| ''N - Sihbi On INDONh Ell . iCN II
A process has been discovered, accord
ing 10 the following extract f on The Lon
don Minns Journal Of J.ly % by which
a so't and useless stone becomes hard anC
valuable. This seems almost TOO much tc
believe, but We have learned to think fpict
before we express do1b!s IN relation to al
most any thing; we therefore will not toub'
these statements, yet will not promise &c
believe them wiihou. more evidence. The
writer IN the Journal says, 10 relation 10
liutchlsou's lndura,ed Sion -
We have much pleasure in observing
that this valuable material is qlletly, but
surely forcing its way in pubic es,ima Ion.
The principal materials at present operated
upon are the beautiful freestone at Caen,
IA N,rmandy, and worthless sandstone
which cfunbles between the in GERS al
Calverly Quarry, Tonbrd.e, Kent, but
which, as sc have before stated 10 our no
tees On the subject, is rendered as hard aud
Jarabe as granite. The paten,ee, TO whose
long persevefing ehJris must be sscribed
the perfection 10 which the processes are
brought, still, 10 the most handsome man
ner, publicly declines the merit due to the
original invention. 1t was first discovered
by VI. Charles L. Gpux, Of Bayeux, Nor.
mandy, aud of whom Mr. Hu.chison pur.
chased the brepet d'inreation which had
been taken on, for Fsance, and has since
taken out patents Tor III aud other coun
tries. We ihiuk the merits of the sub.
stance produced are now generally b.com
ing Known 10 the pub nc; and as time con.
tinues 10 give additional proofs of its econo.
my aud the perfect inds.rucllbIny Of tue
materials, aud as probibly still further I'D
ptosenenls may be made IN colorlng during
The indura'ing process, rendering II more
applicable than at pfesen, 10 the fiaer works
Q. art, It 10 likely TO become one Of the
most valuable discoveries Of this ex,raordi
nanly incentive age. As We have SO often
July described the processes aad their
effects, i, would be supeifIous for US on
his occasion TO repeat them. To show,
however, tina, our favorable opinions are
July borne out by others, we give the fol.
lowing from the Susser Express.
- illyns heard much ot Mr.. Hu,chi.
sous method of Iudura,ing stone, we we're
induced 10 visit his works a, Jack Woods
SprIn. on Tuesday last. We had been
prepared 10 expect 10 find that the stone
which had been subject to the process of
ndufaion had been completely me,amor
pho,ed bu, We mus, confess We we're not
prepared TO seq The soft stone al JIck
W Gods, which IA Its natural state crumbles
% powder with the slightest pressure be
ween the thumb and tinser, rendered a 5
iard as granite or marble. Several pieces
hat we're shown US were close limitations I
II various kinds Of The most beautifully |
grained and black marble and as BY this |
process 1t IS rend .fed absolutely Imperisha !
Die from atmospheric action, and capable Of |
eceivins the highest polish, We can, with.
'ui the slightest hesitation, accord 10 MIR. !
iulchson The merit Of mnkIng one Of the ,
most extraordinary discoveries Of tie pres
nj aye. The soi.es, stone, chalk, WOOD,
,apef, Il can be rendered as hard as metal,
10 that The most useless rubbish can be .
u'neo TO the mos. valuable purposes and,
o crown ell the cost much lower than any !
,iher that has hitherto been introduced for I
purposes TO Which 1t can be applied. or
course, IN the space Of a newspaper para
,taph, 1t would be Impossible 10 enumerate :
hthe Of the bentfi 5 this discovery is like
y TO confer on society but from the infor.
nation VIC gathered while inspecting the
'oIhs, We consider It highly deserving the
tten,Ion OF engineers, architects, scul p,ors,
'uilders, and even Of surveyors Of high
