Rare. A pioneering work that applied for the first time stereographic, gnomonic, clinographic, and linear projection techniques to crystallographical problems. The importance of the work apparently escaped contemporary scientists, however, and only the first part was published. Neumann's ideas were later developed by William H. Miller in Cambridge in 1839, who successfully applied the technique to create his "Miller Indices," whose work was later developed by Axel Gadolin in his studies of symmetry.
