Two items from The Textile Mercury, February 1891. The first is Hilaire de Chardonnet's description of his machine for spinning artificial silk from nitrated cellulose (collodion), covering the spinners, the water bath that coagulates the thread, the nippers and bobbins, solvent recovery (ether and alcohol) and the denitrating and dyeing of the finished silk. The second is part V of "Papers on Bleaching," on the lime sour (grey sour) and the ley boil for cotton goods, with a method for testing the strength of the acid. Two pages carry engineering figures of the spinning machine.
