remarkable and of obvious theoretical importance. 
Action of Hydrochloric Acid. 
In 1867, Strecker* showed that uric acid heated with fum- 
ing hydrochloric or hydriodic acid to 170° assimilates five 
molecules of water, giving carbonic dioxide, ammonia, and

Ing, glycocoll crystallized out with its characteristic properties. 
For its identification, it was converted into the copper salt by
