Home Pasteurization. It frequently happens that a 

 housewife or nurse feels obliged to treat milk in some way 

 which will remove the danger of distribution of diseases. 

 Pasteurization of milk is not an easy process because it usu-

 in the kitchen of an ordinary household can hardly use this 

 instrument intelligently. To avoid this difficulty there have 

 been devised some apparatus which make possible the 

 pasteurization of milk in small quantities by a plan so 

 simple that it can be used by any one. The method consists

 water to warm the milk and the milk to cool the water. If

 water are properly proportioned the milk will be heated to 

 the desired temperature, of about 150-180 F., and .will then

 device has been placed upon the market, shown in Fig. 24.
