Step into the language of the Earth. Names matter. A pocket of Victorian precision. William Humble's Dictionary of Geology and Mineralogy gathers the working vocabulary that nineteenth-century observers used to read cliffs, quarries, mines, and coastlines. Humble ranges from conchology and entomology to comparative anatomy, tying shell and bone terms to strata and time. Part geology dictionary reference, part mineralogy glossary guide, it defines the scientific lexicon dictionary of rocks, strata, ores, and processes, while reaching into botany, chemistry, zoology, and natural history fields whenever they touch the ground beneath our feet. Expect pointers through geologic formations terminology, mineral classification terms, and fossil paleontology vocabulary, made for quick consultation yet rich enough for unhurried browsing. More than a tool, this volume captures a moment when victorian era science was rapidly naming, sorting, and debating the planet's history. For geology students, it remains a geology students study aid and a field geology reference for older literature, museum labels and survey reports; casual readers can dip in for crisp definitions and the pleasure of a natural history encyclopedia in miniature. For collectors, it is a window into 19th century geology and the wider tradition where terminology was the bridge between observation and theory. Republished by Alpha Editions in a careful modern edition, this volume preserves the spirit of the original while making it effortless to enjoy today - a heritage title prepared for readers and collectors alike, and a classic geology reprint worth keeping close to the desk, bookcase, or travel bag.
