الصفحة 156 - Write with a solution of muriate of cobalt, and the writing, while dry, will not be perceptible ; but if held towards the fire, it will then gradually become visible ; and if the muriate of cobalt be made in the usual way, the letters will appear of an elegant green colour.
الصفحة 92 - If a piece of bright silver be dipped in a solution of sulphate of copper, it will come out unchanged : but if the blade of a clean penknife, or any piece of polished iron, be dipped in the same solution, the iron will instantly put on the appearance of copper.
الصفحة 40 - When any thing is to be gilded, it must be previously well burnished ; a piece of cork is then to be dipped, first into a solution of salt in water, and afterwards into the black powder ; and the piece, after being rubbed with it, must be burnished.
