united amines thereby precipitated were separated by appro- 

 priate treatment with aqueous hydric chloride*. * B was 

 crystallized twice from naphtha, and thrice &c. (B 3 &c.) from 

 alcohol. 



The chlorination of acetanilide yields but little dichlorani- 

 line; the chlorination of the acetate still less. 



Monochloraniline produces great cold when dissolved in 

 alcohol. On the application of heat to its powder, it melts with 

 great sharpness,

2. Trichlor aniline. — A was obtained by chlorinating a solu- 

 tion of aniline in glacial acetate, as described under Mono- 

 cMoraniline. The product was melted under aqueous potash, 

 twice distilled in a current of steam, and crystallized twice 

 from naphtha and thrice &c. (A 3 &c.) from alcohol. 



The chlorination of acetanilide suspended in water yields 

 little or no trichloraniline. 



Lesimplef describes a modification of trichloraniline which 

 he prepared from nitrotrichlorobenzol by reduction. It has, 

 he states, a very unpleasant and persistent smell, and melts at 

 96 0, 5. On these two points my derivative differs from his: 

 it has a faint but not unpleasant odour, and melts at about 77°. 

 In all the other reactions and characters mentioned by Lesimple 

 the two bodies exhibit a complete agreement. Beilstem (who,
