In a large bowl, pour boiling water over oatmeal and margarine. Let stand 10 minutes. Stir in milk, egg, sugar, bouillon and cornmeal. Add flour, one cup at a time, mixing well after each addition. Knead in the final half cup or more to make a stiff dough. Pat or roll to 1/2 inch thickness. Cut into bone shapes and place on a greased baking sheet. Bake in a 325û oven for 50 minutes.
