Erasmus Darwin (1731-1802) apresentou suas ideias evolutivas principalmente no fim do século XVIII. No entanto, elas não foram consideradas na época. Seu neto, Charles Darwin (1809-1882), na 6ª edição do Origin of species as avaliou de modo negativo, comparando-as às concepções equivocadas de Lamarck. O objetivo desta dissertação é inicialmente, descrever as concepções de hereditariedade e evolução de Erasmus, considerando o contexto de sua época. Além disso, procura esclarecer se o tratamento recebido se deveu a uma proposta fraca ou se ela mereceria uma maior consideração. Esta dissertação contém uma Introdução e quatro capítulos. O Capítulo 1 discute a vida, trabalhos e contexto em que Erasmus apresentou suas ideias. O Capítulo 2 lida com as concepções de herança e evolução presentes em Zoonomia. O Capítulo 3 discute sobre as concepções de Erasmus sobre a transformação das espécies nas plantas. O Capítulo 4 compara as concepções evolutivas de Erasmus com as de Lamarck. O Capítulo 5 procura responder às perguntas colocadas no início desta pesquisa e apresenta algumas considerações finais sobre o assunto discutido. Esta pesquisa leva à conclusão de que a transmutação das espécies não era o principal interesse de Erasmus. Ele não ofereceu uma fundamentação empírica para suas ideias. Este fato, juntamente com a situação sócio-político-religiosa da época, muito provavelmente contribuiu para a recepção sofrida. Além disso, embora existam algumas semelhanças entre as propostas de Erasmus e Lamarck, existem também grandes diferenças tais como a abrangência da pesquisa, o espaço dedicado à discussão das ideias, a fundamentação oferecida, dentre outras. Erasmus não propôs uma teoria coerente lidando com desde a origem da vida até o aparecimento do homem como Lamarck. Ele somente apresentou algumas ideias a esse respeito em obras dedicadas a outros assuntos. / Erasmus Darwin (1731-1802) mainly presented his evolutionary views at the end of the 18th century.

The aim of this dissertation is firstly to describe Erasmus Darwins conceptions on heredity and evolution considering the context of his time. Besides that, it tries to elucidate the reception received by them was due to a weak proposal or whether they deserved greater consideration. This dissertation comprises an Introduction and five chapters. Chapter 1 discusses Erasmus Darwins life, work and the context in which he presented his ideas. Chapter 2 deals with the conceptions of inheritance and evolution which are present in Zoonomia. Chapter 3 discusses Erasmus view on the transmutation of species in plants. Chapter 4 compares Erasmuss evolutionary conceptions to Lamarcks ones. Chapter 5 tries to answer the questions proposed in the beginning of this research and presents some final remarks concerning the subject. This research leads to the conclusion that the transmutation of species was not the main Erasmus concern. He did not present any empirical foundation of his views related to the subject. This fact, together with the socio-political-religious situation, must have contributed to its reception. Besides that, although there were some similarities between Erasmuss and Lamarcks proposal there were also great differences such as the scope of the research, the space dedicated to its discussion, the foundation provided, among others. Erasmus did not provide a coherent theory of the transmutation of species dealing with since the origin of life to the rise of man, departing from a study of natural history such as Lamarck. In this respect, he only presented a few ideas in works dedicated to other subjects.

Henry-Emile Chevalier was forced in exile by the December 1851 Coup d'Etat in France. In March 1853, he came to Montreal and joined Georges-Hippolythe Cherrier who had just started a new periodical called La Ruche Litteraire Illustree. In addition, during his stay in Montreal, Chevalier worked for several periodicals, was an active member of the Institut canadien de Montreal, and wrote many novels and serials depicting Canada's exoticism. This thesis will provide the most accurate biography of Chevalier up to date, it will also present an analysis of the exoticism in his novels and serials (1853-1960), and of his contribution to the evolution of serials in French Canada.

Le mauvais goût de "vase" et de "terre" présent chez les poissons élevés en étangs est causé par la présence de géosmine et de 2-méthylisoboméol (MIB) dans leur chair. Ces composés sont semi-volatiles, et lorsque présents dans l'eau, ils sont absorbés et emmagasinés dans les tissus riches en lipides. Les cyanobactéries planctoniques et -benthiques ainsi que les actinomycètes sont des bactéries reconnues comme étant des sources de géosmine et de MIB. Une période d'épuration en eau fraîche est donc nécessaire pour libérer le poisson de ce mauvais goût. La présence de mauvais goût semblable a déjà été documentée chez les poissons élevés dans un système en recirculation (SR). Toutefois, il existe peu d'information disponible sur l'origine du mauvais goût. Les hypothèses de départ étaient que la durée de l'élimination augmente lorsque la température est réduite, que le taux de lipides contenu dans les tissus augmente et que les composés responsables du mauvais goût chez les poissons élevés en étangs sont les mêmes que chez les poissons élevés en SR. Des méthodes quantitatives (micro extraction en phase solide et GCMS) ont été utilisées pour quantifier et déterminer la source du mauvais goût dans l'eau, dans le biofilm et dans les filets. Les cyanobactéries qui pourraient être responsables de la présence de géosmine n'ont pas encore été identifiées.

En France, les changements sociaux, culturels et politiques du tournant des XVIIIe et XIXe siècles vont imposer au romantisme naissant une autre base d’inspiration que l’Antiquité qui fut celle du classicisme : le Moyen Âge. Victor et Hugo et Honoré de Balzac feront partie des auteurs romantiques qui adapteront les ressources imaginaires des œuvres médiévales dont la figure du chevalier. Pourquoi les romantiques ont-ils perçu en cette figure une source de sens ? Quels sont les aménagements nécessaires pour qu’une figure aussi liée au Moyen Âge soit réactualisée dans l’esthétique romantique? Cette étude se propose de répondre à ces question en observant la figure du chevalier dans des œuvres médiévales, Le chevalier de la charrette (Chrétien de Troyes) et Le Lancelot en prose (auteur inconnu), comparée au chevalier romantique présenté dans La légende du beau Pécopin et de la belle Bauldour (Victor Hugo) et Le frère d’armes (Honoré de Balzac). Cette comparaison permettra de mettre en lumière que cette figure est représentée dans ces œuvres transformée et actualisée. / In France, the social, cultural, and political changes of the turn of the eighteenth and nineteenth centuries will impose on nascent romanticism another basis for inspiration than that of antiquity, which is that of classicism: the Middle Ages. Victor Hugo and Honoré de Balzac will be part of the romantic authors who will adapt the imaginary resources of the medieval works including the knight figure. Why did the romantics observe such a source of sense in this figure? What are the necessary amendments for a symbol so strongly linked to the Middle Ages, required for adapted use in romantic aesthetics? This will be examined through observation of the knight figure in the medieval works, Le chevalier de la charrette (Chrétien de Troyes) and Le Lancelot en prose (unknown author), compared to the romantic knight that is present in La légende du beau Pécopin et de la belle Bauldour (Victor Hugo) and Le frère d’armes (Honoré de Balzac). This comparison will highlight that the symbol of the knight represented in these romantics works is transformed and adapted.
