Abstract
THIS volume, though dated 1895, was on y received a few days ago. A number of very interesting papers, some of which have been already referred to in the columns of NATURE, are contained in it, among them being the following:—“The Mexican Meteorites,” by J. R. Eastman; “Peculiarities in the Rainfall of Texas,” by A. W. Greely; “The Origin of Igneous Rocks,” by J. P. Iddings; “The Moon's Face, a study of the origin of its features,” by G. K. Gilbert; “The Texan Monsoons,” by M. W. Harrington; “The Earliest Isoclinics and Observations of Magnetic Force,” by L. A. Bauer; “Mean Density of the Earth,” by E. D. Preston. Mr. Preston's observations were made at Hawaii by two different methods, one depending upon triangulation and astronomical latitudes, and the other upon the diminution of gravity from the sea-level to the summit of a mountain, as revealed by a pendulum. The former method, carried out on Haleakala, gave for the mean density of the earth the value 5˙57; the latter method, carried out on Mauna Kea, gave 5˙13 as the density. The adopted mean is 5˙35.
