VICTORIAN MINERALS.—CASE XIV. 
another crystal, though the apices of the two sides of the fracture are 
perfect crystals themselves. 
Another has the appearance of having been 
broken in half, slipped, and been re-cemented ; but such is apparently not 
the case, as both parts show the terminal planes of the pyramid along 
the line of 
junction. In both these instances, however, it is probable 
that the faces have grown since the fracture. 
Several crystals show the 
central one projecting through the base of the prism of the external 
one, and a transverse section’ through both crystals exhibits a series 
of concentric hexagons.

: Many other minerals, such as schee- 
lite, garnet, molybdenite, iron pyrites, 
&c., occur in these quartz crystals. (See

These perfect crystals occur, in small 
patches, in various reefs, and are gene- 
rally loosely cemented by oxide of iron.

_ These occur in a large Elvan dyke 
in the Lower Silurian rocks. Their 
form is a combination of the double 
six-faced pyramid and the hexagonal 
prism.
