Human radiation for medicine, spiritism and hypnosis in Argentina: scientific controversies around vital radiations (1880-1930).

In the mid-nineteenth century, magnetic theories penetrated other recognized medical practices in Argentina in order to rationalize their procedures, in a culture that accepted and validated magnetism as a positive science. At the start of the twentieth century, mesmerists created a society, published books and journals, and carried out a large welfare programme; there were public lectures, and magnetic treatment for spiritualists and the general public, emphasizing the therapeutic properties of mesmerism. Magnetologists/mesmerists measured vital radiation and built devices using sensitive objects as 'physical' evidence of it. There was an interest in acquiring and using artefacts to measure human radiation useful in medicine. Magnetic practices survived until the end of the 1920s, when they lost importance.

The origins and early years of the Magnetic and Meteorological department at Greenwich Observatory, 1834-1848.

As one of his first acts upon becoming Astronomer Royal in 1835, George Airy made moves to set up a new observatory at Greenwich to study the Earth's magnetic field. This paper uses Airy's correspondence to argue that, while members of the reform movement in British science were putting pressure on the Royal Observatory to branch out into geomagnetism and meteorology, Airy established the magnetic observatory on his own initiative, ahead of Alexander von Humboldt's request for British participation in the worldwide magnetic charting project that later became known as the 'Magnetic Crusade'. That the Greenwich magnetic observatory did not become operational until 1839 was due to a series of incidental factors that provide a case study in the technical and political obstacles to be overcome in building a new government observatory. Airy attached less importance to meteorology than he did to geomagnetism. In 1840, he set up a full programme of meteorological observations at Greenwich - and thus turned his magnetic observatory into the 'Magnetic and Meteorological department' - only as the price of foiling an attempt by Edward Sabine and others in the London scientific elite to found a rival magnetic and meteorological observatory. Studying the origins of Airy's Magnetic and Meteorological department highlights how important the context of other institutions and trends in science is to understanding the development of Britain's national observatory.

Imperceptible signs: remnants of magnétisme in scientific discourses on hypnotism in late nineteenth-century France.

In 1880s France, hypnotism enjoyed unique medico-scientific legitimacy. This was in striking contrast to preceding decades when its precursor, magnétisme animal, was rejected by the medical/academic establishment as a disreputable, supernaturally tinged practice. Did the legitimation of hypnotism result from researchers repudiating any reference to the wondrous? Or did strands of magnetic thinking persist? This article interrogates the relations among hypnotism, magnétisme, and the domain of the wondrous through close analysis of scientific texts on hypnotism. In question is the notion that somnambulist subjects possessed hyperacute senses, enabling them to perceive usually imperceptible signs, and thus inadvertently to denature researchers' experiments (a phenomenon known as unconscious suggestion). The article explores researchers' uncritical and unanimous acceptance of these ideas, arguing that they originate in a holdover from magnétisme. This complicates our understanding of the continuities and discontinuities between science and a precursor "pseudo-science," and, more narrowly, of the notorious Salpêtrière-Nancy "battle" over hypnotism.

Making Kew Observatory: the Royal Society, the British Association and the politics of early Victorian science.

Built in 1769 as a private observatory for King George III, Kew Observatory was taken over in 1842 by the British Association for the Advancement of Science (BAAS). It was then quickly transformed into what some claimed to be a 'physical observatory' of the sort proposed by John Herschel - an observatory that gathered data in a wide range of physical sciences, including geomagnetism and meteorology, rather than just astronomy. Yet this article argues that the institution which emerged in the 1840s was different in many ways from that envisaged by Herschel. It uses a chronological framework to show how, at every stage, the geophysicist and Royal Artillery officer Edward Sabine manipulated the project towards his own agenda: an independent observatory through which he could control the geomagnetic and meteorological research, including the ongoing 'Magnetic Crusade'. The political machinations surrounding Kew Observatory, within the Royal Society and the BAAS, may help to illuminate the complex politics of science in early Victorian Britain, particularly the role of 'scientific servicemen' such as Sabine. Both the diversity of activities at Kew and the complexity of the observatory's origins make its study important in the context of the growing field of the 'observatory sciences'.

Weathering the empire: meteorological research in the early British Straits Settlements.

This article explores meteorological interest and experimentation in the early history of the Straits Settlements. It centres on the establishment of an observatory in 1840s Singapore and examines the channels that linked the observatory to a global community of scientists, colonial officers and a reading public. It will argue that, although the value of overseas meteorological investigation was recognized by the British government, investment was piecemeal and progress in the field often relied on the commitment and enthusiasm of individuals. In the Straits Settlements, as elsewhere, these individuals were drawn from military or medical backgrounds, rather than trained as dedicated scientists. Despite this, meteorology was increasingly recognized as of fundamental importance to imperial interests. Thus this article connects meteorology with the history of science and empire more fully and examines how research undertaken in British dependencies is revealing of the operation of transnational networks in the exchange of scientific knowledge.

