scholarly journals The spectrum of the flame of carbon disulphide

The present investigation of the spectrum of the flame of carbon disulphide was undertaken in the hope that further light might be thrown on the process of combustion of this substance. Extensive experiments have been made in the past, chiefly relating to explosions of mixtures of carbon disulphide and other gases, but a perusal of the literature suggests that the nature of the reactions which take place in such experiments, or in the ordinary flame itself, is still somewhat obscure. In connection with such experiments as have been made by chemists, the only reference to observations with the spectroscope seems to be that made by Dixon and Russell, who stated that when CS 2 was burnt in a Smithell’s flame separator, an apparently continuous spectrum was yielded by both the inner and outer cones. On the other hand, the spectrum of the CS 2 flame has been described by several spectroscopists, but the records have been incomplete and further observations seemed to be desirable. In particular, observations over a greater range of spectrum seemed to be necessary, as well as more exact measurements of the bands already known to be emitted. With such extended observations it appeared possible that our present knowledge of the band spectra associated with molecules of sulphur and carbon, and some of their compounds, might aid in tracing the reactions which precede the formation of the final products of combustion.

The purpose of this paper is to place on record several discoveries of Neolithic pottery and flint implements which have been made in East Kent during the past seventy years. The preservation of most of the pottery is due to our late Fellow Mr. W. P. D. Stebbing of Upper Deal, who also possessed a manuscript notebook kept by the late Captain C. F. Newington giving details of the finds. Mr. Stebbing also conducted a rescue excavation of the pit at Ramsgate, and kept the fragments of pot and parts of two human skulls. On the other hand, the bulk of the flint implements had been given on various occasions to the Corporation of Deal, and formed part of a collection of local antiquities housed in the Town Hall at Deal.

Abstract The opportunity of exhibiting in a Bororo village in Central Brazil the film Matto Grosso, the Great Brazilian Wilderness (1931), and translating into Portuguese this typical travelogue and widely considered to be the first documentary with synchronized sound, led the authors to analyze visual images on the Bororo society made in the first decades of the XX century. The article focuses on how visual images - films and photographs - frequently show the intentions of the author and on the other hand may enhance memories and create a particular relationship with the past and history of a people.

Seismological compilations of the past two centuries have represented one of the main sources of supporting data for the compilers of current parametric earthquake catalogues, On the one hand, their quality and reliability was proved as varied and, in many cases, fairly low; on the other hand, it is not clear whether all the earthquake records they supply have been exploited to become part of the present knowledge of the historical seismicity of some European countries. This paper analyses one of these compilations, Die Erdbeben von Tirol und Vorarlberg, published in 1902 by J. Schorn, which covers an area today shared among Austria, Switzerland and Italy, with the aim of checking its reliability and its usefulness towards a revision of the knowledge on the seismicity of historical "Tyrol".

In the past decade, the attention to the Calabrian mafia, the ‘ndrangheta, has been rekindled everywhere in the world. On the one hand, Italian attention to the phenomenon has increased; on the other hand, the mobility of the Calabrian clans has been the object of scrutiny in view of the clan’s wealth and ability to commit transnational criminal activities. This has also fed the presumption that (alleged) offenders of Calabrian origins around the world must belong to, and replicate the structure of, the ‘ndrangheta clans, also down under. This contribution will be a reflection on the difficulties and the complexities of a journey into researching the ‘ndrangheta in Australia from a criminological–anthropological perspective, in consideration of—but in contrast with—the mythical figures associated with the Calabrian mafia and its illicit global markets. Some of the difficulties, as well as some of the mistakes that I have made in this research, because of the involuntary (and disorganized) nature of the ethnography, directly question the narrative of the illegal global reach of this mafia and provide methodological reflections and lessons for criminological ethnographies.

