Rare. A description of the mineralized forms of the silver chloride and bromide mineral species found in the German mines. Because of their particular crystallization characteristics, they resembled the horns of animals when encountered in the mines, hence the nickname given by the miners "horn-silver". The first portion of the text recounts the history of hornerzes, including its first discovery, the origin of the name, its occurance, and the probable origin of the ore in the mines. The second portion provides a natural history of the species including external characteristics and its forms and crystal structure. The plate shows 6 figures of various crystallized specimens.
