Bibliotheca Walleriana 10856 (listing the first edition publ. in 1718 as Descriptions et usages de plusieurs nouveaux microscopes, tant simples que composez). The second enlarged edition of a scientific work concerning microscopy by the French naturalist Louis Joblot (1645-1723). "The publication of Descriptions established Joblot as the first French microscopist. The first part of the book described several microscopes and their construction and introduced some improvements, including the use of stops (diaphragms) in compound microscopes to correct for chromatic aberration. Joblot designed the first porte loupe, a simple preparation microscope in which the lens is supported by a string of 'Musschenbroek nuts,' forming a ball-and-socket jointed arm." (DSB VII, p.110).