This paper explores Arnold Schoenberg’s curious ambivalence towards Haydn. Schoenberg recognized Haydn as an important figure in the German serious music tradition, but never closely examined or clearly articulated Haydn’s influence and import on his own musical style and ethos, as he did with many other major composers. This paper argues that Schoenberg failed to explicitly recognize Haydn as a major influence because he saw Haydn as he saw himself, namely as a somewhat ungainly, paradoxical figure, with one foot in the past and one in the future. In his voluminous writings on music, Haydn is mentioned by Schoenberg far less frequently than Bach, Mozart, or Beethoven, and his music appears rarely as examples in Schoenberg’s theoretical texts. When Schoenberg does talk about Haydn’s music, he invokes — with tacit negativity — its accessibility, counterpoising it with more recondite music, such as Beethoven’s, or his own. On the other hand, Schoenberg also praises Haydn for his complex, irregular phrasing and harmonic exploration. Haydn thus appears in Schoenberg’s writings as a figure invested with ambivalence: a key member of the First Viennese triumvirate, but at the same time he is curiously phantasmal, and is accorded a peripheral place in Schoenberg’s version of the canon and his own musical genealogy.

Countries with positive per capita real growth are characterised by positive national savings—including government savings, increases in government investment, and strong increases in private savings and investment. On the other hand, countries with negative per capita real growth tend to be characterised by declines in savings and investment. During the past several decades, Kenya’s emerging economy has undergone many changes and economic performance has been epitomised by periods of stability, decline, or unevenness. This article discusses and analyses the record of economic performance and public finance in Kenya during the period 1960‒2010, as well as policies and other factors that have influenced that record in this emerging economy.

When one hears the term “ground cover,” one immediately thinks of “grasses.” This perception is so deep-seated that paleobotanists even have been overheard to proclaim that “there was no ground cover before grasses.” Today grasses are so predominant in many environments that this perception is perpetuated easily. On the other hand, it is difficult to imagine the absence or lack of ground cover prior to the mid-Tertiary. We tested the hypothesis that different forms of ground cover existed in the past against examples from the Recent and the fossil record (Table 1). The Recent data were obtained from a large number of sources including those in the ecological, horticultural, and microbiological literature. Other data were derived from our knowledge of Precambrian life, sedimentology and paleosols, and the plant fossil record, especially in situ floras and fossil “monocultures.” Some of the data are original observations, but many others are from the literature. A detailed account of these results will be presented elsewhere (Pfefferkorn and LePage, in preparation).

A strange contrast exists in the status of the Christian Church in the past seventy years. On the one hand the Church has clearly lost some of the ground which once appeared to be safely within its possession. On the other hand it has become more widely spread geographically and, when all mankind is taken into consideration, more influential in shaping human affairs than ever before in its history. In a paper as brief as this must of necessity be, space can be had only for the sketching of the broad outlines of this paradox and for suggesting a reason for it. If details were to be given, a large volume would be required. Perhaps, however, we can hope to do enough to point out one of the most provocative and important set of movements in recent history.

When I agreed to present the article as a vehicle for discussion at a session at the EAA's annual meeting in Zadar, Croatia, I decided to approach the question of a European archaeology from what I considered to be the three organizing pillars of archaeological practice: heritage, theory and publications. Heritage is the dominant organizational/legislative framework for archaeological practice, and it is where most of the money is spent. Theory, on the other hand, organizes most of our interpretations of the past, while publications are still the most common way of presenting the results of both heritage work (mostly excavations) and interpretations of that work. In this way I hoped to have encircled the dominant parameters for a diagnosis of the archaeological landscapes in Europe. I assumed that there might be some correlation between the three, and that such observed common trends within two or more variables would strengthen the argument, to paraphrase processual jargon.

The author analysed the language of the first Polish translation of the eighteenth-century poem “Metai” [The Seasons] by Kristijonas Donelaitis, a Lithuanian Lutheran pastor. The translation was made in 1933 by a socialist activist and close associate of Józef Piłsudski, Kazimierz Pietkiewicz. The analysis showed that the language of the translation is peculiar. On the one hand, this peculiarity consists in refraining from archaizing the translation and the use of elements that are close to the translator’s style of social-political journalism (e.g., dorobkiewicz [vulgarian], feministka [feminist]), on the other hand, the presence at all levels of language of peculiarities characteristic for Kresy Polish language in both its territorial variations. These are generally old features of common Polish, the retention of which in the eastern areas of the Polish Rzeczpospolita was supported by the influence of substrate languages, later also Russian, or by borrowing. This layer was natural in the language of the translator, born in Ukraine, who spent part of his life in Vilnius, some in exile in Russia. This is the colourful linguistic heritage of the former Republic of Poland.
