Genus Eucalyptus

Resumo As primeiras observações e recolhas de eucaliptos ocorreram nas grandes viagens inglesas e francesas ao Pacífico, em particular à Austrália, em finais do século XVIII. O género Eucalyptus L'Hér. foi estabelecido em 1788, e logo nas duas décadas seguintes seriam descritas, por botânicos franceses e ingleses, muitas espécies novas. O primeiro eucalipto cultivado em Inglaterra foi trazido, em 1774, na segunda viagem de James Cook. Em França, a introdução terá sido feita em 1804, no Jardim Botânico de Montpellier, na Alemanha em 1809, no Jardim Botânico de Berlim, e em Itália, em 1813, no Jardim Botânico de Nápoles. Em Portugal, a introdução do eucalipto foi muito posterior a estas datas. Na propriedade do duque de Palmela no Lumiar, foram plantados dois eucaliptos em 1850-1852. No Horto Botânico da Escola Médico-Cirúrgica de Lisboa, existia em 1852, pelo menos um espécimen, certamente para uso ou demonstração das suas propriedades terapêuticas. A partir da década de 1860, a expansão foi muito rápida. Em 1869, a companhia real dos caminhos-de-ferro portugueses iniciou a plantação de eucaliptos nas estações, casas de guarda e ao longo da via-férrea. As primeiras plantações em larga escala terão ocorrido na década de 1880 em propriedades perto de Abrantes arrendadas por William T. Tait. Em 1886 estavam já plantados 150 mil eucaliptos. Nesta mesma década começou a plantação, em escala apreciável, de eucaliptos nas Matas Nacionais. Em finais do século XX, tinham sido introduzidas em Portugal cerca de 250 espécies, sendo o Eucalyptus globulus Labill., a espécie largamente dominante. É interessante constatar que tendo sido um dos países europeus que mais tarde introduziu a cultura do eucalipto, Portugal é hoje, a nível mundial, um dos que apresenta maior percentagem da sua área florestal dedicada a esta cultura.Palavras-chave: eucalipto; jardins botânicos; Portugal. Abstract The earliest observations and collections of eucalypts occurred on the great English and French voyages to the Pacific, particularly Australia, in the late 18th century. The genus Eucalyptus L'Hér. was described in 1788, and soon in the following two decades, many species would be described by French and English botanists. The first eucalypt grown in England was brought in 1774 on James Cook's second voyage. In France, the introduction seems to have occurred in 1804, at the Botanical Garden of Montpellier, in Germany in 1809, at the Botanical Garden of Berlin, and in Italy, in 1813, at the Botanical Garden of Naples. In Portugal, the introduction of eucalypts was much later than these dates. In the property of the Duke of Palmela in Lumiar, two eucalypts were planted in 1850-1852. The Botanical Garden of the Medical-Surgical School of Lisbon had in 1852, at least one specimen, certainly for use or demonstration of its therapeutic properties. From the 1860s the expansion was very rapid. In 1869, the royal company of the Portuguese railways began planting eucalypts in the stations, guard houses and along the railroad. The first large-scale plantations occurred in the 1880s in properties near Abrantes leased by William T. Tait. By 1886, 150,000 eucalypts were already planted. In the same decade began the planting, on an appreciable scale, of eucalypts in “Matas Nacionais”. By the end of the 20th century about 250 species had been introduced in Portugal, being Eucalyptus globulus Labill., the species largely dominant. It is interesting to note that Portugal, one of the European countries that later introduced the eucalypt, is today, worldwide, one of the countries with the highest percentage of its forest area dedicated to this culture.

Abstract. Natural proxies, documentary evidence and instrumental data are the main sources used to reconstruct past climates. In this paper, we present the 18th century meteorologists (either Portuguese or foreigners), who made the first observations at several sites in Continental Portugal, Madeira Island and Rio de Janeiro (Brazil), from 1749 until 1802. Information is given concerning observation site, variables observed, measurement period, methodologies and sources (both manuscript and printed). Some examples from the data usefulness are given: rainfall variability in Madeira (1749–1753) and in Continental Portugal (1781–1793) was reconstructed, allowing to extend towards the late 18th century the well known negative correlation between the NAO index and seasonal rainfall. Furthermore, previously unpublished data for 1783–1784 has allowed analysing the consequences of the Laki eruption in Portugal: foggy and haze days are referred to in summer 1783, but unlike the hot summer observed in Northern and Central Europe, temperatures in Portugal were lower than average. Additionally, observations from Rio de Janeiro in Brazil show that the Laki consequences may well have spread to sectors of the Southern Hemisphere. Although the series are short, the data will be used for climate reconstruction studies focused in Southern Portugal and are also useful to improve the quality of large scale reconstruction datasets.

