No distinct cleavage was found. 
The optical axial plane is parallel to {010}; on c and a both an 
optical axis emerges excentrically. 
The specific weight of the crystals is: 1,555; the equivalent-volume

§ 11. IX. p-Toluene-sulpho-benzylamide. 
Structure: 
CH; 
(a 
$0, -NH—C,H; 
From a mixture of ether and alcohol the compound crystallizes 
in large, colourless crystals with varying aspect. It melts at 113°C. 
The crystals are well built and allow exact measurements.
