From these and other experiments described in previous commu- 

 nications it follows that the quantity of alkali, which is fixed by 

 glycine and alanine is very important. 



TABLE I. Retarding action of alanine on the destruction of galactose 

 by alkali. 



The number of cm\ alkali used for titration of the same quantity 

 of these amino acids dissolved in water (with phenolphtalein as 

 indicator) can practically be neglected with regard to the above. 



By further experiments it has appeared that glycine and alanine 

 behave under the circumstances belonging to these researches as 

 one-basic acid. 



') Before using this solution, il was boiled for a moment and afterwards cooled.
