The molecular stability of metals, particularly of iron and steel
(1) ALLOW me to add some words relative to the very timely lecture on the hardening and tempering of steel, recently published by Prof. Roberts-Austen (NATURE, xli. pp. 11, 42). I desire, in the first place, to point out the bearing of the singular minimum of the viscosity of hot iron (loc. cit., p. 34) on the interpretation given of Maxwell's theory of viscosity (Phil. Mag. (5), xxvi. pp. 183, 39

Volume XIII: The tertiary insects of North America
That creatures so minute and fragile as insects, creatures which can so feebly withstand the changing seasons as to live, so to speak, but a moment, are to be found fossil, engraved, as it were, upon the rocks or embedded in their hard mass, will never cease to be a surprise to those unfamiliar with the fact. "So fragile," says Quinet, "so easy to crush, you would readily believe the insect one of

III.-The Work of Prof. Henry Carvill Lewis in Glacial Geology

He published valuable results of investigations in astronomy, mineralogy and petrology, and especially in glacial geology, the last being based on his exploration of the drift and its te

II.-Subaerial Deposits of the Arid Region of North America
A Comparison of adobe with the loess of China forms the concluding part of this paper; but as no analyses of the Chinese deposit are known to me, a few analyses of the loess of the Mississippi Valley are inserted, not with the assumption, however, that the deposits bearing the same name in these two regions are identical. A comparison of this table with the one showing the composition of adobe is

Eighth annual report of the United States Geological Survey to the Secretary of the Interior, 1886-1887: Part 1
The Geological Survey was organized, with Mr. Clarence King as Director, in March, 1879. In March, 1881, Mr. King resigned and the present Director was appointed. From its organization to the present time the Survey has steadily grown as Congress has enlarged its functions and increased its appropriations. During this time the scientific organization has gradually developed to the condition set fo
