To quickly assess the difficulty of the text, read a short excerpt:
This copying paper is used in the same manner as the last, and fresh eggs only must be used in its preparation, because stale ones soon cause the copy to change and blacken all over from the liberation of sulphur, which unites with the silver. The colour of the copy is sometimes improved by a solution of hot potash, and by dipping the well-washed picture, after the use of the hyposulphite of soda, in a very dilute solution of hydrosulphuret of ammonia. Third Experiment. In the Daguerreotype pro...cess, a silver plate, after being thoroughly cleaned and polished, is exposed to the vapour of iodine, and is thus rendered so sensitive that it may be at once exposed in the camera. In the Talbotype process, the same principle is apparent, and paper is prepared by first covering its surface with iodide of silver, which is afterwards rendered sensitive to the action of light by means of au excess of nitrate of silver, as follows : One side of a sheet of selected Cansan's paper is first covered (by means of a spreader) with a solution of nitrate of silver (thirty grains to the ounce of water), hung up in a dark room and dried; it is then immersed in a solution of iodide of potassium of five hundred grains to a pint of distilled water, for five or ten minutes, and immediately changes, to a yellow colour in consequence of the pre- cipitation of the yellow iodide of silver ; it is then well washed with plenty of water, and being dried, may be kept for any length of time, and is called " iodized paper.
