    Description / Table of Contents: Résumé Cent crânes normaux ont été étudiés sur des radiographies de profil ainsi que dix crânes pathologiques présentant des impressions basilaires chez des patients traités à l'HÔpital Kenyatta de Nairobi. La plus courte distance moyenne entre le sommet de l'odontoÏde et la ligne basale de McGregor a été de 1,2±2,28 mm au-dessous de la ligne basale (extrÊmes étendues de 6 mm au-dessous à 3 mm au-dessus de la ligne basale), chez les sujets normaux et de 9±2,7 mm (6–14 mm) au-dessus de la ligne basale chez les sujets pathologiques. L'angle basai moyen était de 113
    Notes: Summary One hundred normal lateral skull radiographs were studied and those of ten patients with basilar impression attending Kenyatta Hospital, Nairobi. The mean shortest distance of the odontoid tip to McGregor's basal line was 1.2±2.28 mm below the basal line (range 6 mm below to 3 mm above basal line), in normals and 9±2.7 mm (6–14 mm) above basal line in patients. The mean basal angle was 113

    Description / Table of Contents: Preparation and Crystal Structure of TlCu[CuO2]By reaction of Tl2O3 and Cu2O in a sealed copper-type TlCu[CuO2] was synthesized; the orthorhombically bodycentered crystallizing compound forms a new structure type, space group Imma (no. 74), with the lattice constants a = 552.5 pm, b = 605.2 pm, c = 896.4 pm. The Madelung Part of Lattice Energy, MAPLE, as well as Effective Coordination Numbers, ECoN, these via Mean Effective Ionic Radii, MEFIR, were calculated.
    Notes: Durch Umsetzung von Tl2O3 und Cu2O im verschweißten Kupfertiegel gelang die Darstellung von TlCu[CuO2]; die Verbindung kristallisiert orthorhombisch innenzentriert in einem neuen Strukturtyp, Raumgruppe Imma (Nr. 74), mit den Gitterkonstanten a = 552,5 pm, b = 605,2 pm, c = 896,4 pm. Der Madelunganteil der Gitterenergie, MAPLE, sowie Effektive Koordinationszahlen, ECoN, diese über Mittlere Effektive Ionenradien, MEFIR, wurden berechnet.

    Description / Table of Contents: Ternary Intermetallic Phases of Lithium, Transition Metals of the 4th Group and Elements of the 5th Maingroup with Statistical Metal Distribution in the „Cation“-SubstructureThe results of X-ray investigations and neutron diffraction on new and in some cases already known [1, 2] ternary intermetallic phases of Lithium with transition metals of the 4th group (b) and those of the 5th main group (X = P, As, Sb, Bi) will be reported. They crystallize in a partly „filled“ antifluorite type structure with a statistical Li/B-distribution in the tetrahedral sites. The structures are obviously stabilized by small amounts of enclosed d-elements.
    Notes: Es wird über Röntgenstrukturuntersuchungen und Neutronenbeugung an neuen und einigen schon bekannten [1, 2] ternären intermetallischen Phasen des Lithiums mit Elementen der 4. Nebengruppe (B) und Elementen der 5. Hauptgruppe (X = P, As, Sb, Bi) berichtet. Sie kristallisieren in einer teilweise „aufgefüllten“ Antifluorit-Struktur mit statistischer Li/B-Besetzung der Tetraederlücken, die offenbar durch den Einbau von geringen Mengen der Übergangsmetalle stabilisiert wird.
