coloration in No. 3, it was evident that the hydrolytic action was 

 proceeding more rapidly in this than in any of the other solutions. 



After three and a-half hours — Nos. 1 and 2 — deep violet reaction. 

 No. 3 contained only a trace of unconverted soluble starch, and no 

 erythrodextrin. 



Nos. 4 and 5, violet reaction, but much lighter in tint than 

 Nos. 1 and 2. 



After the digestion for three and a-half hours at 40°, and lying in 

 the cold for sixteen hours longer, the various liquids were fully 

 analysed. The corrected results are here given : —

Upon calculating the composition of the transformation products 

 from the above numbers, a very remarkable fact was brought to light. 

 Maltose was present in only one case, that of No. 3, the whole of the 

 cupric-oxide reducing body consisting in the other cases of dextrose. 

 The percentage composition of the products is here given.
