| In der vorliegenden Arbeit wird die Geburt des Kaninchens (multipares Säugetier) und des Rindes (unipares Säugetier) beschrieben und mit der Geburt anderer Säuger verglichen. Das Verhalten der Mutter bei der Geburt hat sich nicht geändert trotz der Domestikation. Die Geburt findet meistens statt zu der Zeit, da die Tiere gewöhnlich ruhen. Dies wird von Sympathicus-Parasympathicus-Rhythmus bedingt. Die entleerten Uterusteile der Ratte und wahrscheinlich aller Multiparen ziehen sich stark zusammen, weshalb die späteren Jungen keinen längeren Weg zur Vulva zurückzulegen haben und also nicht mehr von Erstickungsgefahr bedroht werden als die ersten. Die Lage der uniparen Säuger kommst zustande infolge Formanbequemung, Gravitation und der Raumverhältnisse in der... |

| The United States occupies a rather unique position in the world wool trade - besides being one of the world's largest apparel wool producers, she also needs to supplement her requirements by sizeable imports from wool surplus countries. However, wool imports into the U.S. have a strong competitive advantage over domestic wools, not only price-wise but also on account of their uniformity and generally better preparation. For this reason the ability of the wool exporting countries to enlarge very substantially their markets in the U.S. by displacing some domestic wools is largely dependent on the American policy of sheltering and fostering the domestic wool industry. For decades, the traditional means of achieving this has been by levying specific tariff... |

| Becker (1917, 1925) considered Viola hederacea Labill., within which he placed V. sieberiana Spreng. (as V. hederacea var. Sieberi Hook, f.), to be the only member of Section Erpetion (Sweet) Becker and to belong to the ‘Antarctic Floristic Element’. V. hederacea occurs widely in temperate southern and eastern Australia (Fig. 1) where it is somewhat variable, particularly in leaf shape, and may grade rather confusedly into V. sieberiana, as on Kangaroo Island, S. Australia. Whilst examining a collection of violets on loan from the herbarium of the Papua and New Guinea Department of Forests, Lae, a specimen from Malaya was readily identified as V. hederacea: — MALAYA: Pahang Cameron Highlands, summit of Batu Brinchang, ‘exposed escarpment; stoloniferous... |
