this relic of semicivilized antiquity. He was greatly interested in the history of the earliest discoveries of the Spanish and Portuguese ex- plorers and navigators in America. His most extensive paper, " The Portuguese in the Track of Columbus," illustrated by many maps, was published in the Bulletin of the American Geographical Society, New York. His remarks on the travels of Pinzon, who first saw the mouth of Amazon river, were recorded and reviewed in the American Anti- quarian of Chicago. One of his last publications belonged to this class, and is entitled " Pinzon-Solis, 1508," published in the Zeitschrift der Gesellschaft fur Erdkunde, Berlin, 1898. His last work, now being published in the journal of American Folk-Lore, is on the Trique In- dians of the state of Oaxaca, which he read at the meeting of the Folk- Lore Society in Columbia University in December last.

Dr Valentini left a great number of manuscripts and notes, several of which are practically ready for publication. His most important contribution was an historical work on Costa Rica, bearing the title Castilla de Oro. This treats of the early history of Costa Rica, and it is hoped that it will eventually be published by the Costa Rica govern- ment. During the last three years he was engaged in making exhaus- tive studies of the migrations of the early Mexican people, finding analogies with their culture in Persia and Tibet.
