    dressed with a mineral composition (2 parts of lime to 1 of salt) instead of farmyard manure. This process also has been attended with considerable success. Pounce. Powdered gum juniper is used under this name for preparing parchment for writing on. For liquid pounce, see Ink, Marking. Poudke Clarifiante. Beat together the whites and yolks of eggs, dry them with a very gentle heat, and reduce to powder. For clarifying wines and syrups. Powders.

Prussiate of PoTAsn (Yellow). What is known in com- merce by .this name is the ferro-prussiate of potash, or ferrocyanide of potassium. It is prepared by fusing in an egg-shaped iron pot a mixture of 2 parts of pearlash and 5 parts of dry animal matters, such as horns, hoofs, tallow- chandler’s greaves, &c., till foetid vapours cease to be pro- duced. Iron filings are sometimes added, but usually the iron necessary to the formation of this salt is derived from the iron pots and stirrers. The fused mass (prussiate caJce) is allowed to cool, dissolved in warm water, and the clear filtered or decanted solution evaporated, that crystals may form. These are dissolved in hot water, and the solution allowed to cool very slowly, that large crystals may form. Bed Prussiate of Potash. Ferrid-eyanide of Potassium. Into a dilute solution of the above prussiate of potash a current of chlorine gas is passed, till the solution ceases to give a blue precipitate with pcrsalts of iron. It is then evaporated, crystallized, and rccrystallized till quite pure. [M. Posselt advises to add a few drops of solution of potash to the boiling liquor, to decompose the green matter that is formed; to filter the hot solution, to separate some peroxide of iron which is thrown down, and to let the liquor cool very slowly.] Or, hoil yellow prussiate of potash with 12 or 15 parts of water, and while boiling add good chloride of lime until a filtered sample no longer yields a blue precipitate with persalts of iron. Filter quickly, and add carbonate of potash till the liquid has a
