 — are strikingly similar; somehow, by some way, 

 the water supply and the sewage come into contact, 

 and if the sewage contains the discharges from many 

 typhoid-fever patients, the possibilities of epidemics 

 are enormous. 



While freezing kills a majority of typhoid bacilli, 

 enough survive to make the ice made from polluted 

 water a source of danger. 



Milk, more than any other article of food, serves as
