The eighteenth century was an era in which science came to play a major role in the cultural ideal of the city elite. The phenomenon of the ‘gentleman-scientist’ arose: a layman without a scientific education who for a variety of often socially desirable reasons devoted himself to scientific endeavours. Scientific instruments were the tools for this interest. This article describes the introduction, diffusion, and construction in the Netherlands of one of the most prominent eighteenth-century instruments: the reflecting telescope. The reception (...) of this instrument casts new light on the usually almost invisible network of gentleman-scientists and instrument-makers in this region. The specific economic and political factors of the Netherlands led to a totally different development of this instrument compared with the ‘motherland’ England. Whereas in Great Britain the reflecting telescope was a great success well into the nineteenth century, in the Netherlands it became a symbol of technical inability and stagnation. (shrink)

Taking the Royal College of Barcelona (1760–1843) as a case study, this paper shows the development of modern surgery in Spain initiated by the Bourbon Monarchy when they founded new kinds of institutions as academic activities to spread scientific knowledge. Antoni Gimbernat was the most famous internationally recognised Spanish surgeon. He was trained as a surgeon at the Royal College of Surgery in Cadiz and was later appointed Professor of Anatomy at the College of Barcelona. He then became Royal Surgeon (...) of King Carlos IV, and with that esteemed position in Madrid, he worked relentlessly to improve the quality of the Royal Colleges in Spain. Learning human body structure by performing hands-on dissections in the anatomical theatre has become a fundamental element of modern medical education. Gimbernat favoured the study of natural sciences, the new chemistry of Lavoisier and experimental physics in the academic programmes of surgery. According to the study of a very relevant set of documents preserved in the library, the so-called “juntas literarias”, among the main subjects debated in the clinical sessions was the concept of human beings and diseases in relation to the development of the new experimental sciences. These documents showed that chemistry and experimental physics were considered crucial tools to understand the unexplained processes that occurred in the diseased and healthy human body and in a medico-surgical context. It is important to stress that through these manuscripts, we can examine the role and the reception of the new sciences as they were applied to the healing arts. (shrink)

During the mid-18th century, when electricity was coming into its own, natural philosophers began to entertain the possibility that electricity is the mysterious nerve force. Their attention was first drawn to several species of strongly electric fish, namely torpedoes, a type of African catfish, and a South American "eels." This was because their effects felt like those of discharging Leyden jars and could be transmitted along known conductors of electricity. Moreover, their actions could not be adequately explained by popular mechanical (...) theories. Many of the early documents supportive of the hypothesis of animal electricity were associated with the Dutch colonies in South America. This article presents and examines those documents, and shows how Dutch scientists on both sides of the Atlantic conducted experiments and communicated with each other in the 1750s and 1760s. It reveals the important roles played by inquisitive physicians and lovers of nature in South America, and by natural philosophers and collectors of exotic specimens in the Netherlands—learned men who began to make a credible case for animal electricity in some exciting places at a pivotal moment in time.
