    Description / Table of Contents: Zusammenfassung Neue Messungen der Löslichkeiten von K-Acetat und K-Benzoat in wäßrigen Lösungen von 1,4-Dioxan bzw. THF wurden durchgeführt. Es wird eine quasi-thermodynamische Behandlung der Daten mit einer Kombination von chemischer Thermodynamik und einer uneingeschränktenDebye-Hückel-Theorie der Elektrolyte in Lösung angewandt; diese theoretische Beschreibung liefert eine Beziehung zwischen der Löslichkeit eines Salzes und der Lösungs-mittelpolarität.
    Notes: Abstract New measurements upon the respective solubilities of potassium acetate and benzoate at 25 °C in aqueous 1,4-dioxane and in aqueous tetrahydrofuran are reported, together with a quasi-thermodynamic development, from the union of chemical thermodynamics with the unrestricted result of theDebye-Hückel theory of electrolytes in solution, of a general theoretical function which in principle provides a summary descriptive expression of the relationship between the solibilities of any salt at any natural limiting concentrations and the polarities of its solvents.

    Notes: Summary The projection of peripheral sensory and motor nerves was investigated in the pigeon (Columba livia) by means of retrogradely transported fluorescent dyes. Two combinations of fluorescent tracers were used that could be identified within the same cell when excited by light of 405 nm: 1) Propidium iodide and Bisbenzimide, which label the cytoplasm orange and the nucleus blue, respectively; 2) Fast Blue, which labels the cytoplasm blue, and Nuclear Yellow, which labels the nucleus (especially the nucleolar ring) yellow. The presence of the tracers in a given cell was confirmed microspectrophotometrically. Following injection of the tracers into peripheral nerves, labelled sensory neurones were seen in the dorsal root ganglia and motoneurones of the spinal cord. The peroneal and tibial nerves projected to L2–L5 and L2–L7, respectively, whereas the median and ulnar nerves projected to C12-Th2 and C13-Th1. Double-labelled sensory neurones were observed when both peroneal and tibial, or median and ulnar nerves were injected with different tracers. This indicates that some sensory neurones possess peripheral processes that dichotomize to pass down two different peripheral nerves. Double labelling was never seen in motoneurones, or in sensory neurones after tracer injection into the sciatic and femoral nerves.
