Abdruck aus den Berichten der Math.-Phys. Klasse der Königlich Sächsischen Gesellschaft der Wissenschaften zu Leipzig, 53.Bd. - Leipzig 1911, 8°, pp.249-257, pp.402-406, Fig., 2 orig. Broschur; in zubindbarer marmor. Schutzmappe. Umfangreiches Konvolut von bedeutenden Arbeiten des Begründers der modernen polarisationsmikroskopischen Untersuchungsmethoden. "Neben die Auswertung der Befunde tritt in der zweiten Hälfte des vorigen (19.Jh.) Jahrhunderts die Frage nach der Ursache der Doppelbrechung tierischer und pflanzlicher Strukturen. Zwar kündet optische Anisotropie stets die Anwesenheit eines sub- oder amikroskopischen anisometrischen Feinbaues an; aber wie dieser beschaffen, darüber gingen die Meinungen anfangs sehr auseinander: EHRENBERG (1849), BRÜCKE (1858: Disdiaklastenhypothese), Hugo von MOHL (1859) und insbesondere C.v.NAEGELI (1859; 1862; 1879: Micellarhypothese) sprachen sich für Kristallinität aus, CH.ROUGET (1862) und W.HOFMEISTER (1867) für die Wirksamkeit feinster lichtbeugender Lamellierungen oder Streifungen (Depolarisationshypothese); v. EBNER (1882) aber nahm an, die an sich isotropen Teilchen der Gewebe erhielten durch Spannungen während des Wachstums nach verschiedenen Richtungen unterschiedliche Abstände (Spannungshypothese). Die durch scheinbar widersprechende Beobachtungen sehr verwickelte Sachlage klärten in den Jahren 1910 bis 1919 H.AMBRONNs Untersuchungen an Gallerten organismischer Herkunft, wie Gelatine und Celloidin. Er gelangte nicht nur zu einer Trennung von Orientierungsdoppelbrechung und photoelastischem Effekt, die bis dahin bei solchen Objekten vielfach noch zusammengeworfen wurden, sondern er konnte bei der Orientierungsdoppelbrechung zwei Anteile von ganz verschiedener Art unterscheiden, die Texturdoppelbrechung, die durch die Anisometrie eines submikroskopischen Feinbaues nach Art eines WIENERschen Mischköpers hervorgerufen wird, und die Eigendoppelbrechung, die auf amikroskopischem Feinbau der Texturelemente selbst zu beziehen ist, der bald darauf durch das Röntgen-Faserdiagramm als raumgittermäßige Ordnung gesichert wurde. Auf dieser Grundlage und unter Beachtung der neueren Einsichten in die Stereochemie der Baustoffe ließ sich die Polarisationsoptik von Zell- und Gewebestrukturen als hydrogele und lipoide Schichtsysteme befriedigend deuten und zugleich für die Analyse des Feinbaues verwenden." W.J.Schmidt Diese kleine Sammlung enthält folgende weitere Schriften von Hermann Ambronn: 1.: Ueber Umkristallisation und Gel-Bildung beim Erhärten des Zementes (1909, 7 pp.). 2.: Über die Dispersion der Doppelbrechung in den Mischkristallen von Strontium- und Bleidihionat (1913, 11 pp., farb. Tafl.). 3.: Ein Demonstrationsversuch zur Abbeschen Theorie der mikroskopischen Wahrnehmung (1913, 11 pp.). 4.: Die Untersuchung der Nitrozellulosen im Polarisationsmikroskop (1913, 8 pp.). 5.: Über Stäbchendoppelbrechung im Zelloidin und in der Gelatine (1915, 16 pp.). 6.+7.: Ueber das Zusammenwirken von Stäbchendoppelbrechung und Eigendoppelbrechung. I+II (1916, 8 pp., 10 pp.). 8.: Über die akzidentelle Doppelbrechung im Zelloidin und in der Zellulose (1919, 22 pp.). 9.: Das Polarisationsmikroskop. Seine Anwendung in der Kolloidforschung und in der Färberei. Von Hermann Ambronn & Albert Frey (1926, X, 194 pp., 48 Fig., 1 farb. Taf.).

Erstdruck! Hermann Ambronn (1856-1927) studierte in Heidelberg, Wien und Berlin bei S. Schwendener, promovierte 1880 mit einer Arbeit ber die Rotalgen, wurde 1881 Assistent am botanischen Institut und 1887 Kustos am Universitõts-Herbarium, 1889 au?erordentlicher Professor in Leipzig, 1899 in Jena (Lehrstuhl f r wissenschaftliche Mikroskopie). Hier war er bis 1907 wissenschaftlicher Mitarbeiter der optischen Werkstõtten von G. Zei? und leitete das 1902 auf E. Abbes Veranlassung mit Mitteln der Carl Zei?-Stiftung gegr ndete Institut f r wissenschaftliche Mikroskopie. - Ambronn studierte vor allem die submikroskopische Struktur der doppelbrechenden Substanzen pflanzlicher und tierischer Herkunft. Er ver÷ffentlichte Arbeiten aus dem Gebiete der Botanik, der Kolloidchemie - grundlegend ist hier seine Entdeckung der Stõbchendoppelbrechung in vielen Kolloiden, die spõter durch die Entdeckung der R÷ntgendiagramme bestõtigt wurde - und der Mineralogie."
