In 1890 the staff of the Dublin Natural History Museum began a comprehensive rearrangement of the collection in their care. Inspired by visits to American museums and motivated by a desire to produce a truly educational display, curators arranged the zoological collection to include cases on the history and geographical distribution of animals. These cases explicitly depicted, in words and specimens, the main arguments of Charles Darwin's On the Origin of Species. Placed at a ground-floor entrance to the museum, the cases invited the visitor to examine the remainder of the collection in terms of evolution by natural selection. The exhibit was supplemented by guidebooks and several lecture-demonstrations, which served to further reinforce its messages. Through an analysis of the exhibit's development and contents, this paper will show how these cases reflected not only the status of evolutionary thinking in Ireland, but also the curators' goals for the future development of Irish natural history.

In many areas the eighteenth century was a starting point for the quantification of science. It was a period in which the mania for collecting led to the first attempts in systematization and classification. This penchant for collecting was not limited to natural history specimens or curiosities. Due in part to the development of mathematical and physical instruments, which became more widely available, scholars were confronted with the informative value of numbers. On the one hand, sequences of measurements appeared to be the key to the advancement of scientific knowledge, yet on the other hand the mathematical apparatus to deal with these data was still largely lacking. As a result of this the first meteorological networks organized in the eighteenth century all became bogged down in the large amount of information that was collected but could not be processed properly. This development is illustrated in a case study of an early Dutch meteorological society, the Natuur- en Geneeskundige Correspondentie Sociëteit (1779–1802). What were the factors that triggered this interest in the weather in the Netherlands? What were the goals and expectations of the contributors? What were their methodological strategies? Which instruments were used to measure which meteorological parameters? How was the stream of numbers generated by these measurements organized, collected and interpreted? An analysis of this process reveals that limits on the advancement of meteorology were not only imposed by instrumentation and organization. The financing, the scientific infrastructure of the old eighteenth-century Dutch Republic and the lack of a proper theoretical insight were also crucial factors that eventually frustrated the breakthrough of meteorology as an academic science in the Netherlands. This breakthrough was only achieved in the second half of the nineteenth century.

In 1873 the chair of geology at the University of Cambridge fell vacant following the death of Adam Sedgwick. Nine candidates stepped forward, hoping to fill the post. The correspondence generated in the ensuing battle illuminates two areas of particular interest. First, the strategies hidden behind bland lists of successive professors: candidates, peers and patrons manoeuvred to influence the outcome of the competition and competitors tried to reinforce their geological respectability by collecting testimonials from estimable geological acquaintances. Second, the Woodwardian competition inspired some outspoken opinions from British geologists about the relative worth of the candidates, which offer a fresh perspective on the process of professionalization in nineteenth-century science. The applicants came from various backgrounds, including gentlemanly amateurs, clerical geologists, Survey geologists and professors. Judging from the opinions of their peers, it seems that a non-professional or clerical status was rarely of primary concern in defining geological respectability at this time.
