Examples

    Photographic Reproduction Processes

  • As pointed out by Mr.B. J. B.rnett (see Introduction), many photographic processes can be devised by basing them upon the various chemical changes, of which uranous oxide, reduced by light from the uranic nitrate or sulphate, is susceptible by means of metallic or organic reagents.

    Photographic Reproduction Processes

  • Uranium forms two families of salts, uranous and uranic; corresponding to the oxides UO_ {2} and UO_ {3} respectively.
