1 Morning's milk. 



Average of all samples, 249. taken on 12 farms was 135.146 bacteria per cubic centimeter. 



Average of 173 samples of night's milk taken on 12 farms was 115.135 bacteria per cubic centimeter. 



Average of 76 samples of morn trig's milk taken on 9 farms was 180,696 bacteria per cubic centimeter. 



The samples may be grouped according to the number of bacteria 

 per cubic centimeter, as follows:
