The essays collected in this volume include studies of the history of the word scientist and the origin of the terms of electrochemistry as developed by Faraday, with the aid of the scholars Whewell and Whitlock Nicholl. In this bicentennial year of the birth of Faraday, the topic of his discovery of electromagnetic induction is timely, as described here in the story of the ten-year search that preceded it. Faraday enters also as the major proponent of the chemical theory of the voltaic cell, in opposition to Volta's contact theory. There is also an essay on Sir John Herschel's discovery of hypo and its application to photography. The book covers the formative period of science as a profession in England and introduces some figures of the transition to professionalism, as exemplified by Davy, Herschel, Faraday, Talbot, Whewell, and others, in terms of their work and their attitude toward it.
