Horse power has hitherto been vario1sly applied

but there is novelty aud promise in the invention

ton h it.
TIE PATENT lMPULs0RIA--This ingenious
means Of applying animal power 10 the working
Of railways so as to supersede the costly loconoo
tive engine, has lately been invented in Italy. and
exhibited expermentslly upon the South Western
Hallway. 1t consists in introducing the animals
INTO hind OF coach, called impuls0na, by which
they transmit their acting power TO the leading
wheels. This '-''a-tnlsson 10 conveyed BY A very
s'--ric means, rendering useful both the drivin,
power OF the animals and their own xeisb, To

horses are 10 be worked always az their qaslte
speed, even at sixty miles an hour, without ever
altering the usual walking pace OF the horses, which
are inside the Impulsoris, on the floor Of room,
sheltered from the weather
The importance of introducing the horses into
the carriage in order to get more speed from the
surplus OF the acting power had been long thought
OF and the principle has been several times at
tempted in England France, and Italy, but hther-
TO without success
Inc new machine. whqae inventor is Signor Gle
mente MssseIano, from pignero, Piedmont. has
been Drought from Italy to England, and deposited
at the Nlne-elms terminus of the South w estern

they work it very well the pedtreila. More

ally drawn by II up the very inclined line of the
station. For working it up and down the station,
awsgon is fastened to il, when it attains a speed
OF seven miles an hour. in the experiment 10 be
made on the great line, II is expected TO gain q
speed of from fifteen TO twenty miles hour; and
tits calculated that an engine OF two horses more
will run at speed superior to that Of q steam
engine but the driving horses do not change drec-
ton or movement They can instantly be stopped
while the horses continue to walk on the peiirela
without transmitting motion 10 the leading wheels.
By the simple manner in which the horses exer-
else their moving power on the new machine, they
can work easily the usus time commonly about
eight hours a day. Daring these sight hours the
Impusoria run at least over thirty miles eight
times and as four horses do not coat much more
than two shillings each per day, il would be ex-
pense Of eight shilngs only, instead Of &c on &C
count of coke only, the cost Of which is sixpence
each mile run.
Such economy is Of the utmost importance to the
numerous interests engaged in the railways, sub-
ject 10 enormous working expenses. According to
the statements by DR.. Lardner, 10 his valuable
work on Railway Economy the locomotive
power and rolling stock absorb always more than
half, and often four hfths of all the working ex.
penses. But the principal advantage Of the new
machine will be TO afford very cheap lOoomoton on
all branch lines, thus extending the advantage OF
the railway to localities hitherto imprastcabe from
the expensive moving power.
The directors of the South Western Railway
were the first to receive the lmpulsoria on their
lire WHARF they have granted sgary facility To its
| ingenious inventor; for which courtesy he has
especially to thank the engineerin-chiefo of the 10
comotiye department Mr.. Gooch and his assistant
