Beat 4 whole eggs lightly. Add 1 quart of milk, 1/2 cup sugar, a scant 1/4 teaspoon of salt and a level teaspoon of nutmeg. Beat well and pour into a pan, 6 x 8 inches which has been well buttered. Break about 4 slices of the bread, toasted and well buttered on top of the mixture, place the dish into a large pan of warm water and bake in a moderate oven, about 1 hour, or until a silver knife comes out clean, when tested.
