This paper focuses on the contributions to natural history, particularly in methods of plant classification of the Portuguese botanist, man of letters, diplomat, and Freemason Abbé José Correia da Serra (1751-1823), placing them in their national and international political and social contexts. Correia da Serra adopted the natural method of classification championed by the Frenchman Antoine-Laurent de Jussieu, and introduced refinements of his own that owe much to parallel developments in zoology. He endorsed the view that the classification of plants (...) should be based on the establishment of affinities rather than of differences. The emphasis on affinities went hand in hand with the development of the concept of symmetry. This idea was introduced by Correia da Serra in systematics and was adopted and further developed by his friend, Augustin-Pyramus de Candolle. Correia da Serra also argued that Cryptogamia reproduce sexually, advocated extension of methods of comparative anatomy from zoology to botany, and applied them to the study of fruits. Correia da Serra was one among many of the estrangeirados, Portuguese "Europeanized" intellectuals who traveled extensively abroad in most cases to escape political or religious persecution at home. The estrangeirados were important contributors to 18th and 19th century European thinking. Most of the estrangeirados were pivotal in the introduction, dissemination and propagation of the new sciences in Portugal, but unlike most of his fellow estrangeirados, Correia da Serra was also an innovative man of science in his own right.

ABSTRACT This article aims to defend the dialogical nature of the landscape. Working in between the borders of the Bakhtinian philosophy of language and cultural studies on landscape, we defend that landscape study should not be studied without considering the cultural forms of communication in the different domains of social organization– the speech genres; that landscape is a semiotic encounter with a concrete otherness; that the interpreter who emerges when an area enters a relationship of representation is necessarily characterized as (...) a chronotope; that every landscape is a chronotopic representation; that cultural geography recognizes that the semiotic aspects of the landscape are as material as its morphology. We start from the hypothesis that landscape is a chronotopic representation that is always made possible by means of some speech genre, because it is always a communicative process, and an encounter with another in a situation of socially organized interrelation – it is concrete dialogue. To find the deeper meaning of a landscape, one must recognize and understand its material, historical, geographical, and dialogic nature. RESUMO O artigo objetiva defender a índole dialógica da paisagem. Trabalhando na fronteira entre a filosofia bakhtiniana da linguagem e os estudos culturais da paisagem, defendemos que a paisagem não seja estudada sem considerar as formas culturais de comunicação nos diferentes domínios da organização social – os gêneros discursivos; que toda paisagem é encontro semiótico com uma alteridade concreta; que o intérprete que emerge quando uma área entra em relação de representação é necessariamente caracterizado por um cronotopo; que toda paisagem é representação cronotópica; que a geografia cultural reconheça que os aspectos semióticos da paisagem são tão materiais quanto sua morfologia. Partimos da hipótese de que a paisagem é uma representação cronotópica que sempre se realiza através de algum gênero discursivo, pois sempre é um processo comunicativo e de encontro com o outro em uma situação de inter-relação socialmente organizada – é diálogo concreto. Para adentrar à profundeza de seus sentidos, precisa-se reconhecer e compreender sua índole material, histórica, geográfica e dialógica. (shrink)

Summary During the nineteenth century French chemistry was marked by an outstanding number of Alsation chemists whose scientific contributions cannot be ignored. Especially following the Franco-Prussian War, their regional origin was given a particular importance as a means of affirming their singularity on the French scientific scene. However, some questions may be raised: can we distinguish the Alsatians from other French chemists before 1870? Were they a homogeneous group sharing a common origin? The aim of this article therefore, is, to (...) show that by their theoretical options within chemistry, their personal and professional relationships, as well as by their participation in various common initiatives, they organized themselves both formally and informally within the Parisian scientific community. Amongst these forms of organization the research school of Charles Adolphe Wurtz (1817?84) emerges as the nucleus of what we may envisage as a network of Alsatian chemists working in Paris, in the second half of the nineteenth century.

This paper focuses on the role played by the Geological Survey of Portugal in the emergence and consolidation of geology as a government science in the nineteenth century, within a general policy of control over territory. The period under consideration covers the directorates of its first leaders, Pereira da Costa (1809–1888) and the military engineers Carlos Ribeiro (1813–1882), and Nery Delgado (1835–1908). When the Geological Survey was created in 1857 as part of the Directorate of Geodesic, Chorographic, Hydrographical Works of (...) the Kingdom (Direcção Geral dos Trabalhos Geodesicos, Chorographicos, Hydrographicos do Reino) established at the Ministry of Public Works, Trade and Industry (Ministério das Obras Públicas, Comércio e Indústria), Portugal lacked a geological culture and a tradition in geological research. The Portuguese Geological Survey was to be marked by the idiosyncrasies of the local culture and of the organization of the State. In this paper, the emergence of geology as a government science is analysed, by taking into consideration the structure, organization, and a general overview of contributions to the Survey. A particular emphasis will be given to its subordinate staff—the field assistants—not only because their contributions to the geological knowledge of the country have hitherto been largely ignored, but also because they materialized the only possible way for common people to become involved with geology in nineteenth‐century Portugal. Generally, with only a basic education, field assistants gradually acquired enough expertise to make decisions in the field, and a few of them even became what Nery Delgado termed ‘practical geologists’. The letters in which they reported their work in addition to vivid accounts of less glamorous aspects of fieldwork and its organization provide an image of the country and of its culture by portraying the reactions of civil society to the practice of geology.

This paper focuses on the biography of the Portuguese naturalist Francisco de Arruda Furtado, born on São Miguel Island, in the Azorean archipelago, in 1854, who became part of an international network of naturalists. Despite his short life, he produced original research on malacology, and from his youth Furtado claimed to be a disciple of Darwin. Informed by recent literature reflecting on the resurgence of biography in the history of science, the narrative of Furtado’s life will take into consideration what (...) it meant to be, and the implications of considering oneself, a disciple of Darwin in the nineteenth-century natural sciences. In the history of science, the concept of disciple has often been associated with research schools, but Darwin did not create one and never surrounded himself with young apprentices. In this paper we argue that in Furtado’s case, and in all probability in many others, in addition to being a scientific theory, evolution had the status of a doctrine. As such, Darwinian evolution had a strong ideological and political dimension. By propagating it among lay people it had the potential of changing attitudes individually and socially, while at the same time it provided the scientific foundations for social and political transformation. Consequently, in addition to scientific research based on Darwin’s theory, Furtado deeply engaged in proselytizing the natural sciences and Darwinian evolution, becoming representative of the importance of Darwin’s disciples in Furtado’s sense, in the reception and endorsement of evolution around the world, with repercussions beyond natural history.
