Very scarce. Published anonymously, but attributed to Volkelt. In this introduction to mineralogy for the beginner, the author has relied upon the previous works of Wallerius, Henckel, Cartheuser, Woltersdorff and others for his information. He begins the text with discussions of earths, salts, hard-earths, stones including precious, common and figured, and metals. There is a short description of the merits and how to form a mineral cabinet for the reader. Then Volkelt continues with descriptions of the chemical nature and makeup of minerals. All the discussions are highly abbreviated due to the modest length of the book.
