The supply of English wheat on sale here today was
very moderate. The trade, however, ruled heavy for all
qualities, at from is to fully 2s per quarter below the rates
current at the close of last week.

With foreign wheat the market was but moderately sup-
plied. For all descriptions the demand was in a sluggish
state, and prices had a downward tendency.
Floating cargoes of grain were in limited request, at
barely late rates.

The season for malting barley is now over. Grinding
and distilling qualities met a slow sale, at previous quo-
tations.

Malt sold heavily, at late rates.
Oats, the supply of which was moderately good—were in
slow request. at barely stationary prices.
Beans and peas supported Monday's currency. The show
of samples was limited.
In flour only a moderate business was transacted, oz%
former terms.

BOROUGH HOP.
Our market is dull, and prices have a downward ten-
dency. The accounts from the plantations are very
favourable,

obtained his impression on gelatine as above described, uses
called
it as mould which he covers with plastic porcelain,' on
which consequently the sunken parts are brought out ins
relief. The
plate thus prepared is then coated with a thin
coloured enamel, and then baked in the oven. The picture
thus comes out very distinct, the fusible enamel having
mostly run into all the depressions. which here constitute the
shades. The lights, however, not being pure, this is reme-
died by grinding off the enamel carefully on the spots re-
quired, until the porcelain is uncovered. This done, the plate
is once more enamelled with a colourless glass and again ex.
posed to the action of the fire—M. Kaiser, a Dutchman,
proposes the following dry collodion process :—A glass
plate is covered with collodion containing no bromide, but
known to yield good impressions by the ordinary methods..
It is exposed to the action of the silver bath, then washed
with filtered rain water, and afterwards with a mixture:
of half a gramme of camphor, 100 cubic centimetres,
of absolute alcohol, and two of acetic ether, so that
none of the water of the previous washing may
adhere to the plate. For this purpose the liquid is
elo.vly delivered to the plate by one of the corners, and
allowed to run oil at the opposite one, driving the water
before it. The plate is now left to dry, protected from dust
and all impurity. In order to develops the print he uses
a solution of -- 1 gramme of pyrogallic acid, 2 do. of citric
acid, dissolved in 100 cubic centimetres of distilled water,
and a few drops of a solution of nitrate of silver at 6 per
cent. The plates thus prepared may be preserved a month
without losing their sensibility, and may be dos eloped
several weeks after exposure to the light,
