Pure French, English And American Photographic chemicals.—Heath & Brother, No. 324 Broadway, (entrance in the cutlery store,) manufacture photographic daguerreotype and other pure chemicals and apparatus.  For purity and beauty their chemicals are not surpassed; as a proof the sets of gold are fully equal to the French, as they have an experienced French chemist, who has for the past six years, devoted his entire time to the manufacture of these chemicals in Paris.  Being also practical operators in all the processes of photography, we are enabled to offer operators collodian iodized that will work uniformly, and in from five to thirty seconds, according to the wish of the artist.  Also, electric plating chemicals.
