Scarce. This major topographical work covers the important mining region of the Siebenburgen located in present day Romania. In the first part of the forward, Ackner outlines his goals and reasons for writing this book. He notes that no previous work had sufficiently described the mineralogical wonders of the area. He qualifies this view by providing a list of earlier titles, and outlining the comprehensive treatment he plans. Ackner began work in 1844, which is the first date of the forward. In the "Nachschrift" that immediately follows, he recounts how the first Heft of this book was published in 1847, and that it was only after eight years of thorough research that the volume was completed in 1855. The text is a descriptive mineralogy in the arrangement of C.S. Weiss' system of classification. Each species found in the region is provided a description giving copious notes about localities, associations, crystallography, and chemistry.
