PHOTOS WITHOUT CAMERAS.
in a paper read at the last monthly scientific meeting of the Royal Dublin Society, Mr E. E, Fournier d'Albe, described a "discovery in photography which obviates the necessity of a camera or lens for copying black and white letterpress, woodcut, maps, plans, letters, or similar flat objects. A sensitive plate' of the kind known as "photomechanical" or process plate is laid upon the drawing to be copied in the dark room, the Him being next the paper. A gas jet is then lighted, and brought to within some three feet above the plate, and after an exposure of about half a minute the plate is developed with hydro-quinone, or with some developer giving great contrast and hardness. A faint negative of the picture is thus obtained,which is much obscured by "fog." From this negative a positive transparency is printed by contact, again with the greatest possible hardness. If this reproduction is used for obtaining a second negative by contact, and another positive is printed from this on glass or paper, a perfect reproduction of the original is obtained. Mr Fournier d'Albe proposes to call the process "Anastatic photography."
