From these results, it follows that the replacement of one or both aminic hydrogen atoms of the-CO* NH, groups does not interfere in any way with the production of yellow alkali salts and violet or blue ferrous salts. The acidic hydrogen, therefore, of the oxime of mesoxamide and its derivatives is not furnished by either of the-CO* NH, groups. Further evidence in favour of this view is afforded by the alkyl-substi tuted violuric acids, monomethylvioluric ...
