Clerk Maxwell’s investigation into the constitution and stability of Saturn’s Ring was based upon the fundamental supposition that the rings were composed of particles arranged in concentric circles. Although the particles could perform small oscillations about their mean positions, it is evident that the outline of the ring would be to all appearances circular. A line in Clerke’s ‘Popular History of Astronomy in the Nineteenth Century’ (page 299) suggests that some observers have regarded the outline of the ring as elliptical. It is therefore of interest to enquire under what conditions an elliptical ring could exist. The ellipse is a more general form than a circle. If, therefore, it can be shown that an elliptic ring is possible, any explanation of the origin of the rings must take account of this fact. In this paper a single ring of particles is examined. The actual Ring of Saturn probably consists of numerous rings, one within the other. By their gravitational attraction, each will affect the motions of the others. As a first approximation, however, it is sufficient to consider the case of a single ring.

Much of the critical writingon Queer Theory and Sexuality Studies in a Victorian context over the last decade or so has been absorbing, exploring, complicating, and working under the burden of the influence of Michel Foucault's theoretical writings on erotic relations and identity. The first volume of Foucault'sThe History of Sexuality(1978), in fact, had begun with a gauntlet thrown down before Victorian Studies, a chapter-long critique of Steven Marcus'sThe Other Victorians(1966), a work that had offered an entirely new and at the time, quite bold avenue of exploring nineteenth-century culture – namely, through the pornographic imagination that Marcus taxonomized with precise, clinical flair as a “pornotopia” in which “all men . . . are always infinitely potent; all women fecundate with lust and flow inexhaustibly with sap or both. Everyone is always ready for everything” (276). In Foucault's telling, however, Marcus demonstrated a theoretically impoverished faith in Freudian models of “repression” in Marcus's examination of “underground” Victorian sexualities. It was Marcus's reliance on the “repressive fallacy,” his conviction that there existed a demarcated spatial and psychic Victorian counter-world thatThe History of Sexualityhad so forcefully undermined.

The reception of Mendeleev’s periodic system in Sweden was not a dramatic episode. The system was accepted almost without discussion, but at the same time with no exclamation marks or any other outbursts of enthusiasm. There are but a few weak short-lived critical remarks. That was all. I will argue that the acceptance of the system had no overwhelming effect on chemical practice in Sweden. At most, it strengthened its characteristics. It is actually possible to argue that chemistry in Sweden was more essential for the periodic system than the other way around. My results might therefore suggest that we perhaps have to reevaluate the role of Mendeleev’s system in the history of chemistry. Chemistry in Sweden at the end of the nineteenth century can be characterized as a classifying science, with chemists very skilled in analysis, and as mainly an atheoretical science, which treated theories at most only as hypothesis—the slogan of many chemists being “facts persist, theories vanish.” Thanks to these characteristics, by the end of the nineteenth century, chemistry in Sweden had developed into, it must be said, a rather boring chemistry. This is obviously not to say that it is boring to study such a chemistry. Rather, it gives us an example of how everyday science, a part of science too often neglected but a part that constitutes the bulk of all science done, is carried out. One purpose of this study is to see how a theory, considered to be important in the history of chemistry, influenced everyday science. One might ask what happened when a daring chemistry met a boring chemistry. What happened when a theory, which had been created by a chemist who has been described as “not a laboratory chemist,” met an atheoretical experimental science of hard laboratory work and, as was said, the establishment of facts? Furthermore, could we learn something about the role of the periodic system per se from the study of such a meeting? Mendeleev’s system has often been considered important for teaching, and his attempts to write a textbook are often taken as the initial step in the chain of thoughts that led to the periodic system.

Chandrasekhar's own books, papers, and oral history interviews make clear that he was generally more interested in the present and future of astrophysics than in its past. Nevertheless, late in his life and after his death, historians of science have somewhat entangled him in two supposedly controversial issues, one concerning precursors of his mass limit for degenerate stars and the other his relationship with Eddington. Neither story is an entirely happy one.

ABSTRACTThe recent bicentennial commemorations of the Napoleonic empire have witnessed a proliferation of new studies. Scholars now possess much more sophisticated conceptual tools than in past decades with which to gauge the problems faced by French imperial administrators throughout Europe. Well-trodden concepts, like centre/periphery or collaboration/resistance, have been reinvigorated by more sophisticated understandings of how rulers and ruled interacted in the early nineteenth century. This article argues that, while much progress has been made in understanding problems of ‘resistance’, there is more to be said about the other side of the same coin, namely: ‘collaboration’. Using the micro/local history of a scandal in Napoleonic Bologna, this article wishes to reaffirm that collaboration was an active agent that shaped, and often shook, the French imperial project. The biggest problem remained that, despite ‘good intentions’, collaborators sometimes simply did not collaborate with each other. After all, imperial clients were determined to benefit from the experience of empire. The centre was often submerged by local petty squabbles. This article will use a specific micro-history in Bologna to highlight the extent to which Napoleonic empire builders had to thread a fine line between the impracticalities of direct control and the dangers of ‘going native’.

