Beef Tea, or Essence of Beef.
Cut, say, a pound of perfectly lean beef into small pieces, put them into a wide-mouthed bottle (a pickle-bottle answers the purpose), cork it tightly, and place it in a pot of cold water in which there is a saucer at the bottom. Heat it gradually, then let it boil slowly for two or three hours, when all the juice will be drawn out of the meat.
Now pour off the juice, season it with salt carefully, as it requires very little. When it is cold, skim off all the globules of fat.
This is an invaluable aliment for invalids who are very ill, or for weak infants, when they need much nourishment in small compass. This beef tea can then be given by the tea-spoonful at regular intervals, administering it as medicine.