John Tyndall and the Early History of Diamagnetism.

John Tyndall, Irish-born natural philosopher, completed his PhD at the University of Marburg in 1850 while starting his first substantial period of research into the phenomenon of diamagnetism. This paper provides a detailed analysis and evaluation of his contribution to the understanding of magnetism and of the impact of this work on establishing his own career and reputation; it was instrumental in his election as a Fellow of the Royal Society in 1852 and as Professor of Natural Philosophy at the Royal Institution in 1853. Tyndall's interactions and relationships with Michael Faraday, William Thomson, Julius Plücker and others are explored, alongside his contributions to experimental practice and to emerging theory. Tyndall's approach, challenging Faraday's developing field theory with a model of diamagnetic polarity and the effect of magnetic forces acting in couples, was based on his belief in the importance of underlying molecular structure, an idea which suffused his later work, for example in relation to the study of glaciers and to the interaction of substances with radiant heat.

Los prodigios del hombre encarnado. Víctor Melcior y la redefinición de la mediumnidad (1901) / The marvels of the incarnated man. Víctor Melcior and the redefinition of mediumship (1901)

A finales del siglo XIX, mediante el estudio científico de los fenómenos espiritistas, nuevos enfoques médicos y psicológicos se aplicaron a la mediumnidad. La idea del médium espiritista fue sustituida por la noción del médium como un ser desequilibrado, capaz de emanar fuerzas psíquicas inconscientemente. Este trabajo analiza la redefinición de la mediumnidad a través de unos polémicos artículos del médico catalán Víctor Melcior. Esta microhistoria sirve, por un lado, para situar el debate local dentro del contexto científico internacional y, así, mostrar las relaciones entre el espiritismo, la medicina y la psicopatología del momento. Por otro lado, permite analizar las reacciones de algunos espiritistas a las teorías de Melcior, así como las consecuencias que este debate tuvo para el espiritismo en general (AU)

Towards the end of the 19th century, new medico-psychological approaches were applied to mediumship through the scientific study of spiritualist phenomena. The spiritualist idea of the medium was replaced with the notion of the medium as an unstable human being capable of emanating psychic forces unconsciously. This paper analyses the redefinition of mediumship through the polemical articles of the Catalan physician Víctor Melcior. On one hand, this microhistory allows the local debate to be placed within the scientific international context, describing the relationships among spiritualism, medicine and psychopathology at that time. On the other hand, it permits analysis of the reactions of some spiritualists to Melciors (AU)

Hansteen's magnetometer and the origin of the magnetic crusade.

In the early nineteenth century, Norwegian mathematician and astronomer Christopher Hansteen (1784-1873) contributed significantly to international collaboration in the study of terrestrial magnetism. In particular, Hansteen was influential in the origin and orientation of the magnetic lobby in Britain, a campaign which resulted in a global network of fixed geomagnetic observatories. In retrospect, however, his contribution was diminished, because his four-pole theory in Untersuchungen der Magnetismus der Erde (1819) was ultimately refuted by Carl Friedrich Gauss in Allgemeine Theorie des Erdmagnetismus (1839). Yet Hansteen's main contribution was practical rather than theoretical. His major impact was related to the circulation of his instruments and techniques. From the mid-1820s, 'Hansteen's magnetometer' was distributed all over the British Isles and throughout the international scientific community devoted to studying terrestrial magnetism. Thus in the decades before the magnetic crusade, Hansteen had established an international system of observation, standardization and representation based on measurements with his small and portable magnetometers.

John Tyndall and the Royal Medal that was never struck.

Just once in its long history has a Royal Medal been awarded but not presented. John Tyndall FRS (1820-93) was the chosen recipient in 1853 for his early work on diamagnetism but declined to accept it. The story of why Tyndall felt compelled to turn down this considerable honour sheds light on the scientific politics and personal relationships of the time, on the importance given to the study of magnetism, and on Tyndall's own character and career.

