sculpture differing essentially from all specimens known to exist of American aboriginal art. Dr. Le Plongeon is an enthusiast in his chosen career, that of an archæologist and an explorer. Without the energy and strong imagination he has displayed, he would not, alone and unassisted, have braved the dangers and privations of a prolonged residence in the wilds, surrounded by perils from exposure to a tropical climate, and from the dangerous proximity of hostile savages. All that can be learned of the life of this investigator is, that he was educated at Paris, and in 1849 went to California as an engineer, and there laid out the town of Marysville. Then he visited Peru, and travelled with Mr. Squire and took photographs of ruins. He came to New York in 1871, with three valuable paintings, which he had procured in Peru, two of them said to be Murillo’s, and the other the work of Juan del Castillo, Murillo’s first master. A long account of these pictures appears in the “New York Evening Mail” of March 2, 1871. He took them to England in the same year, and is said to have sold them to the British Museum. Since his residence in Yucatan, both the Doctor and Mrs. Le Plongeon have been engaged in archæological studies and explorations among the ruins of Chichen-Itza, Uxmal, and Aké, and they have also visited other ruins in the eastern part of Yucatan, together with those of the once famous islands of Cozumel and Mugeres, and have there pursued the same system of investigation. They are at present at Belize, British Honduras, where this explorer is awaiting a reply to his appeal, as an American citizen, to our Minister at Mexico for redress for the loss of the statue which he had discovered, and which has been removed by the government to Mexico, without his knowledge or consent, to be there placed in the National Museum. The writer is in possession of many of Dr. Le Plongeon’s letters and communications, all of them in English, and very interesting to antiquarian students. It is regretted that the shortness of time since receiving the more important of these documents will prevent doing justice to the very elaborate and extended material which is at hand; but it is with the hope that interest and coöperation may be awakened in Dr. Le Plongeon and his labors, that this crude and unsatisfactory statement, and imperfect and hasty reference to his letters, is presented.
