Household Chemistry H SEHOLD Chemistry is a science necessary in the proper manage- ment of our homes, and is therefore of particular interest to women. Its theories deal with the preparation and different ingredients of food and with those necessary implements and utensils with which our homes are supplied. In the preparation of our food, the chemistry of digestion and nutrition are of far more importance than the satisfaction of taste. The work done in the laboratory and the knowledge gained from research and experiments enable the future house-keeper to prepare food according to a balanced ration which will furnish such sustenance for the body as nature requires. Household Chemistry also teaches the composition of different utensils required about the home, and the knowledge of the effect of acids and cleansing compositions necessary for their proper care. The principal subjects of study are fuels and their management, food adulterants, balanced ration to secure a just proportion of fats, carbo- hydrates, and protein, the chemistry of digestion and nutrition, and the effects of food on the system. The pupils notice the action and ingredients of such materials as flour, baking powder, and lye. Knowledge of ventila- tion, sanitation, and the disposal of waste are important details in every household and these are among the problems which this course endeavors to simplify. Some of the important experiments which the class perform during the year are the tests of the action of acids and alkalies upon fats, starch and protein, also upon cotton and silk, and upon the materials used in the manufacturing of kitchen utensils, tests of soaps. and tests of the adulterants found in common foodstuffs. —Carol Higby.
