Slice French bread into 20 slices, 1-inch each. (Use any extra bread for garlic toast or bread crumbs). Arrange slices in a generously buttered 9 by 13-inch flat baking dish in 2 rows, overlapping the slices.
In a large bowl, combine the eggs, half-and-half, milk, sugar, vanilla, cinnamon, nutmeg and salt and beat with a rotary beater or whisk until blended but not too bubbly.
Pour mixture over the bread slices, making sure all are covered evenly with the milk-egg mixture. Spoon some of the mixture in between the slices.
Cover with foil and refrigerate overnight.
