analysis (using phenolphtlialein as an indicator), by E. Maly's method ^ 

 (original and modified), and by C. Gliicksmann's method (as modified 

 by J. Lauger^) are reported. 



The results are favorable to the Gliicksmann method as compared 

 with* the others tested, and this method is recommended for adoption 

 as a standard volumetric method, being especially valuable for pharma- 

 ceutical chemists.
