Although the reaction takes place quickly, by making preparations as advised all of the pails can be " set off " promptly by one person, since there is nothing to do but pour the formaldehyde solution over the permanganate.

TABLE OF 100-CALORIE PORTIONS OF FOODS

Explanation Of Table. — The first column of figures in the table gives the number of i00-Calorie portions in one pound of the food as purchased. The next four columns show the weight of food which yields 100 Calories, i.e. the weight of the i00Calorie portion, both in ounces and in grams, and both for the material as purchased and for the edible portion. Next follow columns showing the amount of protein first in Calories and then in grams, which the i00-Calorie portion of food contains. The protein content as thus expressed often gives a truer impression of the food as a source of protein than does the percentage by weight of protein which the food material contains.
