Fah.; the lime gradually assumes a beautiful scarlet color, and acquires an appearance very similar to that of the red iodide of mercury.

The chloro-iodide of lime may be formed in the same manner; it has a deep brown color.

Both these compounds, when the vapor arising from them is not too intense, have an odor analogous to that of bleaching powder, and quite distinguishable from chlorine, bromine, or iodine alone." Farther on, I have given, in connection with accelerators, a process I adopt, which is far less tedious and equally reliable.
Bromide of Silver--May be formed by pouring an alkaline bromide into a solution of nitrate of silver, in the shape of a white, 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.
