Progress Or the Exhisltion-Descrihtion ol
Articles.
A rather amusing incident occurred at the Palace
yesterday. new order has within the past week
been issued by the directors for the security of the
ARTICLES On exhibition against the light fingered
gentry, who are generally attracted to such public
places. The police, however, have been 60 vigilant
as 70 give those individuals opportunity for pro-
scouting their business within the limits of the
Palace. According to this order, no person is aowad
10 leave the building with package or bundle of
any hnd. unless provided with pass or certificate
irom one of the managers or superintendents.
Yesterday, one of the visters, who was evidently
gnorant of the existence Of such an order was OBJ
served by one Of the policemen to have an unusual
extension OF one his pockets. The officer, fearing
that something was wrong politely requested him to
step into the ofce-a request which was acceded to.
When in the Office the vsiter was informed of the
order, and, after some hesitation, produced three
articles from his pocket, two of which were books
and the third rum bottle In reply to question
by Capt. Leonard, he said that he had come from
Maine, but he did not inform him he had obtained
the bottle there.
We mention this incident to save other visiters
nom any annoyance to which they might be subject
oy taking packages into the building.
Several pieces Of new statuary have been placed
on exhibition since last article that the dis
play in this department Of the fine arts is already
most complete. There is, as yet, much more to
arrive, however The number of paintings displayed
is Of course limited, and will remain SO till the gal
leEy is N readiness to receive them.

PHOTOGRAPHS, OR DAGUERREOTYPEs, ON
PAPER.
Long before Daguerre published his discovery
that iodized silver was affected by the solar
rays, and by their reflection from objects on it
produced copies Of them, experiments had already
been made to produce impressions of different OBJ
1scts on paper, prepared with chloride Of silver by
means of a solar microscope or camera obscura.
The impression produced was socalled negative
picture, on account Of the lights and shades being
reversed-that is the light parts were dark and the
dark ones were light-which was produced by the
decomposition Of the chloride of silver The fixing
of the pictures was effected by means of concen-
trated ammoniac, which dissolves the undecomposed
chloride of silver. To produce positive pictures
from those negative ones, another piece of paper
was prepared with chloride of silver, and the mega
tive picture placed the top Of it, both put under
glass and exposed to the light. After some hours
an impression the last prepared paper is visible
with light and shade as in nature. These impress
|sions were also fixed in ammonia. But as it took
sometimes one hour to get the negative impression,
was not much used.
The greatest difficulty to overcome was the pro-
adction of another chemical preparation Of silver,
(which worked quicker than chloride of silver and
|another agent to accelerate the action of light.
|Herschell used sulphate of iron. When he had
|exposed his prepared negative paper a sufficient
|tme in the camera, he took it to dark place
and there put it in solution of sulphate
| Of iron, which brought the picture out in
strong tints. But it was left to Mr.. Talbo
10 improve the art Of photography Mr.. Talbot in
l839 shortly after Daguerre made known his method
| Of daguerreotypng, made statement Of his
Photographic process to the Royal Academy OF
Londen He used paper prepared with iodide of
silver which, before putting in the camera, be made
sensitive by solution Of nitrate of silver, gallo acid,
and acetic acid gacias. After taking the negative
paper from the camera, nothing was visible, but by
washing it with gallic acid and little acetic acid,
he picture became visible then it was fixed in
1yposulphate of Soda As paper is very imperfect, Mr.
Talbot used albumen, spread on glass, and prepared
ike the paper, which gives excellent pictures. For
positive pictures, chloride of silver is generally used
American, English French and German chemists have
ied to improve this art till views and portraits
produced which will compare with daguerreotypes.
As albumen retards the photogenic action, different
Aher preparations have been used in its stead, such

ion Of the whole process would be too minute and
edious to render it interesting to the general reader
The pictures are preferred by some to the da
uerreotypes, as they be seen by any light, and
re easily finished like oil or water color paintings
lYnong the American daguereotypes we find da-
uerreotypes on paper, called crystallotypes by Mr.
vhipple, Of Boston. They are the most perfect Of
1er kind that have yet seen, and present varied
election Of views and portraits. These, however,
ave been copied from daguerreotypes In addition to
lese are a number of others, called sologaphs," !"
xhbited by L. G. Hawkins. They are both plain
nd colored, and are well executed.
In the French department, we find photographs
Blancard & Everard, who have done much
improve the Photographic art. They repre-
