A study of Chart II will show that twelve of the twenty-two samples 

 showed a bacterial count of 100,000 or less when first received. Of 

 these twelve samples five were received during the summer months 

 and seven during the winter months. Of these five summer samples 

 we find an average of 63,890, and of the seven winter samples an 

 average of 16,382. If we omit the counts of samples III, IV and VIII, 

 all of which are from private unUcensed producers, and average only 

 the licensed producers, we find the average of the summer samples to 

 be 79,854, and of the winter 28,203. 



CHART III 



Samples Showing an Initial Coxtnt of o\^r 100,000 



Turning now to Chart III we find there are none of these twenty- 

 two samples which showed an initial count of over 100,000. All of 

 these were made during the summer months, and all were from licensed 

 producers. The general average is 797,738. 



In Chart IV, I have not only placed the initial counts of the last 

 ten samples but also the number of germs found in these milks in the 

 afternoon or evening of the same day. This will give us an idea of 

 what kind of milk we may expect to have for the evening meal, or 

 worse still, for the baby's evening nursing, under present conditions. 

 Not only that, but this chart shows what kind of milk the well-to-do, 

 who can afford ice, may have, and also what the poor, who cannot 

 afford ice, will have. I take it that it is reasonable to expect a milk 

 to be wholesome at least during the day it is received. While there
