ARTIFICIAL IVORY.
Until recently the substitute used for artificial ivory has been obtained by injecting white wood with chloride of lime, under strong pressure. Within a short time, however, it has been established that a substitute may be prepared with bones of sheep and waste pieces of deer and kid skins. The bones are for this purpose macerated and bleached for two weeks in chloride of lime, then heated by steam along with the skin, so as to form a fluid mass, to which are added a few hundredths of alum ; the mass is then filtered, dried in the air, and caused to harden in a bath of alum, the result being white tough plates, which are more easily worked than natural ivory.
