slightly yellowish precipitate, which is insoluble in water and nitric acid,
but readily dissolves in ammonia and the alkaline hyposulphites.
Chlorine easily decomposes bromide of silver, and transforms
it into chloride.

M. Biot has expressed his opinion, that it is not possible to find
any substance more sensitive to light than the bromide of silver.
This is true to a certain extent, but in combination with
deoxidizing agents, other preparations have a decided superiority
over the pure bromide of silver.

Bromide of Gold--Is readily prepared by adding a little bromide
to the brown gold of the assayers, and allowing it to remain
some time under water, or assisting its action by a gentle heat.
It forms a salt of a bright crimson color, but in its general
properties is precisely similar to the chloride used in gilding.

Bromide of Magnesia--Is prepared in the same manner as bromide of lime.

This mixture is particularly adapted for hot climates,
and is used in this country by some few who regard its use
as a valuable secret.

Bromide of Starch.--This preparation is much used, but not alone.
It is combined with lime by putting about one part in measure
of starch to four of lime. It is prepared by adding bromine to
finely pulverized starch, in the same manner as bromide of lime.

Experiments with Bromine.--Place in a very flaring wine glass
