 characterised by the melting-points of their benzoyl derivatives. The-

On treatment with bromine in presence of sodium methoxide the 

 amide gives a urethane, which on distillation with lime yields the amine. 



Aromatic from Hydro -aromatic Substances. — Kcitz and Gotz • have 

 studied the action of chlorine or bromine on hydroxyhexahydi'obenzene 

 and on hexahydrosalicylic acid, and have isolated a number of products 

 intermediate between the fully saturated hydro-aromatic bodies and the 

 corresponding aromatic derivatives. An indication of the course of the 

 various reactions may be gleaned from the following scheme : —
