In the December Number of the GeologicalMagazine there is an abstract of a most interesting paper published in the “Jahrbuch für Mineralogie”, etc., of Leonhard and Geinitz, by C. W. C. Fuchs, entitled, “The Geological, Microscopical, and Chemical Examination of the old Sedimentary Formations in the French Pyrenees, with especial reference to the Metamorphosis of these and other old Rocks”. In this paper attention is called to the manner in which the degree of metamorphism of clay-schists and other rocks is sometimes indicated by the formation and gradual development of certain minerals, Andalusite and Chiastolite being those specially mentioned.
