It was a thread so slender that it might have been spun by a miscroscopic spider. Three feet farther away was a camera with a moving film of sensitised material, the turning of which was regulated by a little flywheel.
Upon this I concentrate a pencil of light which, when reflected, acts photographically upon a sensitised moving tape in this little box, and perfectly registers the minutest movement of the receiving diaphragm. How I develop, etch, and reproduce this record, and transform it into a record of the ordinary type, you will see in due time and will kindly keep secret for the present.
As Kennedy gave a few final touches to the peculiar apparatus on the table, the cylindrical drum before us began slowly to revolve and the stylus or needle pressed down on the sensitised paper with which the drum was covered, apparently with varying intensity as it turned. Round and round the cylinder revolved like a graphophone.
Quite suddenly, then, the idea flashed through him how do they come, these odd revelations, when the mind lies receptive like a plate sensitised by anticipation? that they were waiting for a certain date, and, with the notion, came Mansfield's remark about "the Night of Power," believed in by the old Egyptian Calendar as a time when the supersensuous world moves close against the minds of men with all its troop of possibilities.
The reel is hung by its axle over a great trough containing gallons of developer, so that the film wound upon it is submerged; and as the reel is revolved all of the sensitised surface is exposed to the action of the chemicals and gradually the latent pictures are developed.
As long as it was solely a question of clandestine knowledge and ingenious surmisings, Laura went merrily with the rest: here no barrier shut her off from her companions. Always a very inquisitive little girl, she was now agog to learn new lore. Her mind, in this direction, was like a clean but highly sensitised plate.
By producing a "photo-relief" in gelatine sensitised with bichromate of potash, and afterwards exposed first to the sun and then to the action of water an impression in plastic material can be secured, from which, with the use of warm, thin, pigmented gelatine, a hundred copies or more can be printed off in a few minutes.
His negative was so emphatic as to convince the Court. I had scored the crucial point and felt, now my supreme difficulty had been subjugated so conclusively, that all was plain sailing. It was only too evident that everything had turned upon that short length of unexposed film, and I felt devoutly thankful to Providence that the light had not accidentally penetrated to the sensitised surface.
White spots on the photographic print come out as black spots here on the sensitised paper over which this stylus is passing, and vice versa. In that way you can see the positive print growing here before your very eyes as the picture is transmitted from the negative which Clark has prepared and is sending from Chicago." As we bent over eagerly we could indeed now see what the thing was doing.
Truth is like a photographic sensitised plate, which is equally ruined by over and by under exposure, and the just exposure for which can never be absolutely determined. Surely if disuse can be credited with the vast powers involved in Mr.
