    Description: Durch Bestimmung der Foraminiferenanzahl in I g Sediment wird die biostratigraphische Untersuchungsmethode, die mittels einer qualitativen und quantitativen Erfassung der Foraminiferenfauna in den Tiefseekernen der deutschen „Meteor”-Expedition und schwedischen „Albatroß”-Expedition durchgeführt werden ist, auf ihre Richtigkeit hin geprüft. Die Untersuchung hat die Anwendbarkeit dieser stratigraphischen Methode bestätigt. Sie hat daneben wiederum gezeigt, daß die Verbreitung und Entwicklung der einzelnen Foraminiferenarten vor allem von der Temperatur des Meerwassers abhängig sind; andere Faktoren wie Phosphatgehalt des Wassers usw. scheinen in dieser Hinsicht eine mehr untergeordnete Rolle zu spielen. Unter gewissen Voraussetzungen können Tiefseekerne durch Bestimmung der Foraminiferenanzahl je 1 g Sediment in groben Zügen stratigraphisch gegliedert werden; auch kann die Individuenanzahl der einzelnen Foraminiferenarten aus der Foraminiferenanzahl in 1 g Sediment und aus der prozentualen Zusammensetzung der Gesamtfauna errechnet werden. Mit den hier gewonnenen Erkenntnissen wird versucht, die engen Bezichungen zwischen dem prozentualen Anteil der Warmwasserforaminiferen in der Gesamtfauna und dem CO2-Gehalt des Sedimentes, dieOvey im Kern 241 der schwedischen „Albatroß”-Expedition beobachtet hat, zu deuten.

    Description: Comparable values have been obtained for endogenous fecal calcium in cattle by an “isotope dilution” method and a “comparative balance” method. Both procedures involve the use of labeled calcium, but they are different in principle. The “isotope dilution” method offers advantages in being independent of the availability of the dietary calcium and of the uncertainties of balance determinations.

    Description: Endogenous fecal calcium was estimated directly in normal cattle by a method which consisted of 10 daily intravenous injections of radiocalcium, comparison of the specific activities of blood and feces taken on the 4th to 8th day post-injection, and routine determination of calcium balance. The daily endogenous fecal values for three 8-year-old dairy cows averaged 7 gm and for two yearling Hereford steers about 4 gm. The endogenous fecal calcium was not significantly changed when the dietary calcium was varied from normal to a high level. In two animals on a low calcium diet a decrease in endogenous fecal calcium was indicated.

    Description: Genaue Untersuchungen der Foraminiferenfauna in drei Sedimentkernen aus dem Tiefseeboden des äquatorialen Atlantischen Ozeans von der Schwedischen Tiefsee-Expedition an Bord des M. S. „Albatroß“ 1947/48 haben die Ergebnisse über die Schichtung der Tiefseeablagerungen an Hand des Materials von der Deutschen „Meteor“-Expedition 1925/27 nicht nur bestätigt, sondern in vielen Punkten stark erweitert. Die allgemein übliche stratigraphische Gliederung des jüngeren Quartärs kann in den Tiefseesedimenten des äquatorialen Atlantischen Ozeans durch die Schwankungen der pelagischen Foraminiferenfauna einwandfrei nachgewiesen werden. In alluvialem Material ist das Klimaoptimum (s. Kern 227 auf Abb. 3) deutlich zu erkennen, in den Ablagerungen der letzten Eiszeit (Würm) die Untergliederung in die drei Stadien (WI, II, III) und die dazwischenliegenden Interstadiale möglich. Die Grenze Würmeiszeit/Letztes Interglazial kann klar festgelegt werden (s. Abb. 3), und der 9,09 m lange Kern 227 aus dem Gebiet der Kapverdischen Inseln reicht vielleicht bis in die Sedimente aus dem zweiten Interglazial. Durch die wechselnde Zusammensetzung der pelagischen Foraminiferenfauna sind somit innerhalb der Tiefseeabsätze deutlich die Klimaschwankungen der jüngsten Vergangenheit erkennbar; d. h. die Stratigraphie der jungquartären Tiefseesedimente ist im wesentlichen durch Klimaänderungen bedingt.

    Description: The investigation of the causes of a fish kill in waters containing ferro- and ferricyanide at concentrations far under those generally accepted as non-lethal have shown these low concentrations to be lethal due to photo-decomposition and release of the cyanide ion. Experimental data place the toxic level of these compounds, under similar conditions of light intensity, at a concentration between 1 and 2 p.p.m. This level is assumed to vary slightly under natural conditions with latitude, period of the year, temperature, water turbulence, and interferences. Rapid development of toxicity has been demonstrated at a concentration of 2 p.p.m. of either potassium ferro- or ferricyanide.

    Description: in a recent publication von Brandt (1) gives a survey of all determinations of the calcium content of Baltic water hitherto published. He records in all 39 analyses made during the last century, which give us an idea of the order of magnitude of the calcium concentration; they cannot, however, serve for comparative purposes as in many cases chlorine determinations on the same water samples are lacking. Neither have we any clue for judging the accuracy of these analyses, the latest of which date from 1884. Fifty years later, in 1935, Za rin s and O z o 1 ins (8) published an extensive investi­gation of the water in the Bay of Riga and in the Baltic off the Latvian coast, their most westerly station nearly coinciding with the Finnish station F81 (Lat. 57° 22'N., Long. 19°57'E.) above the central depression of the Baltic. Their material comprised about 70 calcium analyses on water from all depths. Finally v o n B r a n d t in the above-mentioned paper publishes nearly 300 analyses of surface water collected in 1935 and 1936 during several voyages from Pillau to Helsingfors and back, and along the German coast as far as Kiel and back. The present material comprises analyses of only 48 samples of surface and bottom water collected during the summer cruise, in July 1935, of the s.s. "Nautilus" from the Gulf of Finland, the Gulf of Bothnia, and the northern half of the Baltic proper. In spite of the smaller number of samples this material is more comprehensive than the two preceding investigations in so far as it covers a greater area of the sea. I t was originally meant as a survey of the calcium content in these parts of the Baltic, but the surprisingly simple relationships between calcium content and chlorinity which it revealed, give the results far more scope than was expected.
