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.

Linseed, poppy, olive, pahn and fish-oils can be successfully clarified in this manner.
