Manufacture of Maltose. — G. R. J., 



New York, desires information as to the 

 manufacture of maltose. After makmg 

 the general statement that when any 

 starch paste is treated with diastase or 

 with malt extract, the starch hydrolyseSj 

 not to glucose, but to maltose, we refer

 Baker and Day (T^e Analyst, 33-1908-

 ten years old. As to the green precipi- 

 tate occurring it is due to the formation 

 of isonitroso-antipyrine and is largely 

 prevented if the spirit of nitrous ether
