Corundum xenocrysts from alkaline basalt fields differ in characteristics and hence lithospheric origins. Trace element, fluid/melt inclusion and oxygen isotope studies on two eastern Australian corundum deposits are compared to consider their origins. Sapphires from Weldborough, NE Tasmania, are magmatic (high-Ga, av. 200 ppm) and dominated by Fe (av. 3300 ppm) and variable Ti (av. 400 ppm) as chromophores. They contain Cl, Fe, Ga, Ti and CO2-rich fluid inclusions and give δ18O values (5.1–6.2‰) of mantle range. Geochronology on companion zircons suggests several sources (from 290 Ma to 47 Ma) were disrupted by basaltic melts (47 ± 0.6 Ma). Gem corundums from Barrington, New South Wales, also include magmatic sapphires (Ga av. 170 ppm; δ18O (4.6–5.8‰), but with more Fe (av. 9000 ppm) and less Ti (av. 300 ppm) as chromophores. Zircon dating suggests that gem formation preceded and was overlapped by Cenozoic basaltic melt generation (59–4 Ma). In contrast, a metamorphic sapphire-ruby suite (low-Ga, av. 30 ppm) here incorporates greater Cr into the chromophores (up to 2250 ppm). Fluid inclusions are CO2-poor, but melt inclusions suggest some alkaline melt interaction. The δ18O values (5.1–6.2‰) overlap magmatic sapphire values. Interactions at contact zones (T = 780–940°C) between earlier Permian ultramafic bodies and later alkaline fluid activity may explain the formation of rubies.

The Denchai gem sapphire deposits in Phrae Province, northern Thailand are closely associated with late Cenozoic alkaline basaltic rocks. The sapphires occur in alluvial placer deposits in palaeo-channels at shallow depths. Electron microprobe analysis of minor and trace element contents (Fe, Ti, Cr, Ga and V) of the sapphires indicate the following oxide abundances: Fe2O3 (0.32–1.98 wt.%), TiO2 (0.01–0.23 wt.%), Cr2O3 (<0.01 wt.%), Ga2O3 (0.01–0.03 wt.%) and V2O5 (<0.03 wt.%). Optical studies of sapphires revealed three types of primary fluid/melt inclusions. CO2-rich inclusions (Type I) contain three phases (LH2O + LCO2 + V) with the vapour phase comprising <10–15 vol.%. The presence of CO2 was confirmed by microthermometry and laser Raman analysis. Polyphase inclusions (Type II) (vapour + liquid + solid) contain a fluid bubble (20–30 vol.%), an aqueous phase (10–15 vol.%) and several solid phases. Silicate-melt inclusions (Type III) comprise vapour bubbles, silicate glass and solid phases. Proton-induced X-ray emission (PIXE) analysis revealed high concentrations of K (~;4 wt.%) as well as Ca (~;0.5 wt.%), Ti (~;1 wt.%), Fe (~;2 wt.%), Mn (~;0.1 wt.%), V (<0.03 wt.%), Rb (~;70 ppm) and Zr (~;200 ppm) in the silicate glass. The Ga2O3 abundances and Cr2O3/Ga2O3 values (<1) of the sapphires favour their formation by magmatic processes. The presence of CO2-rich fluids and high K concentrations in the silicate melt inclusions link the origin of the Denchai gem sapphires to CO2-rich alkaline magmatism.

Geochemical characteristics and rare-earth element (REE)-bearing minerals of calc-alkaline granites in southern Myanmar were investigated to identify the minerals controlling fractionation between light and heavy REE (LREE and HREE) during magmatic differentiation and weathering. The granites were classified on the basis of the mineral assemblages into two contrasting groups: allanite-(Ce)- and/or titanite-bearing granites; and more HREE-enriched granites characterized by hydrothermal minerals including synchysite(Y), parisite-(Ce), bastnäsite-(Ce), xenotime-(Y), monazite-(Ce), Y-Ca silicate, waimirite-(Y) and fluorite. This suggests that allanite-(Ce) and titanite are not stable in differentiated magma and HREE are eventually preferentially incorporated into the hydrothermal minerals. The occurrence of the REE-bearing minerals is constrained by the degree of magmatic differentiation and the boundary of two contrasting granite groups is indicated by SiO2 contents of ∼74 wt.% or Rb/Sr ratios of ∼3–8. Fractionation between LREE and HREE during weathering of the granites is influenced by weathering resistance of the REE-bearing minerals, i.e. allanite-(Ce), titanite, the REE fluorocarbonates and waimirite-(Y) are probably more susceptible to weathering, whereas zircon, monazite-(Ce) and xenotime-(Y) are resistant to weathering. Ion-exchangeable REE in weathered granites tend to be depleted in HREE relative to the whole-rock compositions, suggesting that HREE are more strongly adsorbed on weathering products or that HREE remain in residual minerals.

