The liquids employed are the liquid sulphides of calcium, or of barium; a solution of sulphate of iron is afterwards forced into the wood.

Introduce 1 dr. of phosphorus into a Florence flask, and pour over it 1 oz. of rectified spirit. Immerse the flask in hot water, until the phosphorus is melted, then put a well-fitting cork into the mouth of the flask, and shake briskly until cold. The phosphorus is now reduced to a finely divided state. This after pouring off the spirit, is to be mixed in a mortar with 1 1/2 oz. of lard. Five oz. of flour and 1 1/2 oz. of brown sugar, previously mixed together, are now added, and the whole made into a paste with a little water. Cheese may be substituted for sugar when the paste is intended for rats or mice. (There is said to be no danger whatever of spontaneous ignition, either during or after the preparation of this paste.) - Pharm Journ.
