were not oxidized by manganese dioxid. It oxidized amids to nitric acid both 

 in neutral and allialine solutions at boiling temperature, but not at a tempera- 

 ture of 30° C. Amido acids and acid amids were not affected under these condi- 

 tions. Uric acid and its derivatives xanthin and hypoxanthin were not oxidized. 

 Only a trace of ammonia was observed. The oxid at ordinary temperatures 

 under the conditions of this experiment did not convert organic nitrogen into 

 nitric nitrogen.
