tained from Dr. Hofmann's collection. There is only one point in 

 which a slight difference was observed. Both compounds are 

 capable of crystallizing either in needles or in well-defined octahedra, 

 the former being generally obtained from water, and the latter from 

 alcohol. The bromphenylarnine, obtained from the acetyl-compound, 

 appears to be more inclined to crystallize in needles than in octa- 

 hedra. Circumstances have prevented me from entering into an 

 examination of the products of decomposition of the two brom- 

 phenylamines ; and the question whether these two bodies are really 

 identical, or similarly related as the two nitro-compounds, must be 

 decided by further experiments*. 



Action of Chlorine on Acetylphenylamide. 



The phenomena observed in the action of chlorine on a cold 

 saturated solution of the phenyl-compound are perfectly similar to 

 those presented in the corresponding reaction with bromine. A 

 crystalline compound immediately separates from the solution; as 

 soon as the crystals cease to augment, the current of chlorine is inter- 

 rupted. Washed with cold, and once recrystallized from boiling 

 water, the chlorinated body is found to be nearly perfectly pure 

 monochlorinated acetylphenylamide

which, when distilled with potash, furnishes abundance of chlor- 

 phenylamine, resembling in a marked manner the chlorphenylamine 

 obtained by the action of potash upon chlorisatin.
