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.
The sterile cheesecloth which has been boiled for fifteen minutes is now put over the nose of the pitcher, the contents of which is accurately measured into the seven clean, empty bottles, each containing three and one-half ounces. Over the top of each of the nursing bottles is placed a generous piece of waxed paper which is held down by a rubber band. Each meal for the day is now contained in a separate bottle, and all are placed in a covered pail of water containing ice, and put in the ice box.
If the prescription for the baby's food contains gruel, it is prepared in the following manner:
Suppose the baby is eight months old and the prescription called for two level tablespoons of flour and eight ounces of boiled water. The two level tablespoons of flour, whether it be wheat (ordinary bread flour), or barley flour, are put into a cup and stirred up with cold water, just as you would stir up a thickening for gravy; now measure out eight ounces of water and allow it to come to a boil in the inner pan of the double boiler, into which the thin paste is stirred until it comes to a boil. After boiling for twenty minutes, remeasure in the measuring glass and what water has been lost by evaporation must be added to complete accurately the prescription requirement of eight ounces; this is now added to the other ingredients of the prescription.
