To Clean Ivory.

Wash the ornaments well In soap and water, using a soft toothbrush to remove the dust from any fine work there may be upon them. Dry them by laying them in bright sunshine, keeping them constantly wet with soapy water for several days while they are In the sun. Finally wash and rinse them again. Never let them get dry, or the heat will cause the Ivory to warp. If the ivory is much stained, but not very deeply, rub the surface with finely ground pumice stone and water, moisten well and lay in the sup to bleach, as above recommended. If this does not succeed, wash tlfe knife handles or other articles with one part of nitric acid and ten parts of water. Polish with very finely powdered whitening made Into a paste with vinegar.
