^ The empirical formulas have been calculated from the analytic results, and 

 the relations between the carbon and phosphorus, and the phosphorus and base 

 (M'), are given in these two columns. The carbon and the phosphorus are, in 

 each case, assumed to be six atoms per molecule. 



^ Placed on the market by the Gesellschaft für Chemische Industrie in Basel. 



^ A 0.2 per cent. HCl extract of wheat bran several times reprecipitated from 

 weakly acid Solution by alcohol. 



* The first substance; obtained by extracting with sodium chlorid Solution 

 and, after removing protein with picric acid, precipitating with copper and 

 removing the copper.
