Note 104 — Chapter XIII · DELIMING, BATING, PUERING AND DRENCHING.
Reading edition
Mr. Wood has found that in many cases it is unnecessary to start afresh at the end of each week, but that additional quantities of erodin solution with the accompanying bacterial culture may be added continuously to the stock-tub as required. In puering, the concentrated solution from the tub may be diluted with 4 to 6 times its volume of warm water. The diluted liquor should usually only be used for one pack of skins.
