Very scarce. This is a catalog of the ancient artifacts, fossils and minerals contained in the immense Egyptian collection of Cardinal Borgia, then housed in Rome and Velletri. The collections were founded in the early part of the 17th century by Cardinal Scipio Borgese [1734-1782], nephew of Pope Pius V. Using the classification methodology of Werner and Emmerling, Wad lists both natural specimens and gives accounts of ancient jewelry and precious and semi-precious stones cut from the material. The most valuable parts of the collection were confiscated by Napoleon, and moved to Paris, for which 15 million francs compensation was promised. However, it was never paid in full. A new collection was formed on the remnants of the original between 1820 and 1850 by the Princes Borghese. These collections are today in the Museo Borgiano, Rome, and in the National Museum, Naples.

Rare. An attempt to arrange systematically the mineralogical nomenclature of Wernerian theorists into a series of equivalents tables in the Latin, Danish, and German languages. The text consists of sections providing information about the terminology used for the external characters of minerals, crystal forms, physical and chemical properties.
