The process is exactly the same as the partially peptonized milk, except that it is continued for two hours, which is required for the conversion of all the proteins into peptones. For older children the bitter taste may be covered by lemon-juice and cane-sugar, one even teaspoonful of cane-sugar and two teaspoonfuls of lemon-juice being added to ℥iv of milk. BUTTERMILK. To 1 quart of fat-free milk add 8 ounces of sterile water. Crush tablet of lactic acid bacilli into the mixture; allow to stand for twenty-four hours at room temperature, then place on ice. DIRECTIONS FOR MAKING BUTTERMILK FROM LACTONE TABLETS. Fresh skimmed milk, 1 quart; Hot water, 1½ to 2 cupsful; Salt, ½ teaspoonful; Lactone tablet, 1.

BEEF JUICE. I. Cut meat into one-inch cubes; broil slightly and press out juice with meat-press or lemon-squeezer. One pound of meat will make 2 or 3 ounces of juice. Serve warm or cold with a little salt. Do not heat enough to coagulate albumen in juice. II. Cold method: Finely chopped beef, 1 lb.; Water, ℥viij. Put in covered jar; allow to stand on ice from six to twelve hours; then squeeze out by twisting in coarse muslin. Season with salt and serve as above. This contains a smaller amount of extractives. It may be served with sherry wine or celery salt. If added to milk in the proportion of 2 or 3 tablespoonfuls to the feeding, the taste will not be noticed. The milk should not be heated over 100° F., as the albumen will coagulate. No. I. contains twice the amount of extractives as No. II. If the stronger juice is desired, No. II. may be made by adding only ℥iv of water instead of ℥viij. VEGETABLE SOUP FOR BABIES. 1 handful of spinach; 1 beet; 2 carrots.
