Preheat oven to 350 degrees. Butter and flour a 9 by 13-inch glass casserole dish. Pour melted butter into the dish. In a saucepan, slowly cook the peaches with 1/2 cup sugar until soft. Add cinnamon and nutmeg to taste. Combine flour with remaining sugar, baking powder, and salt. Whisk in milk and pour mixture into pan over butter. Gently pour cooked peaches evenly over batter. Cook for 45 minutes or until golden brown.
