In a large mixing bowl, soak the bread in the milk 2 to 3 minutes, until soggy. Using your hands, squeeze out and discard the milk. Place the bread in a large mixing bowl. Stir in the potatoes, onions, parsley, salt, pepper, nutmeg, and marjoram. Add the eggs to the mixture and mix well. Shape the mixture into about 24 (1 1/2-inch) round dumplings. Dip the dumplings into the flour to coat generously. Bring a large saucepan of lightly salted water to a boil over high heat. With a slotted spoon, gently add the dumplings to the water. Bring back to a boil. Reduce the heat to medium. Cover and cook about 15 minutes, until the dumplings expand and float to the surface. Serve with any kind of stew.
