CASES SUFFICIENT.

Thirty Fountain Pumps, that cost above 1,0001., have not cost
2/ per year for all the connectors, though twenty-four of them,
from fifteen to one hundred feet long, are used to water the
public roads from Wymandham to Aylsham, and at Yarmouth.
A Treble-acting Fountain Pump at Diss brewery (horse
power), the connectors lasted five years, lift one hundred feet.
N.B. It is the packing that scrapes up the water in the old
Pump that wears out. And it is the connector that rolls up
the water in the New Pump that wears out.
Mark the next two cases, both Pumps having done the same
work.

A Single-acting Fountain Pump at Messrs. Horton's, dyers,
Norwich (manual power). Here the connectors of the New
Pump last four times as long as did the pa-king of the old
Pump it superseded.
A Double-acting. Fountain Pump at Messrs. Stark's, dyers,
Norwich (steam power). Here also the packing of their old
Treble-acting Pump (superseded) used to last about three
mouths, now the connectors of their new pump last above six-
teen months. This noble machine has not, cost Bs. a year for
connectors, though constantly at work, and delivers eight im-
perial barrels of water per minute, PRACTICALLY PROV-
ING THAT IN SKILFUL HANDS THE NEW PRIN-
CIPLE IS DECIDEDLY THE MOST DURABLE.
The Seven Road Fountain Pumps, fixed early in 1838, be-
tween Norwich and Aylsham, have not cost a shilling, nor
varied in effect. -

The Ten Friction Pumps (alias Pumplings) mixed with
them, have often been repaired, and the other day not one of
them could answer the helm—so much for comparative frailty.

EFFECT.

At the many fair trials made by man, horse, and steam
power, the rolling principle beat the sliding principle, upon an
average, nearly eighty per cent., in raising water, 10, 20, 30,
45, and 70 feet high, and volumes of testimonials, by land and
sea, certify similar results.
But, whereas there are still many novices striving hard to
perpetuate ignorance and the Athenian spurious Pump in pre-
ference to the New English genuine Pump and common sense,
pretending that they can make miraculous fricti,n Pumps with-
out friction, . .

Therefore, let us at once come to deeds to try the ques-
tion, and shame the fool who first cries " Hold, enough."
CONDITIONS OF PROPOSED TRIALS AGAINST

TIME.

Take four Pumps of the Old Plan, and four Pumps of the

New Plan, with mechanical parts alike, and so adjusted that a
man of ordinary strength may exert his full force, and raise with-
out stopping nine imperial barrels of water five feet high, three
barrels fifteen feet, one barrel fifty feet, and nine imperial gallons
of water 200 feet high, or over the London Monument.
The number of seconds required with one pump less than
with the other, will be its gain in time and labour.
The competitors should find the pumps and the public the
pipes, in order to prove that engineers of the old school knew
as much about raising water as sucking monkeys.
Well, after all the stupid, lying, and even destructive oppo-
sition (Neatmarket to wit), the graduated scale of the Foun-
tain Pump is practically and successfully carried out from the
delivering of a single pint of water per stroke to the delivering
of 6,000 imperial gallons of water per minute.
And now to congratulate all nations upon the complete suc-
cess of an invention of boundless and undying utility, which
nature bars surpassing, is highly gratifying

P.S.—No work is worso done than that of raising water.
Respecting force and resistance both town and country
Pump-makers seem most gloriously ignorant.
I inquired of two men pumping, between London-bridge and
the Tunnel, how long it took them to fill their six-barrel water-
cart, lift thirteen feet ?—Answer : About seven minutes, quick
working. •
With a No. Six New Plan they could have done the like
work in seventy seconds.
One Fountain Pump would about equal all the three Cockney
built Friction Pumps at the Queen's Barracks, Norwich.

R. HARVEY begs leave to inform the Pub-
lic, that during his long Medical Practice, while Sur-
geon in the Hem. East India Company's Service? and-since he has
resided in Bath, he has prescribed these Pills with the most signal
success; he can, therefore, with confidence recommend them as a
most excellent Family Medicine, for removing Obstructions of the
Bowels, and keeping, by their mild operation, the whole system in
a healthy state. Dr. Harvey further begs to state, there is not a
safer, better Family Aperient Pill extant ; and that they are without
Calomel or any ether preparation of Mercury.
