cold then place in refrigerator and keep cool 

 using as soon as possible. 



In pasteurizing milk for babies it is well to 

 use the nursing bottles, as this saves a great deal 

 of work and danger of contaminating the milk 

 from handling. Take as many nursing bottles 

 as there will be feedings and it is good policy 

 to have an extra one as one often gets broken, 

 and if they have no seals, plug with ordinary 

 cotton and the thermometer may be held in 

 one of them by the cotton plug. Place over 

 the fire and heat until the thermometer reg- 

 isters between 145 and 150 degrees, and then 

 remove the bottles from the fire and insert 

 the thermometer in the water which will be 

 found to be much higher in temperature than 

 the milk, and add cold water until the water 

 is from 145 to 150 degrees and then cover with 

 a clean cloth and let stand 30 minutes. Then 

 cool with water to ordinary temperature and 

 then pack broken ice around the bottles and 

 place in the refrigerator until ready for use, 

 when it may be warmed to the required tem- 

 perature. If the milk is fed in a modified form 

 this should be done before it is pastuerized. 

 If the bottles are warmed and not used, the 

 milk should be thrown away.
