From Table No. 89 it appears that out of 202 samples taken directly 

 from farmers' cans, 18 contained milk testing from one million to five 

 million bacteria; 22 from five hundred thousand to a million, and 47 

 from two to five hundred thousand. When one considers the nearby 

 source of supply for the City of Rochester, it is not unreasonable to ex- 

 pect milk to arrive in the city containing not more than two hundred 

 thousand bacteria, if sanitary precautions have been carried out. Con- 

 sequently, at least 87 of the samples of milk out of the 202 contained 

 numbers of bacteria so large that they plainly indicated lack of proper 

 sanitary precautions.
