In this way thereis a gradual displacement of the warm water by this coldwater, until the water is all cold. After the bottles are sufficiently cooled, they shouldbe removed to the refrigerator. The rapid cooling of thebottles is as important as the pasteurization by the milk should be kept no longer than twenty- PASTEURIZED MILK. 181 four hours. We can pasteurize in other ways with anyordinary sterilizing apparatus. Thus, the Arnold steam-sterilizer (see Fig. 23), leaving the hood off, can be util-ized for this purpose. To be sure that we are attainingthe correct temperature, we can insert a special ther-mometer, which is made for sterilizing bottles. It can beprocured from any chemist or from the Arnold SterilizerCompany. To pasteurize with any ordinary sterilizer, set a ther-mometer into one bottle and put the sterilizer on a briskfire until the thermometer reaches 170° F. Then remove. Fig. 27. to the back of the stove, take out the thermometer, stopperthe bottle that contained the same, and cover with a hoodor the lid of the tin pail for fifteen minutes. Then fillthe inside of the pail with hot water around the bottlesas near to the top as possible, remove to the sink, and allowa stream of cold water from the faucet to displace thewarm water. A point worth noting is that the cold watermust not be allowed to splash on the hot bottles, other-wise it will crack them. It usually takes about ten min-utes to gradually displace the hot water in the tin pail orkettle used as a sterilizing chamber, after which the bottlesof milk are to be placed in a refrigerator and left there 182 INFANT-FEEDING. until ready for use. It is understood that each bottle isto be warmed to about a body-temperature of 98° to 100°immediately before fe
