Note IX-26 — Chapter IX · ANTIQUITIES OF THE CENTRAL PLATEAUX.

'On voit encore beaucoup de restes de cette grande muraille, conservés avec d'autant plus de soin qu'il s'y trouve des quartiers de roc de plus de vingt pieds d'épaisseur.' Brasseur de Bourbourg, Hist. Nat. Civ., tom. iv., p. 135; Lorenzana, in Cortés, Hist. N. España, pp. vi.-vii.; Bradford's Amer. Antiq., pp. 104-5. Additional references to slight notices of ruins and relics in the region about Tlascala, containing no available information, are as follows: Camargo, in Nouvelles Annales des Voy., 1843, tom. xcviii., pp. 135-7; Helps' Span. Conq., vol. ii., p. 423; Mühlenpfordt, Mejico, tom. ii., pp. 238, 240. The Historical Magazine, vol. x., pp. 308-10, has an extract from a Mexican newspaper, in which reference is made to an official report of a prefect of the department, announcing the discovery of two magnificent cities. They were probably identical with some of the ruins already described in Vera Cruz.
