Feldspar minerals make up 60% of the crust of the Earth. They are stable in the upper mantle, and are so abundant in the crust that they form the basis of the classification of igneous rocks. At the surface, feldspars weather to form clay minerals which are the most important mineral constituent of soils. The articles in this book review the chemical reactions of feldspars over the whole sweep of pressure and temperature regimes in the outer Earth, and describe the fundamental aspects of crystal structure which underlie their properties. The book covers intracrystalline reactions, such as...

Poetry for Pleasure is an anthology representative of the great wealth of English poetry written between the sixteenth century and the present day. The book is arranged in fifteen sections, each devoted to a different theme. The first two of these comprise verse written mainly for, or about, the young or the very young. Subsequent sections deal with such varied subjects as country pleasures, love and friendship, music and dancing, the sea, time, age, sleep, and death. In fact they cover almost the whole range of human experience. Inevitably, a number of poems will be familiar to most...
