For most of the facts in this paper I am indebted to two papers, “Le Xinantecatl ou Volcan Nevado de Toluca,” par T. Flores, and “Le Jorullo,” par E. Ordóñez, both forming part of the “Guide des Excursions du Xe Congrès Géologique International, Mexico, 1906.” An excellent general map of Mexico on which the route of the excursion can be followed is the “Carte du Mexique. Dressée an dépôt de la Guerre,” par Mr. Niox, scale = 47·34 miles to 1 inch, date 1873, price 1 franc plus postage, from II. Barrère, 21, Rue du Bac, Paris. Of railways it shows only one, but the railways up to date are shown on Rand, McNally, & Co.'s Indexed Atlas of the World, Map of Mexico, scale 72 miles to 1 inch.
