NOTE. " Barfoed's Solution. Make a solution of neutral acetate of

 this solution add 5 c.c. of a 38 per cent solution of acetic acid. 



Fehling's Solution. Solution A. 34.64 grams of pure crystalline 

 cupric sulphate are powdered and dissolved in 500 c.c. of distilled water. 

 Solution B. In another vessel dissolve 173 grams of Rochelle salts 

 (sodio-potassium tartrate) in 100 c.c. of pure caustic soda, sp. gr. 1.34, 

 and add water to make 500 c.c. Keep the two solutions separate in 

 stoppered bottles, and mix them as required. On mixing equal quanti- 

 ties of A and B, a clear deep blue fluid is obtained." Stirling's Practi-
