An exceedingly hard and heavy wood, susceptible of a fine polish. There are many kinds of ebony; the most usual are the black, red, and green, all of them the product of the island of Madagascar. The black ebony is preferred to that of any other colour, but it is not so much in request as formerly, since the discovery of so many ways of giving other hard woods a black colour. This may be done by boiling smooth, clean box wood in oil till it becomes perfectly black; or by washing pear wood with aquafortis, and drying it in a shady place in the open air; after which common writing ink should be repeatedly passed over it, and the wood dried in a similar manner till it acquire a deep black colour. It may then be polished with wax and a woollen cloth, which will give it a fine lustre. An excellent black is also produced by first applying a solution of copper and aquafortis, and afterwards brushing the wood over with a decoction of logwood.
