Near the close of this article the author records having treated 

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

 genous acid body.

 Condensation Product of 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 :

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 /^TJ_/^ ^CH : CH 2

Action of Fuming Nitric Acid on Acetoacetic and on 

 Mono-chlor-acetoacetic Esters. 



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

 C 4 H 7 O 3 N and C 4 H 6 Cl O 3 N, obtained by these reactions are oximido
