Show To Preserve Fabric. , German ingenuity is stated to havere- sorted to a method revived from the most ancient p.it of rendering fabrics proof aaiu t.;t- ravages of decay for an ind-rimce p?ri- i. a proc by which it is uid. n matter how delicate the tenure or color oi the f-ibric may be, its long life i3 aa.-ur.-d. Ii appears that the inventor in this cae, a German chemist, based his exp'-rimeuts on the commonly known fact that the wonderful preservation preserva-tion characterizing the headbands of Egyptian mummies is attributed to their having been impregnated with a kind of resin. Acting upon this assumption, ex-1 ex-1 periments were made with the substance : extracted from birch bark, with the re-I re-I suit that the green tar left after the oil ! used in tanning has been extracted from ' the white bark of the birch tree yields a substance neither acid nor alkaloid; and this, in solution with alcohol, forms a liquid with a power of resisting, after once becoming dry, even the action of alcohol itself, and is alleged to possess the property bo long a desideratum ol rendering textile fiabrics apparently imperishable, im-perishable, as far as decay is concerned, a peculiarly valuable property being also claimed for it, namely, a ready union with the most delicate as well as brilliant colors.