Summary ‘First contact’ artefacts collected from aboriginal peoples by the early European explorers are now valuable in providing the only direct evidence for recent ‘Stone Age’ technologies which no longer exist. During the J770's Dr William Hunter collected many such artefacts for his private museum; most originated in the Pacific and in North America and had been collected by people who sailed with Captain James Cook. Since 1978 it has been possible to re-identify most of this early ethnographical material and to separate itfrom later acquisitions. To emphasise the archaeological relevance of this examples are described here from 18th century hunter-gatherer peoples (the Indians of Tierra delFuego, theNootka of British Columbia and the Eskimos of Alaska) and from stone-using farmers (the Maoris of New Zealand and the islanders of Hawaii). A list of the surviving early collection is given in microfiche.

Hydrologic System

Abstract. This paper assesses changing norms of water use known as the duty of water. It is a case study in historical socio-hydrology, a line of research useful for anticipating changing social values with respect to water. The duty of water is currently defined as the amount of water reasonably required to irrigate a substantial crop with careful management and without waste on a given tract of land. The historical section of the paper traces this concept back to late-18th century analysis of steam engine efficiencies for mine dewatering in Britain. A half-century later, British irrigation engineers fundamentally altered the concept of duty to plan large-scale canal irrigation systems in northern India at an average duty of 218 acres per cubic foot per second (cfs). They justified this extensive irrigation standard (i.e., low water application rate over large areas) with a suite of social values that linked famine prevention with revenue generation and territorial control. Several decades later irrigation engineers in the western US adapted the duty of water concept to a different socio-hydrologic system and norms, using it to establish minimum standards for water rights appropriation (e.g., only 40 to 80 acres per cfs). The final section shows that while the duty of water concept has now been eclipsed by other measures and standards of water efficiency, it may have continuing relevance for anticipating if not predicting emerging social values with respect to water.

The 19Th Century

It is generally accepted by scholars that potatoes were first introduced to New Zealand in the late 18th century by Captain James Cook and the French explorer, Marion du Fresne. Further introductions of potatoes from a variety of sources including possible direct introductions from South America, followed into the 19th century. Maori were quick to recognize the advantages that these new introductions had over their traditional food crops including kumara (sweet potato) Ipomoea batatas and Taro Colocasia esculentum both of which they introduced from east Polynesia some 800-100 years previously. Potatoes soon became a staple item in the Maori diet and an important trade commodity and by the mid-19th century they were growing thousands of hectares of potatoes for that purpose. The various cultivars that were introduced were given Maori names and many of these early types are still grown by Maori, having been passed down through families for many generations. With their deep set eyes, often knobbly irregular shape, "open" leaves and colourful tubers these "Maori Potatoes" are quite distinctive in appearance from modern potatoes and some retain many of the features of Solanum tuberosum subsp. andigena types. This paper discusses the adoption of the potato by Maori, the effects it had on Maori society and the perpetuation of the early cultivars within Maori families and communities. This examination of an introduced crop plant and its intersection with an indigenous people is essentially an ethnobotanical study which in addition to its botanical and anthropological foci includes elements of Matauranga Maori (traditional Maori knowledge) history, geography and horticulture. The preservation of these old potato cultivars by generations of Maori people has made a valuable contribution to conservation of biological diversity.

