Researches on magnetism, electricity, heat, light, crystallization, and chemical attraction : in their relations to the vital force / By Karl, Baron von Reichenbach. Tr. and ed. at the express desire of the author, with a preface, notes, and appendix, by William Gregory. With three plates and twenty-three wood-cuts. Parts I and II, including the second edition of the first part, cor. and improved.
A mid-nineteenth-century English translation by William Gregory of Karl von Reichenbach's natural philosophy treatise on magnetism, electricity, heat, light and crystallization, published in London and Edinburgh in 1850. The pictures are line diagrams of compass-like star charts, with labelled radiating arrows naming colours at each direction, set against plain cream paper. A designer might take from them a clean radial layout for showing colour directions or a systematic, diagrammatic scheme for organising a set of hues around a central point.
