Y., 1842; London, 1843; again, N. Y., 1856, 1858). It was in the early days of the Daguerrean process, and Catherwood took with him a camera, from which his excellent drawings derive some of their fidelity. They appeared in his own _Views of Ancient Monuments in Central America_ (N. Y., 1844), on a larger scale than in Stephens’s smaller pages. [Illustration: WALDECK. After an etching published in the _Annuaire de la Soc. Amer. de France_. Cf. _Amer. Antiq. Soc. Proc._, October, 1875.] Stephens’s earlier book had had an almost immediate success. The reviewers were unanimous in commendation, as they might well be.[1036] It has been asserted that it was in order to avail of this new interest that a resident of New Orleans, Mr. B. M. Norman, hastened to Yucatan, while Stephens was there a second time, and during the winter of 1841-42 made the trip among the ruins, which is recorded in his _Rambles in Yucatan, or Notes of Travel through the peninsula, including a Visit to the Remarkable Ruins of Chi-chen, Kabah Zayi, and Uxmal_ (New York, 1843).[1037] The Daguerrean camera was also used by the Baron von Friederichsthal in his studies at Uxmal and Chichen-Itza, and his exploration seems to have taken place between the two visits of Stephens, as Bancroft determines from a letter (April 21, 1841) written after the baron had started on his return voyage to Europe.[1038] In Paris, in October, 1841, under the introduction of Humboldt, Friederichsthal addressed the Academy, and his paper was printed in the _Nouvelles Annales des Voyages_ (xcii. 297) as “Les Monuments de l’Yucatan.”[1039] The camera was not, however, brought to the aid of the student with the most satisfactory results till Charnay, in 1858, visited Izamal, Chichen-Itza, and Uxmal. He gave a foretaste of his results in the _Bulletin de la Soc. de Géog_. (1861, vol. ii. 364), and in 1863 gave not very extended descriptions, relying mostly on his _Atlas_ of photographs in his _Cités et Ruines Américaines_, a part of which volume consists of the architectural speculations of Viollet le Duc. Beside the farther studies of Charnay in his _Anciens Villes du Nouveau Monde_ (Paris, 1885), there have been recent explorations in Yucatan by Dr. Augustus Le Plongeon and his wife, mainly at Chichen-Itza, in which for a while he had the aid and countenance of Mr. Stephen Salisbury, Jr.,[1040] of Worcester, Mass. Le Plongeon’s results are decidedly novel and helpful, but they were expressed with more license of explication than satisfied the committee of that society, when his papers were referred to them for publication, and than has proved acceptable to other examiners.[1041] Nearly all other descriptions of the Yucatan ruins have been derived substantially from these chief authorities.[1042] [Illustration: DÉSIRÉ CHARNAY.