Poetic Imagination

ABSTRACT Although recent scholarship has witnessed a welcome disavowal of the view that Schubert's formal and tonal designs in sonata form compositions bespeak the song composer's inability to master large-scale instrumental genres, it remains a commonplace to characterize Schubert's unorthodox practice as ““lyrical.”” Yet the historical, theoretical, and aesthetic bases of this lyricism have received little critical attention. A systematic and historically grounded approach to the notion of lyrical form in Schubert may be established by appealing to the rhetorical distinction between hypotaxis and parataxis, which pervaded late 18th-century discussions of both music and language. In particular, parataxis, a style that deliberately omits syntactical connections and relies instead on juxtaposition and parallelism, offers a suggestive technical link between Schubert's instrumental practice and the discursive techniques of contemporaneous lyric poetry. There are also aesthetic connections between idealist views of the lyric and the composer's own artistic beliefs, as confirmed by biographical documents. Schubert's approach to form was as much informed by these literary sensibilities as by the Classical compositional tradition. Like poets for whom the lyric served both as an Arcadian ideal of song and as an alternative to the prosaic realities of the present, Schubert evoked the lyric within the context of the sonata as a means of reunifying the dissociated sensibility of the Enlightenment. In so doing, he secured a place for the poetic imagination in instrumental music.

Bleaching Treatment

AbstractThe treatment of a large-scale late 18th-century landscape view is described, focussing on a bleaching treatment. The hand-coloured aquatint Panorama de Chaumont is owned by the Bibliothèque cantonale et universitaire in Neuchâtel, Switzerland. It had been mounted on a wooden strainer and framed without glazing; severe and uneven browning made it unsuitable for presentation. The discolouration resulted from light exposure and direct contact with a wooden strainer which released volatile organic compounds. To minimize the discolouration, the six parts of the print were dismounted and separated along the joints from each other. The pieces were deacidified in tap water. Only one segment was bleached at first with a 0.1% potassium permanganate solution. However, large areas of blue colouring were decolourized during the subsequent sodium dithionite treatment. The decolourized areas of the print recovered their previous blue tone during the following rinsing in water and drying. The unexpected effect was caused by the reduction of indigo to indigo white (leuco-indigo) and its subsequent re-oxidation to indigo in absence of the reducing agent and through impact of atmospheric oxygen. Being able to assess the variables after a first testing phase, all print segments were finally bleached with a 1% potassium permanganate solution. The sheets were deacidified aqueously, resized on the verso with a 0.8% gelatine solution and tears were repaired. The image segments were not rejoined contrary to conservation recommendations.

Erasmus Darwin

Erasmus Darwin was the focus and embodiment of provincial England in his day. Renowned as a physician, he spent much of his life at Lichfield. He instigated the founding of the Lichfield Botanic Society, which provided the first English translation of the works of Linnaeus, and established a botanic garden; the Lunar Society of Birmingham; the Derby Philosophical Society; and two provincial libraries. A list of Darwin's correspondents and associates reads like a "who's who" of eighteenth century science, industry, medicine and philosophy. His poetry was also well received by his contemporaries and he expounded the evolutionary principles of life. Darwin can be seen as an English equivalent of Lamarck, being a philosopher of nature and human society. His ideas have been linked to a multitude of movements, including the nosological movement in Western medicine, nineteenth century utilitarianism, Romanticism in both Britain and Germany, and associationist psychology. The relationships between various aspects of Darwin's interests and the organizational principles of his writings were examined. His poetical form and medical theory were not peripheral to his study of nature but intrinsically linked in providing his contemporaries with a panorama of nature. A richer, more integrated comprehension of Erasmus Darwin as one of the most significant and representative personalities of his era was presented.

The Common

The reception of common law in the United States was stimulated by a very popular and influential treatise Commentaries on the Laws of England by Sir William Blackstone, published in the late 18th century. The work of Blackstone strengthened the continued reception of the common law from the American colonies into the constituent states. Because of the large measure of sovereignty of the states, common law had not exactly developed in the same way in every state. Despite the fact that a single common law was originally exported from England to America, a great variety of factors had led to the development of different common law rules in different states. Albert W. Alschuler from University of Chicago Law School is one of the contemporary American professors of law. The part of his works can be assumed as academic historical-legal narrations, especially those concerning Blackstone: Rediscovering Blackstone and Sir William Blackstone and the Shaping of American Law. Alschuler argues that Blackstone’s Commentaries inspired the evolution of American and British law. He introduces not only the profile of William Blackstone, but also examines to which extent the concepts of Blackstone have become the basis for the development of the American legal thought.
