BECHER (Johann Joachim).
Physica Subterranea profundam Subterraneorum Genesim e principiis hucusque ignotis ostendens, opus sine pari. Specimen Becherianum, Fundamentorum, Documentorum, Experimentorum subjunxit Georg. Ernestus Stahl
Lipsiae, Ex Officina Weidmanniana, 1738. 4to. 7 leaves. 504 pages. 9 leaves. 2 leaves. 161 pages. 4 leaves. Marbled calf, gilt spine with raised bands (contemporary binding). This collection of works on chemistry, alchemy and mineralogy entitled "Physica Subterranea" is certainly the best work by German chemist Johan Joachim Becher (1635-1682). This edition, the best, is to be credited to the German physician and chemist Georg Ernst Stahl: it includes both a preface and a treatise by Stahl himself, entitled "Specimen Beccherianum". This volume consists of 5 parts, each with a specific title. The first four are entitled "Physica Subterranea", "Experimentum Chimicum Novum quo Artificialis and instantanea Metallorum Generatio and Transmutatio ad oculum demonstratur", "In Physicam Subterraneam demontratio philosophica seu Theses Chimica" and "Experimentum novum ac curiosum de Minera Arenaria Perpetua" . The fifth part, with separate pagination, is dedicated to Stahl's treatise, the full title of which is "Specimen Beccherianum . quibus Principia Mixionis Subterranea and Instrumenta Naturalia atque Artificialia". Becher, one of the best German chemists of the 17th century, studied chemistry, alchemy, and mineralogy. He developed a theory of combustion which served as a basis for his disciple Stahl's famous phlogiston theory. Beautifully-etched engraved frontispiece. Minor flaws to binding, but good copy overall. Fergusson, I, 88-89. Hoeffer, II, 215-216. [Attributes: Hard Cover]
