O presente trabalho propõe uma releitura da Micrographia de Robert Hooke, segundo a qual a descrição da estrutura da cortiça não constitui o tema principal que o tornou participante dos debates sobre a história natural no século XVII mas, sim, outras observações, principalmente as de números XIX e XLIII. Na primeira, descreve minuciosamente as formas aquáticas jovens de um mosquito culicídeo (larva e pupa) e sua metamorfose para o estádio adulto. Na segunda, discute o problema da geração espontânea dos insetos. As observações XIX e XLIII evidenciam que Hooke estava consciente dos grandes debates que se travavam na história natural da época. Posicionou-se com clareza em relação à origem do "inseto aquático". Admitiu certos casos de geração espontânea dos insetos como a dos "vermes" das galhas dos vegetais, bem como a "metamorfose" de vegetais em animais. Assim, Robert Hooke pode ser apropriadamente considerado um filósofo natural, detentor de conhecimentos e ideias em todas as áreas das ciências de sua época, nas quais desenvolveu notáveis contribuições.

This article proposes a rereading of the work Micographia by Robert Hooke. It proposes that the main theme from this book that played a part in 17th century debates about natural history was not the description of the structure of cork, but instead other observations made particularly in sections XIX and XLIII. In the first, he describes in minute detail the young of an aquatic mosquito Culicidae (larva and pupa) and its metamorphosis to the adult stage. In the second, he discusses the problem of spontaneous generation of insects. These observations show that Hooke was aware of the great debate taking place in the natural history of the time. He positioned himself clearly on the origin of the "aquatic insect". He acknowledged some cases of spontaneous generation of insects such as "worms" of galls of plants, and the "metamorphosis" of plants in animals. Thus, Robert Hooke, appropriately, can be considered a natural philosopher, who possessed knowledge and ideas in all areas of science of his time, and to which has remarkable contributions.

Os aspectos históricos da medicina animal, examinados mediante revisão de literatura indicam ruptura epistemológica, com as antigas práticas de alveitaria, com introdução dos princípios de racionalidade, a partir do século XVIII, na formação dos médicos-veterinários. Essas práticas curativas, entretanto, não começaram com a implementação dos cursos superiores de medicina animal. No Brasil colonial e particularmente em Pernambuco ocorrem registros históricos de práticas alveitares, mais tarde incorporadas ao currículo da Escola Superior de Medicina Veterinária São Bento de Olinda, pela existência de avaliação única no Brasil: o exame physicum.

The historical aspects of animal medicine indicate an epistemological break with the old practices of animal medical treatment, with introduction of the principles of rationality in the eighteenth century in the formation of veterinary doctors. These healing practices, meanwhile, did not begin with the implementation of graduate courses in animal medicine. In colonial Brazil and, in particular, in the State of Pernambuco, historical records can be found of animal medical practices that were later incorporated into the curriculum of the São Bento de Olinda Graduate School of Veterinary, marked by the presence of a unique evaluation in Brazil: the physicum examination.

The present work proposes the investigation of the role of chemistry in the curriculum of the Higher School of Agriculture "São Bento" (1912-1936) and its function in the education of agronomic engineers. The circumstances under which the Higher Schools of Agriculture and Veterinary Medicine in Olinda were founded at the beginning of the XXth century are discussed. The article further treats the influence of the principles of Justus von Liebig, which were seen at that time as essential for a rational agriculture.

This work is intended to rescue the field of validity of the "Disquisitiones" by the naturalist Arruda da Câmara placing them in the scientific and historical context of the end of the "Century of Light". Thus, a tentative is made here to reconstruct the debate established among the several theories that served as background of the relationships between Chemistry and Physiology of that time. In the present work is presented by the first time an integral translation of the "Disquisitiones" and a biographical resume of the naturalist in the historical context of his epoch in Northeast Brazil, especially in Pernambuco.
