Convalescents can sometimes relish and digest these sooner than any other solid food. Place a dozen fresh oysters in the shell upon a moderately strong fire, and allow them to remain there until their shells open a little. Then take them from the fire, open them at once, retaining the juice if possible, and serve them hot, with perhaps a little black pepper, and salt if needed. If the " hard part" is at all tough, it had better not be eaten.
