• "The usual method is, however, to dissolve the camphor in the least possible quantity of alcohol, and sprinkle the solution over the dry pyroxyline, which is then covered with a second layer of pyroxyline, and the whole again treated with the camphor solution, the addition of pyroxyline and camphor solution being repeated alternately until the requisite amount of celluloid mixture is obtained."
• "The pyroxyline was the di-nitro-cellulose (or possibly the penta-nitro?), and the temperature was below the igniting point of this material (40° C. would have been a better temperature)."
• "By mixing certain proportions of ammonium iodide and cadmium bromide, or an iodide and bromide of cadmium with collodion -- which is pyroxyline, a kind of gun-cotton dissolved in ether and alcohol -- a plate of glass is coated, and before being perfectly dry is immersed in the nitrate of silver bath."
