compounds of phenylamine would exhibit differences in their proper- 

 ties similar to those which distinguish alpha- and beta-nitrophenyl- 

 amine. 



With the view of deciding this question experimentally, I have 

 submitted acetylphenylamide to the action of bromine and chlorine, 

 in the hope of thus forming directly from phenylamine the bromi- 

 nated and chlorinated compounds in question. 



Action of Bromine on Acetylphenylamide. 



A cold aqueous solution of acetylphenylamide, when agitated with 

 bromine gradually added in small quantities until the yellow colour 

 imparted to the liquid no longer disappears, furnishes a crystalline 

 compound difficultly soluble in cold, but easily recrystallizable from 

 boiling water. The substance consists chiefly of monobrominated 



acetylphenylamide 



(C 6 H 4 Br) 

 (C 8 H 3 BrNO=(C 2 H 3 0) N, 



which is however invariably mixed with small quantities of dibro- 



minated acetylphenylamide 



(C 6 H 3 Br 2 ) } 

 (C 8 H 7 Br 2 NO=(C 2 H 3 0) I N. 



T have not been able to find a method of separating these two 

 bodies perfectly. 



The brominated compound is readily attacked by potash. On 

 distilling the mixture, the vapour of water carries over a volatile 

 body which solidifies in the condenser into beautiful acicular crystals, 

 acetate of potassium remaining in the retort. 



The solidified distillate was purified by recrystallization from boil- 

 ing water, and submitted to analysis. Both the combustion of the 

 base itself and the platinum-determination of the beautiful golden- 

 yellow platinum-salt proved this body to be bromphenylamine 



(C 6 H 4 Br) 

 C 6 H 6 BrN= H N. 



In its appearance, odour, and taste, as likewise in its deportment 

 with acids and with solvents generally, the brominated base ob- 

 tained from acetylbromophenylamide resembles perfectly the brom- 

 phenylamine produced from bromisatin, a specimen of which I ob-
