taining the pyramidal planes 121, 358, 348, 676, 111, 656, 328, 
313, is the common feature of the crystals of the locality. In 
other crystals the zone between the brachypinacoid (010) and 
the macrodome 3(203), containing the pyramidal planes 2°12:3, 
283, 278, 268, 258, 248, 238, 223, 213, 629, all but one of 
which are new, is strongly developed; as many as nine of the 
Planes in this zone have been observed_in a single crystal. 
Figures 1 and 2 show common forms, and the projections on 
the basal planes given in figures 8 and 4 show the development 
of the two zones mentioned, as also of several other characteristic 
zones. In some cases the crystals are spear-shaped being shee 
ened off by very steep pyramidal planes; several of these do 
not admit of exact determination being rough and rounded, but 
Several of them can be made out, as /(521), A(861), and so on. 
. The most complex of the crystals are generally small, vary- 
ing in thickness from 4 mm. to 14 mm.; occasional large erys- 
ls, however, show a considerable number of planes, these 
being sometimes so rounded into each other as not to admit of 
etermination. The crystal from which figure 4 was drawn
