    Notes: Abstract Sixty-eight strains of capnophilic fusiform Gram-negative rods from the human oral cavity were subjected to extensive physiologic characterization, tested for susceptibility to various antibiotics, and the mol-percent guanine plus cytosine of each isolate determined. The characteristics of the isolates were compared with 10 fresh and 2 stock isolates of Fusobacterium nucleatum. The isolates clearly differed from the Fusobacterium species on the basis of molpercent guanine plus cytosine, end products, growth in a capnophilic environment and fermentation of carbohydrates. All of the gliding isolates required CO2 and formed acetate and succinate, but not H2S, indole or acetylmethylcarbinol. All fermented glucose, sucrose, maltose and mannose. The organisms may be differentiated on the basis of fermentation of additional carbohydrates, hydrolysis of polymers and reduction of nitrate. Three species are proposed: Capnocytophaga ochracea, Capnocytophaga sputigena and Capnocytophaga gingivalis. Ten isolates did not fit into the proposed species.

    A modified brice-phoenix light scattering photometer for the angular range 30° -150° (1970)

    Description / Table of Contents: Eine einfache Modifikation eines BRICE-PHOENIX-2000DM-Streulichtphotometers, das zur Messung der Streulichtintensität bei 11 verschiedenen Winkeln im Bereich von 30 bis 150° ausgerüste ist, wird beschrieben. Die Winkelauflösung ist verbesser, und Reflexionseffekte werden für Systeme mit einem Brechungsindex nahe 1,5 praktisch ausgeschieden. Mit dieser Modifikation werden gute Werte für das Depolarisierungsverhältnis für reine Flüssigkeiten gefunden. Charakteristische Daten für Polystyrol (Dow-Chemical-S 114) werden angegeben.
    Notes: A simple modification of a BRICE-PHOENIX 2000 DM light scattering photometer which provides for the measurement of the intensity of scattered light at eleven discrete angles in the range 30° -150° is described. Angular resolution is improved and reflection effects are virtually eliminated for scattering systems with a refractive index close to 1.5. Using this modification, good values for the depolarisation ratio of pure liquids are obtainable. Characterisation data for the Dow Chemical S 114 polystyrene sample are reported.
