Originally published in 1920. PREFACE: Electrolytic copper refining was for so many years conducted under conditions of strict commercial secrecy that but little has been published regarding the principles of operation, as distinct from descriptions of individual plants. This littlebook comprises a series of articles, eachdealing with one of the problems of refining, which originally appeared in Chemical and Metallurgical Engineering. Whatever of value it may contain is due to the fact that it is almost entirely a record of personal experience in a field where but little literature is available.

The Nay Science offers a new perspective on the problem of scientific method in the human sciences. Taking German Indological scholarship on the Mahabharata and the Bhagavadgita as their example, Adluri and Bagchee develop a critique of the modern valorization of method over truth in the humanities. The authors show how, from its origins in eighteenth-century Neo-Protestantism onwards, the critical method was used as a way of making theological claims against rival philosophical and/or religious traditions. Via discussions of German Romanticism, the pantheism controversy, scientific positivism, and empiricism, they show how theological concerns dominated German scholarship on the Indian texts. Indology functions as a test case for wider concerns: the rise of historicism, the displacement of philosophical concerns from thinking, and the belief in the ability of a technical method to produce truth. Based on the historical evidence of the first part of the book, Adluri and Bagchee make a case in the second part for going beyond both the critical pretensions of modern academic scholarship and the objections of its post-structuralist or post-Orientalist critics. By contrasting German Indology with Plato's concern for virtue and Gandhi's focus on praxis, the authors argue for a conception of the humanities as a dialogue between the ancients and moderns and between eastern and western cultures.

For many centuries people living on volcanoes have known that the outset of seismic activity is often a forerunner of a volcanic eruption. This understand ing allowed people living close to the sites of the Mt. Nuovo 1538 eruption at Campi Flegrei, Italy, and of the Mt. Usu 1663 eruption, in Hokkaido, Japan (to quote only two examples) to flee before the eruptions started. During the second half of the 19th century seismographs were installed on some volcanoes, and the link between seismic and eruptive activity started to be assessed on a firmer scientific basis. The first systematic observations of the correlations existing between seismic activity and volcanic eruptions were probably those carried out at Mt. Vesuvius by Luigi Palmieri in 1856. Palmieri was the Director of Osservatorio Vesuviano and built an electromagnetic seismograph with the aim of "making visible the smallest ground motions by recording them on paper and indicating direction, intensity and duration". He was able to show the relationship between earthquakes and the different phases of volcanic activity. He identified the harmonic tremor which he indicated was a precursor of volcanic activity: "the characteristic feature of the ground mo tions preceding eruption is its continuity . . . (before the eruption of 1861) the electromagnetic seismograph began to show a continuous tremor". The Palmieri seismograph was also utilized in Japan until 1883, when it was replaced by the new Gray-Milne seismographs, and, later, by the Omori in struments.

Humans first used carbon as chars from firewood in ritual paintings and primitive metallurgical processes. Natural forms of carbon have been known since antiquity, yet the knowledge of the carbon element in chemistry and its technical applications on a larger scale are a relatively recent development. The industrial revolution in Europe two centuries ago led the way to the numerous applications of these graphitic forms that are still used today. Graphite and Precursors features short tutorial articles on different topics related to the science and technology of carbons intended for engineers, students of Materials Science and scientists who are seeking a fundamental understanding without "reinventing the wheel." This first volume of the World of Carbon book series focuses on graphite and its precursors, including its origin and various implications. The basic properties of hexagonal graphite are developed, and several theoretical and experimental approaches explain why this crystalline solid is fascinating in solid state physics. Also featured are the numerous applications connected to thermal, mechanical and chemical graphites, as well as their various industrial uses in polycrystalline form. Finally, carbon precursors are introduced.
