The late Abbé Brasseur was certainly the greatest of all modern travellers in Mexico and Central America, as far as extent of travel and long duration of stay are concerned. He knew those countries better, and had easier access to the natives, than any other similar traveller of this century. His works are therefore, actual mines of wealth so far as old documents are concerned: he has collected and brought to light more manuscripts than any other student. But his honest zeal and unrestrained enthusiasm have led him into paths on which he has wandered lamentably astray. His works are indispensable, though very little of his own conclusions can be believed.