Pink-headed Duck Rhodonessa caryophyllacea is a Critically Endangered species that has not been confirmed in the wild since 1948–1949. Historical records of the species are concentrated in India, although there are also a few from Myanmar. Between 2003 and 2005, BirdLife International and the Biodiversity and Nature Conservation Association (BANCA) conducted a series of field surveys of wetland habitats in the lowlands of Kachin state, an area with a cluster of historical records of the species. These were the first targeted efforts to assess the status of the species in Myanmar. These surveys were complemented by reviews of museum specimens and literature relating to the species in Myanmar. Two specimen records represent very strong evidence that the species occurred in Myanmar historically, although they shed little light on its seasonal status in the country. The surveys conducted by BirdLife International and BANCA were unable to confirm the continued occurrence of Pink-headed Duck in Myanmar. However, they did generate a limited amount of equivocal direct evidence, most notably two possible but unconfirmed sightings. There are several reasons for believing that the species may still persist in the lowlands of Kachin state and, perhaps, elsewhere in Myanmar. Shyness, combined with rarity, possible nocturnal habits and the impenetrability of its habitats, means that the species tended to be under-recorded historically, and may continue to be so currently. Further surveys are required to confirm this.

Wollstonecraft's early works express a coherent view of moral psychology, moral education and moral philosophy which guides the construction of her early fiction and educational works. It includes a valuable account of the relation between reason and feeling in moral development. Failure to recognize the complexity and coherence of the view and unhistorical readings have led to mistaken criticisms of Wollstonecraft's position. Part I answers these criticisms; Part II describes and textually supports her view.

Myanmar, until recently known as Burma, is a developing nation in south-east Asia. Burmese kings and emperors ruled this land until 1885, when it fell into the hands of the British. It gained its independence in 1948. Burma has a mainly agricultural economy and has a rich fertile soil. At one stage in the post-war history Myanmar was renowned as ‘the rice bowl of the world’. It is blessed with abundant natural resources such as teak and precious stones. Myanmar covers a land area twice that of the British Isles with a population of around 42 million.

This paper proceeds from a sense of dissatisfaction with much of current moral argument about defence policy, in particular the role of nuclear weapons. Discussions of the moral issues tend to divide into two distinct kinds of writing: on the one hand, impassioned calls to action based on and allied with equally impassioned moral exhortations; and on the other hand, usually in academic contexts, meticulous analyses and comparisons of aspects of nuclear policy with paradigm cases of acknowledged moral categories or requirements, with the object of showing by analogy with these that the particular aspect of policy under discussion is or is not morally wrong. My unease is caused by the fact that, while it is difficult not to respond to the impassioned style of argument, as one recognizes in it a practical and moral urgency which our situation seems to demand, nevertheless it plainly appeals only to those already convinced of its conclusions. The unconverted tend to regard it with suspicion or disdain, for in contrast to the analytical style, which manifestly seeks to compel the intellect, the impassioned style seems to make its effect by stirring the emotions as much as if not instead of by compelling the intellect. On the other hand the analytical style can seem curiously irrelevant, even trivial, in relation to the issue. For instance, it has been argued that since: nuclear war is a moral disaster; deterrence is threatening or intending to wage nuclear war; it is wrong to threaten or intend to do something wrong; therefore: deterrence is wrong, and should be abandoned. It is hard to believe that defenders of deterrence as the cornerstone of defence policy are going to be persuaded by such an argument to abandon their advocation of it, if only because the argument totally ignores the object of deterrence.

The familial incidence of affective illness is well documented. Many studies have shown identical twins to be highly concordant for affective illness (e.g. Price, 1968; Tsuang, 1977). Suicide is strongly linked with affective disorder. However, few cases of both twins committing suicide have been described, and the family reported here, in which several other members also committed suicide by violent means, is thought to be of considerable interest.

Should the insane and the mentally ill be held morally responsible for their actions? To answer ‘No’ to this question is to classify the mentally abnormal as not fully human: and indeed legal tradition has generally oscillated between assimilating the insane to brutes and assimilating them to children below the age of discretion, neither of these two categories being accountable in law for what they do. In what respect relevant to moral responsibility were the insane held to resemble brutes and children? In the case of brutes, the answer seems to have been that the doings of the insane appeared to lack whatever it is that marks out human actions as distinctively human. What the insane did could not be thought of as issuing from deliberation, or as capable of having issued from deliberation, but seemed rather to be the result of the unbridled operation of nature — if a diseased nature. The natural comparison with insane killings seemed to be, for example, the killing of birds by cats. This distinction between animal doings and human actions does not depend on Cartesian views about the workings of animals; the operation of nature need not be thought of as mechanical. The thought is simply that where there is no room for deliberation there is no room for moral appraisal. Children, on the other hand, though capable of distinctively human action — i.e. of deliberating about what they do — were held not to be capable of the relevant kind of deliberation: for they were held ‘not to know the difference between right and wrong’.

Burmese music is a virgin field for research. Nobody can bewail this virginity more than myself. To help me there does not seem to exist a single western work on Burmese music though there are such classics as Fox Strangways' on Indian and J. H. Levis' on Chinese music. Many writers on Burma have passed remarks, kind or humorous, on Burmese music. But few have attempted a technical study of it. Nothing Burmese escaped the notice of Sir James George Scott, of course. But I know of only two who left some technical remarks on Burmese music: Paul Edmonds, the author of Peacocks and Pagodas; and P. A. Mariano, in an appendix on Burmese music to that most lovingly produced book Burma by Max and Bertha Ferrars.
