than 500,000 per cubic centimeter and 5.61 c. c. when the counts 

 were less than 500,000 per cubic centimeter. The average titrations 

 of the pasteurized milk samples showed even smaller differences. 

 The small differences in the average titration of samples with a high 

 and a low bacterial count show that there is little, if any, relation 

 between the alcohol titration and the bacterial count. This is shown 

 even more strikingly in Table 23, where the range in titrations 

 among samples grouped according to bacterial counts is recorded. 

 With these extreme ranges among samples of milk with high and low 

 bacterial contents it would be almost impossible to interpret an 

 alcohol titration in terms of bacteria.
