use of, which is called duplicate paja this`•ia
made by thinly • sintarieg any kind of thin paper
with any kind of oil ; hut preferring those kinds of
nil which are least liable to odyeuizeusent,or to be
evaporated by beat. The ink used in this case
consists of carbon, 'or any other colouring sub-
stance, and finely leVigated with any kind of oil.
This ink is to be evenly spread on leaies of thin
paper, &e. after which it should reiriain for live or
sox weeks, or any shorter period. betwixt Ames of
almorlient or blotting paper ; afterwards it is fit for
use: this is called curbouated paper. But any
colouring matter of any kind may be used,
prtiviileil the madiam be such as will admit of
Me' colouring matter being transferred to the
duplicate and the writing paper; and some co-
louring substances may be used without any me-
ditini or vehicle. The pees or styles used are
Made of agate, ground and polished to 'it smooth
round point, and set in metal, or any other sockets,
or any hard substance may be substituted fur agate.
To write singly by this mode, a leaf of this car-
bonated paper is laid upon a smooth tablet of
metal; secondly, a leaf of carbonated paper up-
on that, and thirdly, noon both, • leaf Of dapli.
cate paper, and upon the paper so dispoeed, the
writing is made with a style. The effect pro-
duced is • double tratater of the carboti from
the carbonated paper, viz. that en the lower surface
to the letter paper beneath, ill'd that front the
upper to the under surface of the duplicate paper
Above it. If desired, the tablet ii.ay be left out, yet
the i preeiitin is alwaya stronger with it. Duplicates
may also be made by•subsiituiiiig any dim paper
for the duplicate paper, and writing upon it with
any hurl substance, which will leave a trace !be-
hind it; or by using imelt papers a, admit of an easy
absorption of the colouring matter beileattli.
To multiply copies flout en originel, a set of
types, mid a type tablet is used ; slid far shortening
the hood% riting, the types Vail be reduced to one
figure, namely, to a point, but more figures may be
used if couveMent. These :aya ey the idea of ally

wise marked w the writing paper, which square is
called the basis of the letters, and the paper, chu-
asetav-paper ; the precise slistpe red size •thertrof is
not of importance, hut may be varied at pleasure.
The types consist of small tubes or dlettil, or any
1 other material, of any shape : on that end
which is to give the Calla of the letters, thine
may be either a routel point, or (my other airuple

wire, es may be thought proper. 'ltie type-tablet

terial of any dimensions, otrforuted with• holes or
sockets to fit the types. On the top or the type.

ing with those upon the character paper. on which
the writing or printing is to be made. To pre-
vent the accidentul shifting of the types is their

is fixed at the bottom of it. so as to taunt the
types being premed to any given distance through

are stopped. To fix the types previous to taktrig
off impreasams, melted lead, or lUly other sobs

which are vacated by the depresouts of the tyoes

bonated paper may be laid alternately upon each
other, and upon this the stereotyped paper is
pressed iii Inv way found convenient; and, by
this meitita,. with • single pressure. a multipli-
city of impressions are formed at once. To

layers of duplicate paper are taken. on which is
stamped, or printed, she basis of the letters; be-
tween
every two leaves • leaf of carbonated paper
is laid, and over all the rest the type-tablet, each
square of which must he exactly over the squarer.
or figures, in the character-paper; when thus laid,
each type which may be required to snake an im-
pression, is pressed down, from a hieh act nix copies
are produced on the papers underiwath ; and then
the types are formed its before directed. with lead,
• sterechyped tablet is formed, from which other im-
pressions nosy be inaltiplied at pleasure.
After ineltuig out the lead, the types may be all
refill/iced in their respective sockets, by gently press-
ing upon their points a metal or wooden tablet.
which will cover the whole of them at once.

Monday night, a boy belonging to a retail linen-
draper's, in Holborn, went from his master's shop
to bring some goods from a whnle.alr,haper's in
the City. As he returned with his load near Fleet
Market, he became tired. A num offered him his
assistance, giving him Is new hut to hold, and taking
the load to curry it for lain. In the mum of a few
minutes soother matt met the boy and threw a hand-
ful of smelt in his eyes.• The poor fad was then
surromidad with a set of 'fellows. who with i great
air of simplicity inquired of him whet wan the mat-
ter, toot several other quiltiouii. until the Ain with
