In a large preserving kettle place all the utensils needed in the preparation of the food--pitcher, spoon, fork, measuring glass, bottles, nipples, cheesecloth for straining, agate cup, wire strainer, in fact everything that is to be used in the preparation of the food. Now fill the kettle with cold water and place over the gas and allow to boil for fifteen minutes. On a well-scrubbed worktable place a clean dish towel, and on this put the utensils and the bottles right side up. The nipples on being taken out of the boiling water will dry of themselves; they should be placed in a glass-covered jar until they are needed for each individual feeding, the nipples not being placed on the bottles as they go to the ice box. Having been given your formula by your physician, proceed in the following way. Suppose we were preparing the food for a normal two-months old baby that weighed ten pounds, with the prescription as follows: BABY SMITH. R_{x} Whole Milk ounces 11 Cane Sugar level tablespoons 2 Boiled Water ounces 121/2 Lime Water ounces 1 Amount at Each Feeding ounces 31/2 Number of Bottles 7 Interval Between Feedings hours 3 DETAILS OF PREPARATION Two level tablespoons of cane sugar are placed in the agate cup and dissolved in a small amount of boiling water. The solution should be perfectly clear, and if it does not clear up put it over the heat for a few moments. This is now turned into the eight-ounce measuring glass which is then filled with boiling water and emptied into the two-quart pitcher. We need four and one-half more ounces of boiling water to complete the prescription requirement of twelve and one-half ounces. The bottle of milk, if properly certified, need not be pasteurized; but if it is not, it should have been previously pasteurized while the utensils were boiling according to the suggestions found in the chapter on "milk sanitation." The top of the milk bottle should be thoroughly rinsed and wiped dry, and after a thorough shaking of the milk, the cover is removed with the sterile fork and eleven ounces are measured out by measuring glass and poured into the pitcher. All is now stirred together with an ounce of lime water, which should never look murky, but should be as clear as the clearest water and should always be kept in the ice box when not in use.
