    Description / Table of Contents: Zusammenfassung.  Die Analyse der im Titel genannten Ablagerungen ergab Calcium, Carbonat und Phosphat neben geringen Mengen anderer anorganischer Ionen. Außerdem wurden gesättigte, ungesättigte und ungeradzahlige Fettsäuren neben extrahierbaren Proteinen von ca. 29, 45 und 66 kD nachgewiesen.
    Notes: Summary.  Analysis of the lumps mentioned in the title revealed calcium, phosphate, and carbonate besides minor quantities of other inorganic ions. Moreover, saturated, unsaturated, and odd numbered fatty acids as well as extractable proteins of about 29, 45, and 66 kD were identified.

    Description / Table of Contents: Zusammenfassung.  Mono-O,O- und Mono-S,S-ketale von 1,3-Diphenylpropan-1,3-dionen liefern mit Hydroxylaminhydrochlorid bzw. O-Methylhydroxylaminhydrochlorid (E/Z)-Gemische der Oxime bzw. der O-Methyloxime, die sich nur schwer oder überhaupt nicht trennen lassen. Andererseits sind isomerenreine Oxime bzw. O-Methyloxime durch Umsetzung von 2-lithiierten 1,3-Dithianen mit α-Halogenoximen und ihren O-Methylethern oder durch Reaktion von lithiierten Oximethern mit Dithieniumsalzen zugänglich. Reduktion, Acetylierung, Ketalspaltung und Oximbildung führen dann zu 3-Aminooximen. Diese Verbindungen sind Vorstufen für 1,3-Diphenylpropan-1,3-diamine.
    Notes: Summary.  Mono-O,O- and mono-S,S-ketals of 1,3-diphenylpropane-1,3-diones react with hydroxylamine hydrochloride and O-methylhydroxylamine hydrochloride affording mixtures of (E/Z) isomers which are hard to separate or are even unseparable. Isomerically pure oximes and O-methyloximes, however, are obtained either from 2-lithiated 1,3-dithianes and α-halogeno-oximes and α-halogeno-oxime ethers, resp., or from lithiated oxime ethers and dithienium salts. Reduction, acetylation, hydrolysis of the ketal increment, and oximation afford 3-amino-oximes which are precursors of 1,3-diphenylpropane-1,3-diamines.

    Notes: Summary Mammals and birds have independently developed different populations of sensory cells grouped across the width of their auditory papillae. Although in mammals there is clear evidence for disparate functions for the two hair-cell populations, the different anatomical pattern in birds has made comparisons difficult. In two species of birds, we have used single-fibre staining techniques to trace physiologically-characterized primary auditory nerve fibres to their peripheral synapses. As in mammals, acoustically-active afferent fibres of these birds innervate exclusively the neurally-lying group of hair cells in a 1∶1 relationship, suggesting important parallels in the functional organization of the auditory papillae in these two vertebrate classes. In addition, we found a strong trend of the threshold to acoustic stimuli at the characteristic frequency across the width of the avian papilla.
