B = 85° 47’. 
Forms observed: 6 = {010}, predominant; 
m = {110} and a= {100}, well reflecting. In 
the zone of g={011}, s = {012} and c= {001}, 
the angular measurements ordinarily are not 
so accurate as in the other zones; commonly 
g = {011} is the best developed. The aspect of 
the crystals is that of thin plates parallel to 
{010}.

The specifie weight of the erystals at 17° C. is: 1,107; the 
equivalent-volume therefore: 205,06. The topical parameters are: 
vp: o = 2:73192-10,1861 -. 7.3890. 
On {010} the extinction-angle is 43° with respect to the direction 
of the c-axis in the quadrant behind. Probably the optical axial 
plane is parallel to {010}.