One of the striking facts about the social and political history of Haiti from independence in 1804 to the present is the deep gulf separating the largely mulatto elite groups from the predominantly black masses. The war of the South in 1799 between Toussaint and Rigaud, and the conflicts between Christophe and Pétion, while not primarily caused by color factors, were reinforced by suspicions and hostilities between black and mulatto, with each group accusing the other of prejudice and discrimination. Politics in the rest of the nineteenth century can generally be seen as a tussle between a mulatto elite centered in the capital and in the cities of the South, on the one hand, and a small black elite often in alliance with army leaders and peasant irregulars, on the other. In the years following 1867 these groups formalized themselves into a largely mulatto Liberal Party, and a preponderantly black National Party.

Hunting Ground

Psychology was for centuries a part of philosophy, the happy, undisputed hunting-ground of the speculative metaphysician. With the beginning of the nineteenth century a new era dawned gradually for psychology. Anatomists, physiologists and physicists began to invade this reserve of the metaphysician. These early attempts of Gall and Spurzheim, Johannes Müller, E. H. Weber, Du Bois Reymond, Helmholtz, Lotze, Fechner, Thomas Young and many others are too well known to detain us. They lead up to the work of Wilhelm Wundt and the establishment of psychology as one of the natural sciences, from speculation without facts to speculation allied with experiment. However, as usually happens, the swing of the pendulum goes from one extreme to the other. For whilst the metaphysical psychologist would ignore physiology and neurology, maintaining that what is not itself a phase of consciousness cannot be used to explain consciousness, some of the physiological psychologists would overshoot the mark and attempt a psychology without consciousness. Thus we find the behaviourists (Watson) and the objective psychologists (Bechterew). Pavlov appears to belong to the latter school. But as Prof. Brett, in his History of Psychology, rightly says: “Modern psychology lies between two points: it emerges from anatomy and physiology, and terminates in a region where those sciences cease to guide.”

Parallel Fashion

The garment industry is a good example of the relative autonomy of academic fields. Two histories of the industry are being written simultaneously but separately. One is a history of women; the other, a history of immigrants. Two types of workers have indeed come to the sweatshops, and each have had distinct reasons for doing so. The nineteenth century saw the shift from tailormade to ready-made garments, from the (hand-held) needle to the sewing machine, from tailors and dressmakers to garment workers, and from more to less skill in the making of clothing. The ready-to-wear revolution was also accompanied by a global shift in the sewing labor force, from men to women and from natives to immigrants. The story is a complicated one, yet one which has most often been told in parallel fashion.

Political Oratory

It has never been established how far, in the early Victorian House of Commons, voting on issues followed party lines. It might in general seem plausible to assume — what political oratory generally contrives to suggest — that there are ideological disagreements between parties and that it makes a difference which of two major opposing parties is in control of the Government. This is, indeed, the line taken by some students of politics. A number of historians and political observers have, however, inclined to the contrary opinion and have, for various reasons, tended to play down the role of issues in party disputes. Much of what has been written on political history and, in particular, on the history of Parliament has had a distinct anti-ideological flavor.One line of argument is that issues on which disagreement exists are not always party questions. Robert Trelford McKenzie begins his study of British parties by pointing out that Parliament just before 1830 was “divided on a great issue of principle, namely Catholic emancipation,” and just after 1830, on another, parliamentary reform. He continues: “But on neither issue was there a clear division along strict party lines.” The distinguished administration of Sir Robert Peel in the 1840s was based, according to Norman Gash, on a party “deeply divided both on policy and personalities.” The other side of the House at that time is usually thought to have been even more disunited. It has even been suggested that, in the confused politics of the mid-nineteenth century, the wordsconservativeandradicaleach meant so many different things that they cannot be defined in terms of programs and objectives and that these polarities may more usefully be considered in terms of tempers and approaches.

Intense Debate

This paper deals with one of the first attempts to measure simple reactions in humans. The Swiss astronomer Adolph Hirsch investigated personal differences in the speed of sensory transmission in order to achieve accuracy in astronomy. His controversial results, however, started an intense debate among both physiologists and astronomers who disagreed on the nature of these differences. Were they due to different eyes or brains, or to differences in skill and education? Furthermore, they debated how to eliminate them. Some, for example, wanted to eliminate the observer, and prescribed the use of new technologies like the electro-chronograph or photography, while others believed in discipline and education. By debating the nature of these differences, astronomers and physiologists sketched both different conceptions of ‘man’ and different paths to objectivity. These diverse conceptions, moreover, were tied to current nineteenth-century debates, such as the benefits or disadvantages of railroads, telegraphy and the standardization of time and longitudes. By focusing on the debates surrounding the speed of sensory transmission, this paper reevaluates the history of astronomy, physiology and experimental psychology. Furthermore, in investigating astronomy's relation to the human sciences, it uncovers profound connections in the traditionally separate histories of objectivity and the body.L'heure sera distribuée dans les maisons,comme l'eau ou le gaz.Adolph Hirsch
