(6.) OCTOCUPRIANILINE ACETOMONOBROMIDE, 



Cu3(CeH,N)x6Br(C,H302)i5. 



This, tlie last compound on the list, is formed with great ease when- 

 ever a large excess of cupric acetate or acetic acid is added to cupric 

 bromide in alcoholic solution and aniline is added to the mixture. It 

 separates after about twenty-four hours as a fine bluish or brownish 

 black powder, whose properties resemble very closely those of the pre- 

 vious compound.
