Show To rrpjfrie Textile Fairies. A Itelgiati chemist has discovered a means for rendering fabrics, no matter how delicate lu texture or colorjiroof against the ravages of decay. The wonderful state of preservation which the head bunds of the Kgyptiau mummies exhibit is due to their having bet-n lupreg-nated lupreg-nated with a kind of resiu. Tills led the inventor to make certain experiments experi-ments with the substance extracted from birch bark, to which tho -cculiar aroma of Russian leather Is due, and he found out that the green tar w idch was left over after thu oil used in tanning had been extracted from tho white lark of the birch tree yields neither acid nor alkaloid, and that in solution with alcohol it forms a liquid of remarkable fluidity with the power of resisting, when once driest, even tlie action of alcohol itself. Tills sulctancc will, it is fc&id, unite with the nio-t delicate and brilliant colors, and render lliem imrerishable. Et. |
