    Description / Table of Contents: Zusammenfassung Verschiedene Säugetierorgane, namentlich solche mit innerer Secretion, Thyreoidea, Thymus, Nebenniere, Hoden, Eierstock, Hypophyse, Leber, Muskel usw. wurden an Kaulquappen vonRana temporaria undesculenta verfüttert. Jede Fütterung übte einen andern Einfluß auf das Wachstum und die Differenzierung der Tiere aus. Äußerst auffallend war die Wirkung der Schilddrüsennahrung. Sie verursachte eine rapide Körperdifferenzierung, die zu einer vorzeitigen Metamorphose führte, wobei aber jedes Weiterwachstum unterdrückt wurde. Die Kaulquappen begannen ihre Metamorphose wenige Tage nach der ersten Schilddrüsendosis und um Wochen früher als die Kontrolltiere. Der Einfluß der Thymusnahrung war gerade entgegengesetzt. Sie bewirkte namentlich in den ersten Tagen ein schnelles Wachstum der behandelten Tiere, schob aber die Metamorphose immer weiter hinaus oder unterdrückte sie gänzlich. Der Einfluß der übrigen Organe muß noch weiter studiert weiden. Die Thymusverfütterung ergab tief dunkel, fast schwarz gefärbte Quappen, die Nebenniere ganz lichte, albinotische Tiere, die Leber dunkle, mit einem Stich ins Grünliche.
    Notes: Summary A number of mammalian organs, especially those with an internal secretion, thyroid, thymus, adrenal, testis, ovary, hypophysis, liver, muscle etc. were given as food to tadpoles ofRana temporaria andesculenta. It was seen that each organ exerted a certain influence on growth and differentiation of the animals. Most striking was the influence of the thyroid food. It caused a precocious differentiation of the body, but suppressed further growth. The tadpoles began to metamorphose a few days after the first application of the thyroid and weeks before the control animals did so. The influence of the thymus was quite the opposite, especially during the first days of its application it caused a rapid growth of the animals, but postponed the final metamorphosis or suppressed it completely. The action of the other organs must be studied further before definite statements can be made. The thymus diet gave very dark, melanotic tadpoles, the adrenal diet extremely light albinos, the liver diet dark ones with a greenish tint.
