THE DAGuERRoTYpE, OR SOLAR EN-.
eRAvING.-Much curiosity has been excl
ted among our artists and connoisseurs, to
ascertain the secret of Daguere's discovery
1t is very common in certain circles. We
are told, to notice fingers blackeneri by the
nitrate Of silver. We believe, yet, nom,
ofour experimenters have been able to re-
tain the color impaired to the nitrated pa
per by the suns rays. They also find their
images inverted. We have heard it in
timaled that The French government are
about to make arrangements with Mr..
Dasuerre, by which in the course of two
or three years, The beuef' of his discovery
will be impaired fully 10 the public
Within this period it is expected that the
whole matter will be found out in this
country
As usual in such cases, The credit Of Mr..
Daguerre's discovery is claimed by hust
Of competitors. Aud III truth there is evil
dence that Others have anticipated him IN
some of the principal features Of the art -
The London Aihenaum saws
The most curious fact in relation TO this
discovery yet remains TO be told. 1t would
appear, considering the character Of the
pictures. all hut impossible that impress
sions from them could he multiplied after
the manner of an engraving; VI. Daguerre.
indeed, stated to US that il was impossible,
and tits but reasonable to believe that he
is fully informed ofthe nature and extent
oflhe discoveries as NJ. Niepce himself
Yet, in 1887, M. Niepce moi only declared
that it was possible, but produced speci-
smens ofsuch multiplied copies; and Mr..
Bauer has now in his possession, moi only
copies of engravings fixed permanently by
the action of light, MOI only scenes from ma
ture, but metallic plates engraved, and en-
cravings copied from them; and he under
stood and believes that no engraving tool
was used, but that the drawings were
fixed by the action of light, and the plates
subsequently engraved by a chemicalprn
cess, discovered by Mr.. Niepce. II so,
the greatest secret of all remains yefto be
made public, and is, we believe, as eun-
known 10 Mr.. Daguerre as 10 others.
The Porkoforte "A New Musical, In.
strumen,.-The Cincinnati Sun describes
new instrument which has lately been
invented in tina. city, called Porkoforte;
and as the good people there possess The
material for manufacturing in almost any
quantity these instruments, will doubt-
less find its way into every parlor in the
Buckeye State, as well as the edges Of ne
diana and Kentucky. Those in favor Of
domestic manufactures willcertainly pa
,tronize it.
ise The instrument. as described by the
Sun, is d large, long box, flied up with as
many compartments as there arc notes in
.the'scale. Holes are then bored in the
side.bfthe box, and within each compari
ment pig is placed, with his tail extenl
ing through the hole. Outside. The n,'ru-
meni seems only curlously shaped piece
of furniture. while the tails. stuck rhrom
all in row and properly Strengthened, re
semhle very much the Keys of a piano. :
The instruments requiresyerv littlelrnutle
in tuning, since If the pigs are carefully
selected they will last for three years, ana
in the intervals always be onnd corre:i
The effect produced by This instrument i.
perfecrly unlike anv other; the crescen
do and the ciearness Of the high notes es
pecinlly are almost electrical.
