Forms Observed: im = {110}, the largest developed of all forms; 
a = {100}, narrow, and r = {101} yet smaller; 
0 = }111}, small, but yielding good reflexes. 
The aspect of the crystals is that of long 
needles or prisms parallel to the c-axis.

Perfectly cleavable parallel to {101}. 
As the crystals were in every case dull and 
curvi-planed, more exact measurements appeared

The extinction on a was normally, on m obliquely orientated with 
respect to the edge a: m. 
The specific weight of the crystals was: 1,485 at 16° C.; the 
equivalent-volume is, therefore: 154,21, and the topical axes are 
calculated at: y: : w = 7,5664: 7,1910: 2.8390. 
§ 6. IV. p-Toluene-sulpho-methylnitramide. 
This compound, which possesses the structure: 
CH; 
Za 
Sige 
SO, - Near 
and melts at 60° C., crystallizes 
from a mixture of ligroin and 
ether in almost colourless flat 
needles, or in thick, short prisms. 
They are well built and give 
good reflexes. 
Monoclinic-prismatic.
