124. _To remove Unpleasant Odors._--The unpleasant smell of new paint is best removed by time and atmospheric ventilation; but tubs of water placed in the apartment, will act more rapidly; with this inconvenience, however, that the gloss of the paint will be destroyed. Unpleasant smells from water-closets, or all articles of furniture connected with them, may be modified by the application of lime-water, to which may be added the soap-suds that have been used in washing, which neutralize the pungently offensive salts; a little quick-lime put into a night-chair will destroy all disagreeable effluvia. Aromatic pastiles of the following composition may be burned with great success: take of camphor, flowers of benzoin, powdered charcoal, powdered cascarilla bark, powdered Turkey myrrh, and powdered nitre, each equal quantities; beat them with syrup sufficient to form a mass, and divide into pastiles of a conical shape. They may be mixed up with spirit of turpentine (the rectified oil) or anything that is inflammable. Syrup does best, as it is most adhesive. 125. _To prevent disagreeable Smells from Privies, Night Chairs, &c._--Milk of lime (water in which lime has been slaked, and which is whitened by the fine particles of that substance) must be mixed with a ley of ashes, or soapy water that has been used in washing, then thrown into the sink of the privy; it will destroy the offensive smell. By these means, for the value of a few pence, any collection of filth whatever may be neutralized. For the night-chair of sick persons, put within the vessel half a pound of quicklime, half an ounce of powdered sal-ammoniac, and water one pint: this will prevent any disagreeable odor. 126. _Remarks._--Quicklime, or even lime just slaked, answers the purpose without any addition. It is the only thing used in camps, particularly in hot countries, to keep the ditches from creating contagion. 127. _To clean Books or Prints._--Ink spots may be removed by oxalic acid dissolved in water, and carefully applied with a hair pencil. To remove oil or grease, warm the spot, lay over it blotting paper, and upon it the heated blade of a knife, when the blotting-paper will absorb the grease; then apply spirits of turpentine, with a hair pencil, and restore the whiteness of the paper with spirits of wine. 128. _To preserve Books._--A few drops of any perfumed oil will secure libraries from the consuming effects of mouldiness and damp. Russian leather which is perfumed with the tar of the birch-tree, never moulds; and merchants suffer large bales of this article to lie in the London Docks in the most careless manner, knowing that it cannot sustain any injury from damp.
