1 Letter, April 19, 1803, appointing James Monroe as United States Minister Plenipotentiary to France, signed by Thomas Jefferson and James Madison.  Journal, April 27 - May 2, 1803, kept by Monroe in Paris during the Louisiana Purchase negotiations.
From the La Croix website: The flavors are derived from the natural essence oils extracted from the named fruit used in each of our LaCroix flavors. There are no sugars or artificial ingredients contained in, nor added to, these extracted flavors. There are 13 flavors of La Croix: apricot, berry, coconut, cranberry-raspberry, lemon, lime, lemon-lime, mango, orange, pamplemousse (grapefruit), passion fruit, peach-pear, and unflavored.
Otherwise, the flavoring will not have the desired flavor. The distinction in flavorings--natural versus artificial--comes from the source of these identical chemicals and may be likened to saying that an apple sold in a gas station is artificial and one sold from a fruit stand is natural.
