communal houses of the Indians at the time of the first white settlements in our country, the pueblos of New Mexico and Arizona, the structures whose ruins abound in Mexico and Central America, and the mounds of the mound-builders, illustrate a common type of house-construction and a communistic mode of living by the gens or tribe, which are not peculiar to the American aborigines, but have appeared as elements in primitive life at a stage between savagery and barbarism, among many other nations. The illustrations, drawn from and applied to all the classes of structures under review, and the historical citations, afford strong re-enforcements to the author's presentation.

Geology of the Environs of Tokio. By David Brauns, Ph. D., M. D., Professor of Geology in Tokio Daigaku. Tokio, Japan: Tokio Daigaku. 1881. Pp. 85, with Eight Plates.

This is Number IV of the "Memoirs" of the Science Department of the University of Tokio, and contains accounts of the examinations of the alluvial, diluvial, and tertiary deposits of the neighborhood of Tokio, Yokohama, and other parts of Japan, some of which present difficult problems, and descriptions of the fossils (mollusks). The conclusion is reached that the Japanese shell-layers which were examined have the greatest resemblance with the Crag, and next to it with the younger sub Apennine deposits, while the rocks resemble very closely the European Faluns. The plates, besides a sketch-map of the environs of Tokio, give representations of earth-sections and of some thirty typical fossils.

Report on the Geology and Resources of the Black Hills of Dakota. By Henry Newton, E. M., and Walter P. Jenney, E. M. Washington: Government Printing-Office. Pp. 566, with Atlas.

Professor Newton's part of this work includes the general introduction, observations on the routes to and from the Black Hills, and the account of the geological formations of the region, as observed in his survey during the summer of 1875. The author died in 1877, before completing his report, and the work of finishing it fell to Mr. C. K. Gilbert, who has performed it with fidelity to the author's intention, bearing in mind what has been learned concerning the gold of the Black Hills since the survey was made. Mr. Jenney's part of the report is his own exclusively, and includes a detailed review of the mineral resources, and the climate and general resources, of the Black Hills. Additional chapters, with plates of illustrations, are furnished: On "Paleontology," by R. P. Whitfield; "Microscopic Petrography," by John II. Caswell; "Botany," by Asa Gray; and "Astronomy" and "Barometric Hypsometry," by Horace F. Tuttle.

Measurements of the Force of Gravity at Tokio and on the Summit of Fujinoyama. By T. C. Mendenhall, Ph. D., Professor of Experimental Physics in Tokio Daigaku. Tokio, Japan: Published by Tokio Daigaku. 1881. Pp. 17.

This is Number V of the "Memoirs" of the Science Department of the University of Tokio. The experiments were conducted with a pendulum, in 1880, and produced results that seemed to show that the mountain is deficient in attraction.
