among lapidaries, a counterfeit stone composed of two pieces of crystal, with a colour between them; so that they present the same appearance to the eye as if the whole substance of the crystal were coloured.

The crystal or glass is first cut in the manner of a brilliant, except that the figure must be composed of two separate pieces. After the two plates have been thus cut, and fitted with the utmost exactness, the upper part is to be polished ready for setting. The colour is then put between the two plates by the following method:—To two scruples of Venice turpentine add one scruple of the grains of very pure mastich previously powdered; melt them together in a small silver spoon, add to them gradually any of the coloured substances mentioned below, in a state of fine powder, and stir them well together as the colour is put in. Then warm the doublets to the same temperature as the melted mixture, apply it to the surface of the lower plate; and put the upper one instantly upon it, and press them to each other, taking care that they be conjoined perfectly even. When the cement is quite set, the redundant part of it, which has been pressed out of the joint, should be scraped off. In the setting, the mounting should cover the joint, in order to prevent the separation of the pieces.

The colour of the ruby may be imitated by mixing a fourth part of carmine with some of the finest crimson lake; the sapphire, by very bright Prussian blue, mixed with a minute portion of crimson lake; the emerald, by distilled verdigris, to which is added a little powdered aloes; the garnet, by dragon's blood, with the addition, if necessary, of a very small quantity of carmine; the amethyst, by mixing some Prussian blue with crimson lake; the yellow...

a game on dice within tables. The men, fifteen in number, are placed thus:—Upon the six, cinque, and quatre points, there stand three men a-piece; and upon the trey, deuce, and ace, only two. He who throws highest has the benefit of throwing first, and what he throws he lays down, and so does the other: what the one throws and has not, the other lays down for him, but on his own account; and thus they proceed until all the men are down, and then they "bear," as it is called. He who is first down bears first, and will doubtless win the game if the other throws not doublets to overtake him; which he is sure to do, since he advances or bears as many as the doublets make, namely, eight for two fours.
