Upper Figures. The metastatic crystallization is formed, as before observed, by a particular arrangement of the molecules. These continue to form regularly, according to the supply of those molecules, which, stopping abruptly, terminate in the obtuse point of the primitive crystal, showing three faces. This termination is not very common: the outline on the left hand will help to explain it. The other lateral faces will be spoken of hereafter.
The lower figure shows the equiaxe termination, and the right hand geometrical figure, its formation upon the rhomb.
