  DEVELOPING
          EASTMAN
   T\EE"FII-M.
    ORTHOCN ROTVIRTIC, NON.HALATION.
      When manipulating Eastman N. C. Film bear the follorving
      facts in mind:
         fst  N. C. Films being coated on the back with gelatine,
      neither side must come in contact with anything while drying. Note
      special directions for drying.
        2nd. As N. C. Films are very rapid and are orthochromatlc
      theyshould be handled carefully in the dark-roomwith safe rubylight,
      or developed in either the Kodak Film Tank or Kodak Developing
     Machine to avoid fogging.
             l'or No. 1 and No. 2 Brownie F'ilm we would advise the use of
      the Bnowwrn Dnvnroprxc Box or BnowNrr Frr,rrr Terr.
        3rd. N. C. Film will not cun and the glycerine bath is, there
      fore, entirely unnecessary.
        4tb. N. C. Films must be 6xed in anAcid lixing Bath, or else
     immersed in an alum bath after fixing.
            PR"EPARI.S{G FOR DEVELOPMENT.
         For best results rve urge the use of the Kodak Filrn Tank, the Brormie
       Filrn Tank, or the Brorvnie DeveJoping Box, calling particular attention'
      however, to the fact thit the Acid Fixing Bath must be used or  filrns
      must be soaked in alum bath for fully five minutes and dried as per directions
      herein. Those w4ro preder the dark-room method o{ developntcnt should, horv-
       ever, procoed as follorvs:
     We recommend the development of cartridge fil.ms in the strip' The
       operator can readily handle a 12-exposure strip (as described in Section I.)
      up to and including the 3rl x 4f   size. In the larger slzes those desiring tri
       f,llow tlre strip method of-developnrent should use the 6 exposure cartridges
        if-they,f,nd the longer oner cann,,i be conveniently handled,
               If the operatoi-prefers to cut up the cartridge fihn before dcvelopment, he
        shoulcl carefully follow the directious given in Section fI.
