A good pejitone for this pnr]iose must lie white, without 

 odor, entirely soluble in water, eS])eciaUy on warming. 

 The water solution must be clear, colorless, neutral or 

 slightly alkaline, foamy on shaking It must ,gi\-e a vio- 

 let reaction with Eehling's solution, wdiich does not 

 change on boiling. It must give no nitrite reaction with 

 Griesz reagent, and finall\- must give, after about 5 min- 

 utes with Diplienylamine, a faint but distinct narrow, 

 clear blue ring.
