Even so, Fox’s instruments remained central to Britain’s global networks of trade, commerce and data collection. Collaborating with Sabine, he co-ordinated a world-wide system for measuring several types of magnetic characteristics in a wide range of situations. This entailed years of thorough tests and modifications, paying close attention to every single aspect of an instrument’s construction and perform- ance. For example, a sensitive dipping needle developed to provide extremely accurate observations on land might be insufficiently robust for making reli- able measurements in the middle of an ocean; readings could also be affected by many other factors, such as temperature, so that experience was needed to detect and correct discrepancies. Over many years, Fox continually assessed and refined his compasses under different conditions, instigating an inten- sive programme to make sure that all the observers were thoroughly trained. Establishing centralised control over this global project involved standardising personnel as well as the equipment they were using. The detailed density of Gillin’s text testifies to his assiduous research skills in libraries and archives, but this lecturer in history possesses a more unusual expertise—he spent three months sailing TI - Towards Modern Nationhood: Wales and Slovenia in Comparison, c.1750–1918, by Robin Okey JO - The English Historical Review DO - 10.1093/ehr/ceae248 DA - 2024-11-19 UR - https://www.deepdyve.com/lp/oxford-university-press/towards-modern-nationhood-wales-and-slovenia-in-comparison-c-1750-1918-i8040sIg6Q SP - 1600 EP - 1602 VL - 139 IS - 601 DP - DeepDyve ER -
