Vegetable textiles are said to be thoroughly clcaiand bleached by immersion, at ordinary temperatiin a bath containing an alkali hypochlorite and a body. For example, for 100 kilos, of drycotton, the bath may consist of 500 litres of sodhypochlorite solution (containing 0*3 per cent, of availchlorine) to which has been added 10 litres of Turred oil or castor oil soap (containing 75—80 per centfatty acid). The treatment is complete in two or t!hours.—T. F. B. Mercerising, and Apparatus therefor. W. Indigo White and Diamine Blue IIP. With Aniline Blackthe unmercerised material absorbs a little more than themercerised. If the cotton I mercerised after dyeing,it becomes darker in shade ; this may be partly due tothe contraction.—A.

The effect of repeatedly mordanting silk with tin hasalready ben described by the author (this J., 1003, 1344).As the result of repeated passages of silk through ironand chrome mordants, fixing and washing between eachtreatment, it was found that the amount of mordant(calculated as oxide) taken up by the fibre, decreased withsuccessive passages, the decrease in the case oi the chronicmordant being much more rapid than when an ironmordant was employed. With alumina mordants, theincrease in the ratio of alumina to fibre was very slightand irregular with successive trea
