Criticizing F. Zambonini's Natrod:tvyne (1910 ; 6th List), it is pointed out that in all analyses of davyne there is an excess of sodium over potassium- if, therefore, ' natrodavyne ' is to imply the absence of potassium, then A]calida~yne would be a more suitable name. Further, as carbon dioxide may be present or absent in davyne, it is necessary to distinguish between earb~Maeyne and acctrbodavyne. Akrochordite. G. Flink, 1922. Geol. F6r. FSrh.

It occurs in cavities as highly elongated (on [001]) prisms, up to 2000 μm long and 50 μm×50μm in cross- section, associated with sanidine, astrophyllite, fluornatropyrochlore, ferrokentbrooksite, quartz and ferro- katophorite. Crystals are generally transparent and colourless, with vitreous lustre, occasionally creamy white. ∼ Fogoite-(Y) has a white streak, splintery fracture and very good {100} cleavage. Mohs hardness is 5.

The eight new mineral found in nepheline syenite pegmatite in the strongest lines of the X-ray powder diffraction pattern Sakharjok alkaline massif, Western Keivy, Kola Peninsula, [d(Å)(I)(hkl)] are: 2.991(100)(11-2), 7.238(36)(00-1), Russia. The pegmatite mainly consists of nepheline, albite, 3.061(30)(300), 4.350(23)(0-1-1), 9.145(17)(100), alkali pyroxenes, amphiboles, biotite and zeolites. 4.042(16)(11-1), 2.819(16)(3-10), 3.745(13)(2-10). The Batievaite-(Y) is a late-pegmatitic or hydrothermal mineral chemical composition determined by electron probe micro- associated with meliphanite, fluorite, calcite, zircon, analysis (EPMA) is (wt.%): Nb2 O 5 2.25, TiO2 britholite-group minerals, leucophanite, gadolinite-subgroup 8.01, ZrO2 2.72, SiO2 29.96, Al2O3 0.56, Fe2O3 0.43, Y2O3 minerals, titanite, smectites, pyrochlore-group minerals, 11.45, La2O3 0.22, Ce2O3 0.33, Nd2O3 0.02, Gd2O3 zirkelite, cerianite-(Ce), rutile, behoite, ilmenite, apatite- 0.07, Dy2O3 0.47, Er2O3 1.07, Tm2O3 0.25, Yb2O3 2.81, group minerals, mimetite, molybdenite, and nickeline.
