtration ;" as a pl•pof of the fidelity of this re-
mark, it will be sufficient to observe; that during the prevalence of
the fatal fever that has lately pervaded the Metropolis, not a public
establishment or private residence in which the Royal Filters had
been adopted was visited by the scourge ; the advantages of the
discovery has already raised up a host of humble imitators, but it
will be found that all other apparatus are imperfect in action, sub-
ject to constant disarrangement, and in many cases render the use
of the water dangerous to health. It is only necessary to add, that
the Royal Filters are protected: by her Majesty's Letters Patent ;
that they have been adopted in all the Royal Residences, the
various branches of the Public Service, her Majesty's Navy, and
the:mansions and residences of more than 180,000 families through-
out the Kingdom. To render the invention of general benefit, it
has been proposed to the Patentee by the most influential Members
of the:Colle,ge of Physicians to reduce the prices in order to render
them available to all branches of the community, and accordingly
the following scale is submitted to public attention.
