l-Nitro-phenyl-2-naphthylamine is insoluble in dilute alcoholic hydro- 

 chloric acid, and readily soluble in ether, glacial acetic acid, or benzene. It 

 is sparingly Boluble in cold, and easily in hot, alcohol. Its solution in cold, 

 concentrated sulphuric acid had a deep red colour.

The dinitro-phenyl-naphthylamine, which was got by heating on the water- 

 bath for three hours an alcoholic solution of 2-naphthylamine and 2 4-dinitro- 

 1-chlorobenzene, crystallised from glacial acetic acid in the form of red prisms 

 melting at 170-171 0.
