WALNUT HUSKS, or PEELS (Brout des noix, Fr.), are much employed by the French dyers for rooting or giving dun colours.

WINCING-MACHINE, is the English name of the dyer's reel, which he suspends horizontally, by the ends of its iron axis in bearings, over the edge of his vat, so that the line of the axis, being placed over the middle partition in the copper, will permit the piece of cloth which is wound upon the reel to descend alternately into either compartment of the bath, according as it is turned by hand to the right or the left. For an excellent selfacting or mechanical wince, see DYEING.

XANTHINE, is the name given by Kuhlmann to the yellow dyeing matter contained in madder.
