In each case, a sinnle precipitation of tlie caseine and fet for the 

 purpose of determining the sugar was made ; but the solution was 

 titrated at least twice, and the average of the results, which never 

 varied more than a cc, taken as the amount of sugar. 



This method of determining the sugar has been condemned by many 

 chemists; but, if the precaution is taken of pi'eparing a fre-^h solution 

 every time a series of determinations are made, the results will, so far 

 as I have experimented, be found to be comparable with each other, 

 and those determinations made in the same sample of milk will agree 

 very closely with each other.
