Title
[NA010I184], Technical Note, Thomas Alva Edison, January 11th, 1889
Editor's Notes
Phonogram [drawing] Rubber gives the necessary spring & allows new material blanks to be used--by slowing up phono to 1/2 speed say 60 & running over once with a .004 Recorder & returning & running again between lines 1000 words can be got on phonogram I inch long-- [next page] Kinetoscope [drawing of cylinder] If 1/8 photo taken on 3 inch cylinder Then there should be 72 parallel flattened places longitudinally along Cylinder so that all parts of photo be in focus-- glas strip could be pasted along side ends other but this is perhaps unnecessary a varnish might be used Collodion etc enamel etc
