Type material of 41 Australian Bothriembryon taxa present in Australian museums is critically listed, indicating systematic issues that need to be resolved in further studies. Information on additional type material of 22 taxa in non-Australian museums is compiled. The seven fossil taxa known so far are included in this catalogue. Based on the current systematic position, 38 species are treated...

was suggested by Rotter (1937). He observed that when 0.01 c.cm. of a N/400 solution of the dye 2 : 6-dichlorophenol indophenol was injected intradermally, the colour of the dye disappeared gradually. When methyl blue was similarly injected, its colour remained unchanged, which showed that the decolorization of dichlorophenol indophenol was not due to resorption but to reduction. Rotter (1938) ...

It has been shown by Schumann (1940), Verzar & Montigel (1941, 1942, 1943a, 1943b) and by Kutscher & Wust (1941, 1942) that, after adrenalectomy, phosphorylation of glycogen by muscle and liver (Doetsch, 1945) is decreased. Since some authors were not able to confirm this observation (Riesser, 1943-5; Smits, 1943-5; Helve, 1940) the experiments were repeated in this laboratory by Staehelin & Vo...

Between 1776 and 1920, the US Congress designed more than 200 distinct securities and stated the maximum amount of each that the Treasury could sell. Between 1917 and 1939, Congress gradually delegated all decisions about designing US debt instruments to the Treasury. In 1939, Congress began imposing a limit on the par value of total federal debt outstanding. By summing Congressional borrowing ...

A new species of the genus Eremosaprinus Ross, 1939, E. warneri, is described from southeastern Arizona, USA, and incorporated into the identification key for the genus. Description of the new species is supplemented with SEM micrographs and drawings of sensory structures of the antenna and male genitalia. New distribution data on four species, E. distinctus Lundgren, 1992, E. hubbardi (Wenzel,...

Edmund Beecher Wilson [4] contributed to cell biology, the study of cells, in the US during the end of the nineteenth and the beginning of the twentieth centuries. His three editions of The Cell in Development and Inheritance [5] (or Heredity [6]) in 1896, 1900, and 1925 introduced generations of students to cell biology. In The Cell, Wilson described the evidence and theories of his time about...

Walter Jakob Gehring [3] discovered the homeobox [4], a DNA segment found in a specific cluster of genes [5] that determine the body plan of animals, plants, and fungi. Gehring identified the homeobox [4] in 1983, with the help of colleagues while isolating the Antennapedia (Antp) gene in fruit flies (Drosophila [6]) at the University of Basel [7] in Basel, Switzerland. Hox genes [8], a family ...

This essay briefly examines the British military and their decline as a world military leader between 1919-1939. During this period one could argue that naiveté clouded the lens through which they viewed military power in general in relation to other nations causing miscalculations in particular with regard to strategic policy considerations. We can contrast their lens then with our lens today ...

Stephen F. Heinemann Starting in the late 1960s and early 1970s, a group of aspiring young scientists gathered at the Salk Institute for Biological Studies in La Jolla, California. This group of trainees and junior faculty included Steve Heinemann, Rudolf Jaenisch, Inder Verma, Tony Hunter, the late Wylie Vale, and, soon thereafter, Ron Evans. In the years to come, this erstwhile group of young...

BACKGROUND Geographical variation in mortality is influenced by factors operating in early life and in adulthood. The relative contributions of these factors may be examined by comparing the extent to which adult mortality is related to places of residence in early life and at death. We describe a population-based case-control design, in which all deaths are used as cases and the Office for Nat...