Proles sine matre creata: el anhelo prometeico en la historia del cuerpo humano en Occidente / Proles sine matre creata: The promethean urge in the history of the human body in the west

Since the beginning of modernity there has been an observable tendency in Western thought to consider the human body as susceptible of technical manipulation, to the extreme of conceiving the possibility of manufacturing it. The figures of the homunculus and the automaton, the heirs of the Golem, represent the clearest embodiment of this aspiration. This paper explores the psychology underlying this plan, based on the psychological theory of C.G. Jung, and developed more recently by J. Hillman, on the hypothesis that the plan involves the denial of the feminine and, therefore, of the more truly psychological aspects of humanity, in the name of a unilaterally rationalistic and materialistic worldview. From the viewpoint of the authors mentioned, the mythical psychological reference capable of providing the fundamental key to this project would be Prometheus (AU)

Desde los inicios de la modernidad puede detectarse en el pensamiento occidental una tendencia a pensar el cuerpo humano como susceptible de manipulación técnica, hasta el extremo de concebir la posibilidad de fabricarlo. Las figuras del homúnculo y el autómata, herederas de la del gólem, representan las cristalizaciones más evidentes de esta pretensión. El presente trabajo pretende explorar la psicología que está en la base de este designio a partir de la teoría psicológica de C.G. Jung desarrollada más recientemente por J. Hillman, sobre la hipótesis de que dicho proyecto implica la negación de lo femenino y, con ello, de los aspectos más propiamente psíquicos de lo humano, al servicio de una cosmovisión unilateralmente racionalista y materialista. El referente mítico –psicológico, en la perspectiva de los autores mencionados- capaz de suministrar las claves profundas de ese proyecto sería Prometeo (AU)

Genealogía hipnótica del mito del zombi: The Magic Island (1929) / Hipnotic Genealogy of the Myth of the Zombie: The Magic Island (1929)

Este es el primero de una serie de artículos en los que se pretende estudiar la historia y la significación psicológica del “mito del zombi” a través del análisis de sus elementos alegóricos y simbólicos partiendo de una conceptualización de “mito” extraída de las nociones de la psicología analítica de Jung y de la historia de las religiones de Eliade. Aquí profundizaremos en la genealogía simbólica que antecede y se inserta en la concepción del zombi en The Magic Island de Seabrook (primer texto donde aparece el zombi como muerto viviente) a través del análisis comparativo con el sonámbulo de la literatura y cinematografía del “lado oscuro del magnetismo animal y la hipnosis” y su relación con el autómata (AU)

This is the first of series of articles that aims to study the history and psychological significance of the “myth of the zombie” through the analysis of its allegorical and symbolic elements, based on a myth’s conceptualization extracted from the notions of Jung’s analytical psychology and Eliade’s history of religions. Here, we’ll look deeply into the symbolic genealogy that comes before and it’s inserted in zombie conception in Seabrook’s The magic island (first text where zombie appears as living dead) through a comparative analysis with the somnambulist in literature and filmography of “the dark side of animal magnetism and hypnosis” and its connection with the automaton (AU)

[Little histories of magnetic cures]. / Petite histoire des remèdes magnétiques.

Men were very early fascinated by magnetism because of its manifest and particular working at distance, which looked different of gravity. It was tryed to be explained by mecanism, for exemple Descartes and Boyle. Paracelse valued the therapeutics with magnets and conceived medicines as working by a magnetic virtue. Gilbert limited the medicinal properties of magnet but helded it to be animated. Many authors praised remedies that work at distance of the evil as Bacon, Van Helmont, Croll, Porta, Goclenius, Digby. Such a belief related to magic ideas of this time. In the Bacon's way Boyle collected facts of magnetic cures, and his actual testing of the divisibility of bodies led him to conceive imponderable corpuscles. Newton supposed a subtil and universel fluid going through every solid body. Mesmer misappropriated this idea by founding the animal magnetism of which physical working was only proceeding from the inside of the patient by an effect of suggestion (psychosomatic). Homeopathy took again the notion of remedies having an infinite or a magnetic virtue, which partly issued from Paracelse's and Mesmer's doctrines, which were extolled in Germany at the time of Hahnemann. The latter decided in favour of a spiritualist and not corpuscular interpretation of the working of his homeopathic medicines.

Skull lichens: a curious chapter in the history of phytotherapy.

Lichens growing on skulls were known in late medieval times as usnea or moss of a dead man's skull and were recommended as highly beneficial in various diseases. They were, in addition, the main ingredient of Unguentum armariun, a liniment used in a curious medical practice: the magnetic cure of wounds. We can place this chapter of the history of phytotherapy within the wider cultural context of the period, which saw the definition of nature become increasingly more fluid and open to a variety of novel interpretations.

Mathematical representations in science: a cognitive-historical case history.

The important role of mathematical representations in scientific thinking has received little attention from cognitive scientists. This study argues that neglect of this issue is unwarranted, given existing cognitive theories and laws, together with promising results from the cognitive historical analysis of several important scientists. In particular, while the mathematical wizardry of James Clerk Maxwell differed dramatically from the experimental approaches favored by Michael Faraday, Maxwell himself recognized Faraday as "in reality a mathematician of a very high order," and his own work as in some respects a re-representation of Faraday's field theory in analytic terms. The implications of the similarities and differences between the two figures open new perspectives on the cognitive role of mathematics as a learned mode of representation in science.
