of permanganate of potash in seven gallons of water (according to Mitscherlich, this product is soluble in fifteen to sixteen parts cold. water ), to this solution-which is of an intense purple color--thirty kilograms of the oil to be clarified is added little by little. The whole is allowed to stand two days, but ~is stirred very frequently. At the end of that time, four and one-half gallons of water is added and five kilograms of the hydrochloric acid of commerce, 20 ยฐ to22 ยฐ B., and the whole stirred again. After a few days, the acidulated water is carefully drawn off, the oil is treated with hot water to cleanse it from traces of acid, and is then passed through a charcoal filter. Linseed, poppy, olive, pahn and fish-oils can be successfully clarified in this manner.
