Preheat oven to 250 degrees. Pound the veal cutlets to an even, approximately 1/8-inch thickness, or have your butcher do this for you. In a dish, sprinkle the cutlets with lemon juice and let stand for 30 minutes. Season both sides with salt. Place the flour on a flat plate, and place the egg/water mixture in a wide, shallow bowl. Add the oil to the egg mixture and beat in with a fork. Spread the bread crumbs on a large plate. Dip the cutlets lightly into the flour, making sure to coat all surfaces, then gently shake off the excess flour. Dip the cutlets into the egg mixture, letting the excess drip away, and then dredge them in the bread crumbs. Let stand at room temperature for 20 minutes. Heat your largest, heavy skillets over medium-high heat and add the butter. When the butter is quite hot and the foam starts to subside, add the veal (cook in batches if necessary - but don't crowd them in the pan). If the butter browns too much after cooking the first batch, you may need to discard it, wipe out the pan, and add more butter for the next batch. Cook for 4 to 6 minutes on each side, until golden brown, and turn with a spatula (don't use a fork or tongs, or the breading may be pierced). When the second side is golden, the schnitzels should be cooked through. Transfer to a warm platter and keep warm in a 250 degree oven while you cook the second batch, if necessary.
