M. Mene, a French chemist, has just discovered that hydrate of alumina, prepared by decomposing alum with carbonate of soda, is a perfect substitute for animal charcoal in the decolorizing of liquids. He has tried it on sugars, sirups and molasses, and it has given every satisfaction ; and after having been us? d once, it can be washed and re-prepared. It has also the great advantage of cleanliness ; and it is more pleasant to our fancy to know that our sugar has been clarified with alumina, than with burnt blood, and similar animal products.
