THE UNDULATING RAILROAD.

I challenge any scientific man to DISPROVE, by mathe-
matical reasoning, or by expel iment, that a carriage of any
given weight, and propelled or dragged by any given power,
will traverse a curve of any given dimensions, whose two
summits are of like altitude, i❑ less time than the Sallie
carriage, propelled or dragged by the same power, will
traverse a hoe izontal line of a length proportionate to the
direct distance between the two highest points of the said
curve; provided always that the average angle of inclina-
tion, either of the ascending or descending lines of the
curve, shall not exceed an angle of 45 degrees, nor the en•
tire length of the curve be too limited to admit of the free
passage of the carriage, the surface of the horizontal plane,
and of the curved line, being precisely alike.
And I moreover challenge any scientific man to DlS-
raovE, either by m ithematical reasoning, or by experi-
ment, that a carriage propelled or dragged by locomotive
power, will traverse the whole extent of such before-men-
tioned curve with facility, and with a load which that
same power could nut move on a horizontal plane of the
'die surface. RICHARD BADNALL ,

We request our reader's attention to the fol-
lowing. The monster—the miscreant, Nero NICHOLAS

is, it seems, at work again :
Several letters from the frontiers of Poland announce that
the young lady Haweeker, aged 18, was recently shot at Lubin
by the Russians, accused of having furnished to the insurgents
provisions; she proceeded quietly to the place of execution be
tween a file of Russian soldiers. Count Michel Wollowicz having
returned from France put himself at the head of the insurgents in
the environs of Grodno ; having engaged in a skirmish with the
Russians, he was wounded and taken prisoner, and was imme-
diately hung at Grodno. Although this execution took place,
and numerous arrests, the insurgents are augmenting in force
in the whole of Volhynia and Podolia, and it is stated that the
ltussians have been obliged to retreat from all the villages.
The citadel of Warsaw will soon be !Wished ; and Kiew is also
to be strongly fortified.

THE FUNDS.--(THIS DAY.)

CITY, TWELVE O'CLOCK.
By the French mail this morning we have the following :
__.

From Vienna they state that the Emperor will now depart
for the waters of Baden, and, in the month of August he will
proceed to Brunn, where an imperial camp will be formed.
The Emperor has renounced the project of going to Prague, in
consequence of which it is probable that Charles X. will remain
a long time with his family at Ibradochin. The Countess of
St. Aulaire has paid a visit to the Emperor and Empress, and
was well received. It is hoped that the next courier from
Constantinople will bring us the information of the departure
of the Russians, both by sea and land, from Constantinople.
This event will prove the disinterested views of the Emperor of
Russia, and that a complete understanding prevails with Aus-
tria and Prussia.

The following is an account of the five comps for reviews,
going to be formed :

" That of St. Omer will be under the command of Generals
Teburce and Sebastiani for the infantry, and Gen. Dejean will
command the cavalry. That of Wattingnies, near Maubeuge,
will be under the direction of General Achard for the infantry,
and General Larristone for the cavalry; that of Rocroy will
be under the command of Generals Jamin for the infantry,
and St. Geniez for the cavalry; that of Luneville, where there
will be 24 squadrons of cavalry, without infantry, will be under
the command of General Jacqueminot. At Compiegne there
will be 6 battalions of infantry, and 12 squadrons of cavalry,
under the command of the Duke of Orleans. The infantry
are to unite at their several places of destination on the 15th
of July, and the cavalry on the 15th of August. The camps will
last for three months.

An illustrious officer of the engineers was consulted, it is
said, by the King respecting the fortifications to be made round
Paris, to which he answered, " All this is ♦ery fine and good,
but we shall not be able to execute our plans ; the population
of Paris will not have it," which has been confirmed.

Accounts from Rome state that ➢l. Lavadio, Don Miguel's
Ambassador, has taken leave of the Pope before his departure
for Genoa.

Accounts from Ancona confirm the catastrophe which took
place at Arta. The English Consul and the Greek Bishop
have been carried off as hostages to the mountains. The
moment the Greek Government were informed of this event
they despatched troops to the frontiers.

Admiral Sartorius has arrived at Brest.
We have received the following from Paris :

MASSACRE AT PA-RA.
(FURTHER PA RTICULA RS.)

Accounts have been received at Havre, by the ship Jose.
plane, which left Para on the 15th of May, with further
particulars of the three days' horrible events. The Portuguese,
wishing to enforce the installation of the new authorities named
by the Regency, landed from on board some vessels their crews
and the refugees, who took possession of some houses. On the
16th of April, in the morning, they commenced firing from
one of the houses on a detachment of the National Guards,
who surrounded the house. All the troops, joined by the
people of colour, with a piece of cannon, proceeded to the
houses in the possession of the Portuguese, and they were
carried, after an obstinate resistance ; those who remained
alive were massacred. The town, during two days, had the
appearance of a place taken by assault. At length, after
three days' slaughter, order was a little re-established.
