Near the close of this article the author records having treated 

 acetoacetic ester with hydroxylamiu and obtaining a very stable, nitro- 

 genous acid body.

 Condensation Productof Phenanthraquinone with Acetoacetic Ester. 



These substances will condense in presence of either ammonia or 

 an alkali, preterably the latter, to form phenanthroxylene-acetoacetic 

 ester which is : —

 Cs H4— C : C<QQ^ Q^ ^5. It decomposes at 184.5 -185.5 

 C6H4-CO 



It was reduced by hydriodic acid by which the acetyl oxygen was 

 removed giving phenanthroxylene-isocrotonic ester. This was dis- 

 solved in an alkali and by adding an acid another substance was pro- 

 duced which was : — ^ tt oxt r^ ^CH : CH2 



C6H4-COOH 

 The investigation is being continued.

Action of Fuming Nitric Acid on Acetoacetic and on 

 Mono=chIor=acetoacetic Esters. 



The author has decided after further study that the two compounds, 



C4 H7 O, N and C4 He CI O3 N, obtained by these reactions are oximido
