The 
crystals 
Thus the prevailing form at Kajlidongri is the combination 
of the fundamental pyramid p or (111) with the 
KajUdougn ^^^^^.^.^g^j^^i pyramid X or (421), see fig. 1. Some- 
times thin bevelling edges of r or (865) are present,

as in fig. 2, and very rarely little faces of the prism of the first order m 
or (110) shown in the same figure. Very rarely these crystals are 
truncated by the basal plane c or (001). Simple pyramids or octahedra 
are very rare and no twins have yet been observed. 
At Kacharwahi, on the other hand, simple tetragonal pyramids or 
. octahedra are common, although they often show 
crjstls. the basal plane c as well, as in fig. 3. Frequently 
the octahedral crystals are rendered more com- 
plicated by the presence of faces of the ditetragonal pyramid ij or (423), 
as shown in fig. 4.
