New York, Jan. 30, lS45.
Considerable sensation has been p'odu-
ced among our ensravers by the news OF
discovery, which is not only likely to
affect their Interests, 10 great extent, but
which, il generally made known, must lead
10 consequences affecting he paper cur
rcncy of the civilized vorld, the impor-
tanee Of whichit is hardly possible TO ex-
asserate. l am indebted to Mr., Chap
man. the we'll known artist, for an accoun,
of the invention, and specimen Of plan
produced through lis agency.
The discovery consists in a process by
which ain elaborate line engraving Of any
size may he SO accurately copied that
there shall be no pcrceptible difference be-
tween the original and tho copy by. which
an engraving on steel or copper may he
produced from an impression ef tae print
original gplate. never having been seen by
the copyist-and The copied engraving be-
ing capable of yielding fr5n Ten 10 twenty
thousand impressions. The producer viii

able 10 swear which was the original and
which lte copy. =,
From the speciriien in my possession,
obtained by this process, and which is'cop
led from proof engraving OF the Saviour,
from the BURN of Nj. Blanchard, from! the
painting of Delarcche. Should infer that
these claims on the part Of the discoverer
copld he fully snbstanlialed. The most
delicate touches are transferred with per-
feet fidelity, and this after upwards of four
thousand impressions from The duplicated
plate had been taken. The London pub.
Usher of The engraving submitted me of
these copies, together with proof Of the
original plate, to several artists, painters,
aud Ell sravcrs; and the opinion at which
they arrived was, thai, although it was
not difficult 10 to distinguish the original
from the copy, they ,csre so thoroughly
alike that any person of pracliced eye
mightsuppose The two1o be from The same
plate, the one being merely taken with
greater care than the. other; they were
precisely the same, line Forline, aud Touch
for touch; and this example completely
establishes the principle: They consid-
cred the invention the most wonderful and
the mos, unaccounlable that had been
mede .iG modern times in connection with
ari.
Many Eucsses have been made as TO the
f:ioAe by which this marvellous process is
effected, but as yet without result. The
process does not even infer necessity OF
requiring the print delivered as model,
which is returned unscalhed. The inven-
for is an Ensiishmati and an engraver by
profession. He has taken out no patent,
neither does he think it cxpediSntlo do so,
inasmuch as, he does, any unprincipled
person may at once adopt it. with little
probability Of the inventor being able to
prove that his process has been the n1edi.
um:by which the print has been produced
A friend of the Eauthor Of The irvetlion says
witlrIus,ice. ..There is noknowing to wha,
extensive changes in legislation il may
conduce; for, if any printed or @riHen doc
mcul can DC forged with SO much ease
and certainly 10 defy any detection, the
consequences maybe more appalling than
we care to anticipates" :. :.
The invention embraces the capacity tt
reproduce any form of letter press, or anJ
quality Of print, drawing, or Autograph
.in an unlimited quantity, in an inconceiv,
ably space of time. For instance. from
single copy Of the Intelligencer plate:
might beproduced in twenty minutes from
which impressions could be worked OF
with the ordinary rapidiry of The steam
press. The finest and rafest ensravings
may be reprinted ad fIfaitum; bank notes
may be reproduced in fac similie, wiihou'
the slightest point of difference; and last
Though Bol least, books may be reprinted
as from steerelypes, in unlimited quantity.
Indeed, the various mechanical and ottel
interests affected by this remarkable dis,
co9ery have not yet been half Enumerated
