Page liii - This will be the fame of Watt with future generations ; and it is sufficient for his race and his country. But to those to whom he more immediately belonged, who lived in his society, and enjoyed his conversation, it is not perhaps the character in which he will be most frequently recalled — most deeply lamented — or even most highly admired.
Page 178 - The state of pronounced alteration is the disintegration of the firm rock into a mass of hard, angular fragments, varying in size from that of a bean to that of a human fist, which apparently do not readily disintegrate on exposure to the weather. The second stage of alteration, due to further weathering, yields a compact mass, the so-called "green ground," showing various shades of light olive green, and often bluish in tint when moist, but becoming yellowish on drying.

Page 225 - MALLEABLE PIG IRON, an American trade name for the pig iron suitable for converting into malleable castings through the process of melting, treating when molten, casting in a brittle state, and then making malleable without remelting. The term should be used with care to avoid confusion. This material is also called in trade in America
Page 225 - Steel. — Iron which is malleable at least in some one range of temperature, and in addition is either (a) cast into an initially malleable mass, or (6) is capable of hardening greatly by sudden cooling, or (c) is both so cast and so capable of hardening.
