'This sparkling study of eighteenth-century science challenges modern assumptions that the microscope was usually regarded as little more than a scientific toy. By taking an entirely fresh approach, Marc J. Ratcliff shows that eighteenth-century microscopy in Europe is shockingly underestimated. Path-breaking work was indeed produced by scientific researchers. One innovative aspect is that he brings together many different individuals and different research traditions - for the first time, microscopy can be seen as an international enterprise, where correspondence, texts, illustrations, instruments, and specimens regularly crossed national boundaries and helped create a unique body of achievement. Another is to focus on the actual practices of microscopical investigation. Here Ratcliff evocatively describes the difficulties scholars encountered in representing the world of the invisible, and how they struggled to come to a consensus about visual and verbal conventions to indicate phenomena such as scale. Yet another is to critique the way we look back into the past with modern specializations in mind. These microscopical workers were as keen to philosophize about spontaneous generation and the origins of life as they were to investigate pond water or hunt for specks of living matter in detritus. Along the way, we come across a wonderful menagerie of animalcules, cochineal insects, polyps, and fungi. The world of the very small is revealed as problematic and utterly intriguing to the eighteenth-century people who attempted to describe it. Comprehensive, provocative, revisionist- this highly original book is sure to excite comment and command respect.'
