He had already made very satisfactory progre in the study of geology and paleontology, and for the three years which followed so devoted himself to the study of physical science under his teacher, that when Prof. Aga iz undertook his voyage of exploration to Brazil, he selected H. as his first a istant. Arrived in that country, the latter was detached, with two or three a istants, to explore Southern Brazil, while Aga iz and the other members of the corps were traversing the valley of the Amazons. On his return his report of the region he had explored was so able as to give him at once a high reputation among the most advanced of physical scientists. H. was soon afterward elected profe or of geology and physical geography at Cornell University, Ithaca, N. Y. During his vacations he made other journeys to Brazil, publishing Geology and Physical Geography of Brazil. He organized the Geological Commi ion of Brazil, and died at Rio Janeiro, March 18, 1878.

( Astron . ) The full moon which occurs about the period of the autumnal equinox. It receives its name from the fact that at this time the moon rises for several nights before and after the full at nearly the same hour, thus favoring the work of the farmer during the harvest. Through certain astronomical causes, connected with the approximate coin cidence of the ecliptic, or plane of the earth's orbit, with the equator at that period, the moon's orbit becomes nearly coincident with the horizon at the close of the day, the consequence being that for several days its hour of rising is nearly the same, though its north or south position in the horizon varies considerably. This phenomenon is most striking on the Arctic circle, is noticeable in all high latitudes, and disappears at the equator.
