INVISIBLE INK FOR POSTAL CARDS

The following are, according to the Stationer And Printer, laid to be good recipes for a sympathetic post-card ink *. — 1. Dilated sulphuric sold— one part by measure of acid to geven of water. When tbli ink is nied the card will at irst show roughened tracea of the writing, but after being allowed to dry for a short time these disappear, and it it bb invisible as if done with water. Of course, only a gold fen or a qaill must be used. If it is desired to avoid the suspicion of using sympathetic ink, wbloh night be fxo ted by • blank postal card, it may be wrrten upon, across the first wrltirg, with tinotme of iodine, which will entirely fade out when the heat is allowed 10 develop the invisible ink 2. Use 'a solution of sulphate of iron, and develop with a solution of proisiate of potash, 8. T«ke a solution of petasslam (1 to 50); after writing with the •olotlon the otters and writing are visible to the naked eye ; but if a damp sponge be psasd over the writing, aftar It Is dfv, then it will be absolutely Invisible. The Ink may be developed in several ways. With in phate of iron the writing will appear blue, and with sol phate of copper dark brown ; the writing with ordinary ink, which it is advisable not to omit, remaining unaltered. By exposure to the fumes of muriat'o aoid, or by dipping into the same aoid, slightly dilated, the invisible writing will be developed ef a bloish green oolor, while the ordinary writing with nutcall Ink will disappear.
