the fbllowlng preparation: Sulphate of zinc, 55 lbs.; potash, 22 lbs. ; alum, 44 lbs. ; oxide of" manganese, 22 lbs. ; sulphurie acid of 60 °, 22 lbs.; water, 55 lbs. All tile solid ingredients are put into a boiler containing the water at 45°C. (113°F.), and as soon as they are dissolved tile sulphuric acid is poured in gradually until the mass is completely saturated. The pieces of wood are kept about 5 eentimetres (11"97 in.) apart, and after three hours' boiling they are dried in the open air.
