error when he assigned, fiirfurol as the cause for the reaction obtained with 

 Hehuer's modified method and sugar, and that iu all probability the latter con- 

 tained traces of formaIdeh5'de which did not give a reaction with the less sen- 

 .«ltive Rimini's reagent. Ramsey and Trillat's finding in regard to the produc- 

 tion of formaldehyde by caramelization of cane sugar was verified. 



Where formaldehyde was added to the juice for the purpose of preservation 

 the ultimate products all contained a certain amount of formaldehyde, which 

 however was minimal iu the first sugar. It is therefore evident that all the 

 formaldehyde does not boil away in the manufacture of sugar products. 



A modification of the Hehner-Richardson formaldehyde test was made by 

 substituting peptone for the albumose.
