Abstract.
In this paper (which was fully illustrated with experiments) the author traced the progress of photography up to the present time, giving a full account of the new platinum process, by which pictures that are not affected by heat, acids, or light, can be readily produced, and which resemble mezzotint engravings rather than photographs.
