NOTICE TO MARINERS.

Colonial Secretary's Office,
Auckland, 23rd July, 1858.

HIS Excellency the Governor directs the
publication of the following Prospectus
of an Invention for generating Fresh Water
from Sea Water.

E. W. STAFFORD.

NORMANDY'S PATENT MARINE
AERATED FRESH WATER COM-
PANY.-[LIMITED.]

PROSPECTUS.

This Company have become the proprietors
by purchase of Dr. Normandy's invention for
producing pure aërated fresh water from sea
water:

The invention is secured by Letters Patent
in the United Kingdom, and in France, Prussia,
Belgium, and Holland.

The Company are now applying for Patents
in Russia, Austria, and the United States.

The advantages of the apparatus constructed
upon Dr. Normandy's principles over the ma-
chines which have been heretofore in use, are:
-1. That it aërates the water, and thus makes
it pure, wholesome, and immediately fit for
drinking, whereas all other plans for producing
fresh water from salt water merely proceed on
the principle of a common still, and
the water produced by them requires
to be aërated by agitation in the tanks
or other artificial means, and even then is not
only very imperfectly aërated, in consequence of
which it remains vapid and indigestable, but is
at the same time exceedingly susceptible of
being tainted by any impurity in the atmos-
phere by which it is surrounded.-2. That it
produces double the quantity of fresh water
from the same amount of fuel.

The apparatus was brought under the notice
of his Grace the Duke of Newcastle, when
Secretary at War; and, for the purpose of
practically testing, for his Grace's satisfaction,
the working qualities of the machines, one of
them was fixed on board the North of Europe
Steam Navigation Company's ship "Levant,"
during her passage from London to the Crimea
with materials for the Balaklava Railway.

The paper marked A, in the Appendix con-
tains copies of the Reports made by the officers
and passengers on board the ship on that oc-
casion.

Lord Panmure having succeeded the Duke
of Newcastle as Secretary at War, twelve of
the machines were, under his Lordship's orders,
erected on the Island of Heligoland, for the
purpose of supplying fresh water to the Foreign
Legion stationed there. The result was en-
tirely satisfactory to Admiral Sir John Hind-
marsh, the Governor of that island, and to Lord
Panmure.

The paper marked B, in the Appendix, con-
tains copies of Testimonials and Letters to that
effect.

By order of Dr. Andrew Smith, the Di-
rector-General of the Medical Department of
the Army, and with the entire approval of
Lord Panmure, the Company has supplied one
of the machines for the use of the New
Military Hospital established at Suez.

The paper marked C, in the Appendix, will
corroborate this statement.

The Peninsular and Oriental Steam Navi-
gation Company are now erecting at Aden,
for the use of their establishment there, two of
the Company's machines capable of producing
together 5000 gallons of fresh water per diem.

The Royal Mail Steam Packet Company,
having tested the machines, by using one on
board their magnificent ship, the " Atrato," on
several voyages to St. Thomas's, have not only
decided on retaining it for permanent use on
board that ship, but are also proceeding to fit
the machines on board the other ships of their
fleet.

The paper marked D, in the Appendix, will
show that, by using the apparatus, they have
been enabled to remove a portion of their water
tanks, and thus to make room for thirty tons
more cargo, the saving thus effected paying for
the apparatus in one voyage.

The apparatus is as valuable on land as at
sea, and would be of great service at any town
on the coast deficient in a supply of water. It
might be made available for producing water
on a large scale for the use of the town, either
by its adoption by a public company, or by be-
ing used by the inhabitants on a more limited
scale for the supply of their own personal
necessities. Every house, in close proximity
with the sea, might be fitted with a small ma-
chine capable of producing the water required
for daily consumption, and, as the apparatus is
self-acting, any servant of ordinary intelligence
could attend to it.

The Prussian Government has just ordered
one of the Company's machines for erection on
a new corvette, building at Dantzig.

And not only is the apparatus essentially ap-
plicable to the production of fresh water from
sea water, as already stated, but ordinary river,
spring, well, selenitous or hard waters of every
description, and however charged with lime or
other salts, can thereby be made to yield, at an
extraordinarily cheap rate, an unlimited quantity
of absolutely pure water, and be thus rendered
available in several manufactures for which such
a liquid is an essential requisite; as, for
example, in saltpetre refining, gunpowder mak-
ing, dyeing, and for brightening colours in
calico printing.

The paper marked E, in the Appendix, is a
copy of a Testimonial from Messrs John Hall
and Son, the eminent gunpowder manufac-
turers, who have had two of the Company's
machines in operation for some time at their
works at Faversham.
